Mom’s Marshmallow Cream Fudge

For some families, Christmas goodies means cinnamon rolls. For some it’s toffee and candy. Eric’s family does cookies. My family growing up did this:

Marshmallow Fluff Fudge

Boom. Straight up, no messing around chocolate fudge. (This was one of the first recipes I posted on the blog back in 2012. Check out this picture from yesteryear, yikes!)


And by “no messing around” I mean no nuts, no peanut butter, no peppermint, no swirls, no fuss. Just pure semi-sweet, melt in your mouth goodness. (I have nothing against fudge-embellishments by the way. But sometimes you just can’t beat the classic.)

We made it every year in December. We would all hover over the stirrer (usually my mom) making sure they didn’t mess anything up. (Our faith is inspiring.) Then as she poured the completed fudge into the pan we would all make non-subtle comments about making sure not to do a too-good job scraping (so that we could attack the pan with our fingers of course).

She always poured a little bit into a small bowl, presumably so that it would set up faster for us. We never waited though. (I mean, have you eaten warm fudge?) My sister Nikki has been known to consume an entire batch of this fudge in a 12 hour period.

Most of the time we would give it away to friends and neighbors, which is of course a very effective way to spread Christmas cheer. One time it backfired on us though. We brought a plate of fudge for some friends and left it on the doorstep, figuring they would be home in a few hours. They came back from vacation a week later with an entire colony of ants on their porch. Nothing says Merry Christmas quite like a pest infestation.

But don’t think about that. Just think about dreamy, creamy, not-too-soft yet not-too-dry, non-crunchy, beautiful fudge. And go make this right now because it seriously takes like 15 minutes.

I’m about to give you ONE THOUSAND details for this recipe. Fudge is simple, but it is still candy, and it’s easy to screw up if you are not particular about the small stuff. You might think I’m being nit-picky, but I’m just trying to be thorough. Check the 300 comments that have been given over the past 10 years: mixed with the hundreds of glowing reviews, there are also a lot of commenters with sad, dry, crumbly fudge. I’m here to make sure this doesn’t happen to you!

Look at this abomination. It still tastes good, but the texture is alllll wrong. Chalky, dry, sad garbage fudge.

This crumbly mess is what happens to fudge when you don’t follow your own nit-picky fudge instructions because you were trying to take a hundred process shots for how to make this fudge. Don’t be like me!

Marshmallow Cream Fudge Ingredients

Let’s dig in to the details, folks. First and foremost: The best fudge starts with high quality ingredients! I cannot stress this enough!! Recipes always say this, right, and you always ignore it? But it actually matters for fudge. Candy making is no joke, and if you start with crappy ingredients, your fudge might not even turn out. Here’s an overview, quantities are listed in the recipe card below.

  • Butter. Salted butter is what I always use, but unsalted works fine too.
  • Granulated sugar
  • Evaporated milk. Get the full fat kind. This ain’t no diet fudge. Found in a can on the baking aisle.
  • Semi-sweet chocolate chips. Buy the best brand you can afford. I always use Ghirardelli or Guittard. Nestle works okay. Great Value from Wal Mart is a definite NO (avoid basically any generic brand.)
  • Marshmallow creme, also called marshmallow fluff. Found in a tub on the baking aisle.
  • Vanilla extract

Tips for making fudge right every time

These are the basics of what you need to know to make awesome fudge. Tons more details below:

  • Have all your ingredients measured out before you start making the fudge
  • Use high quality chocolate
  • Use marshmallow creme, not mini marshmallows
  • Use a heavy-bottom pot
  • Line your pan with parchment paper
  • Don’t get any sugar crystals on the side of the pan or on the spoon
  • Stir the whole time, 5 minutes, or until a thermometer reaches 234-236 degrees F
  • Pour the fudge into the pan but don’t scrape the edges of the pot well. I will explain everything below!!

How to Make a Fudge Recipe with Marshmallow Fluff

First, have EVERYTHING completely measured out and ready to go before you even turn your burner on. Fudge moves fast, so we need to be totally prepared! You might think that the top photo is what “everything ready to go” looks like. It’s not!

ingredients for fudge on a white counter, all ingredients prepared for fudge (lids off and measured)

One of these things is not like the other…In the second photo, I’ve peeled off the top of the marshmallow creme. I’ve measured out 2/3 cup evaporated milk. I’ve lined my pan with parchment paper. I’ve even torn open my bag of chocolate chips and spilled them artfully over the counter. (okay fine, you can skip that step.) I know you feel like I’m being bossy, but I promise, you do not have time to do this stuff later!

two brands of chocolate chips (generic, with an X to show not to use)) and ghirardelli

Now, about that chocolate. Here is an example of what NOT to buy. Do you see how the red package calls these “baking chips”? Guys, don’t do it. If you buy low quality chocolate, the chips will not melt all the way, and you will end up with chocolate chunks in what is supposed to be smooth, dreamy creamy fudge. My sister used crappy chocolate one time, and someone asked her if it was “chocolate chip fudge.” She just said yes, haha. But don’t be like that! Aspire higher! Use the best quality chocolate you can find. Ghirardelli, Guittard, and Lindt are all great brands.

a heavy bottom pot with a thumb showing how thick the bottom is

Next we’re going to talk about your pot. Yes, this really does matter! You need a heavy 3-quart pot. That means when you pick it up, it should feel HEAVY. Give it a swing! Sometimes people call these “heavy bottomed pans.” Can you see how thick the bottom of this pan is compared to the thickness of the edges?

A cheap thin pan will heat your fudge unevenly, creating “hot spots” and causing it to scald. This leads to dry, crumbly fudge. The pan quality REALLY CAN BE the difference between perfect fudge and failure fudge. Trust me!

Jet puffed brand of marshmallow creme with lid and foil peeled off

Next step on prepping: take the time to remove the foil seal from the top of your marshmallow jar before you get cooking. Sometimes they can be stubborn and you need two hands (you won’t have two hands later). I prefer Kraft jet-puffed, but that’s more for ease of opening than how it affects the fudge, I’ve used generic with good results. Later we will be warming this in the microwave so make sure ALL the foil comes off! Go ahead and stick the tub in the microwave now to hang out until you need it.

Open your can of full-fat evaporated milk and measure out 2/3 cup into a liquid measuring cup, and have your vanilla nearby with the teaspoon ready to go. All your ingredients should be really close to the stove, within arms reach. Once the fudge making starts you can’t leave. Get ready to holler at anyone in the house in case the doorbell rings or something. Trust me, I’ve done my fair share of fudge-hollerin.

One last thing: line your 8×8 or 9×9 inch pan with parchment paper before you get started. Fold the corners and tuck them in nicely. You can pour it straight into the pan if you want, but it’s so much easier to cut the fudge into clean slices if you can lift it out of the pan with paper. Now, if you plan to eat the whole thing by yourself, row by row, slicing little pieces for yourself every time you pass through the kitchen, then I have no judgment to pass on you, and you also can totally skip the parchment. No need to spray the pan.

Okay you can finally start cooking now

Whew! Now that we’ve gotten through all our prep, we can actually get to fudge making.

greasing the edge of a pot with melting butter using a knife
  1. Start by adding the butter and melting it over medium heat. As it melts, coat the edges of the pan clear to the top with the butter. This will help prevent sugar crystals from forming on the edges of the pan.
granulated sugar added to the center of a pot of melted butter

2. Once the butter is mostly melted, slowly pour the sugar into the center of the pan as carefully as you can, making sure to not get any sugar on the side of the pan. With a long wooden spoon, draw the butter in from the edges toward the center, going slowly all the way around the pan until the edges are moistened.

3. Add the evaporated milk and turn the heat up to medium high. Stir to mix evenly, but avoid touching the sides of the pan with your spoon. And let’s get this out of the way:

Can I use sweetened condensed milk instead of evaporated milk?

No! They are not the same. Like, at all. Don’t ever exchange them in any recipe. Good grief.

4. Bring your butter-sugar-evap-milk mixture to a boil, STIRRING GENTLY AND CONSTANTLY. Bubbles showing on the edges of the pan is not enough. Light bubbles must be coming up from the center of the pan, even when you swipe your spoon across the pan.

5. Immediately set a timer for 5 minutes, and turn the heat down to medium so that you don’t burn your fingers off. It should be boiling the full 5 minutes. STIR GENTLY AND CONSTANTLY. If the boil isn’t constant or starts to die a bit, the heat is too low and you need to turn it up a smidge. Keep stirring. Your hand may feel like it’s on fire at times. In fact, your arm might fall off from stirring this much, but you’ll be glad you burned some calories when you realize how much of this fudge you’ll be eating.

a rolling boil in a pot: sugar, butter, evaporated milk

Here is what the boiled mixture looks like after 5 minutes. It is lighter and foamier.

Another way to check for doneness is to use a candy thermometer, removing from the heat once the temperature reaches 234-236º F. My mom never did this, and I don’t either usually. But if you are nervous, 234-236 is the temperature you are shooting for. If you cook it to a higher temperature, your fudge will turn out dry and crumbly.

It’s go time, look alive people

Be ready the last few seconds before the timer goes off, all the next steps happen very quickly!

adding chocolate chips to boiled fudge mixture

6. As soon as the timer rings, turn off the burner and move the fudge pot off the heat. Immediately add all the chocolate chips at once. Stir with your wooden spoon until all the chocolate chips are melted and mixture is smooth. If you have chunks in this mixture, you will have chunks in your fudge, so be sure to stir until they melt completely.

7. Put your marshmallow creme in the microwave for about 10-15 seconds (no lid! no bits of foil! Ignore the “do not microwave this container” warning!) Watch it and take it out when the mallow rises about a bit over the lip of the container.

This step makes scooping the mallow creme out of the container like 10x faster, but you can skip it if you just love struggling with a spatula and getting marshmallow up to your elbows.

8. Add the marshmallow creme to the chocolate mixture and beat with a wooden spoon until mostly incorporated, then add the vanilla and stir until everything is even in color and well-blended.

Once you don’t see any more marshmallow swirls, STOP STIRRING. The fudge will start to set as soon as it starts cooling, even right there in the pot, so get a move on.

9. Pour the fudge into the prepared pan and gently shake it to help the fudge settle in. Do no touch the top of the fudge or spread it with a spatula. It should be gorgeously ridged on top, like this:

DO NOT scrape out the pot well! You will just be covering the top of your beautifully rippled fudge with already-crumbly-dried-out-edge-of-the-pan-bits. Don’t ruin the top of your fudge. I don’t even use a spatula, just the same wooden spoon I used to stir.

scraping the last bits of fudge from a pot, adding to a white bowl with a spatula

Once all the smooth liquid fudge is in the pan, get a spatula and carefully scrape all the remaining fudge into a small bowl. Then by golly, have at it with a spoon. Treat yoself. Everyone else has to wait hours to try this fudge, but not you, oh no. This bowl is a special treasure that no one else even has to know about.

10. Let your pan of fudge cool to room temperature before cutting into it. The fudge needs to set for several hours before it is ready to be lifted out and sliced, otherwise it will crack when you move it. If you’re leaving it in the pan you can cut into it while it’s warm, it’ll just be soft-set instead of firm.

11. Once it is totally cool, slice and serve! Store on the counter covered with plastic wrap. Do NOT store fudge in the refrigerator. It dries out super fast. I only cut pieces from the block of fudge as they are needed. The longer already-cut pieces sit out, the more dry they become. If you are only using part of the fudge, only cut what you need. If you are cutting the entire block for a party or to distribute on Christmas plates, wait until right beforehand to cut the pieces.

The easiest way is to grab the edges of the parchment paper and pull the entire block out of the pan. Use a long, sharp knife and cut several rows in one direction (wiping the knife between slices), then turn the block 90 degrees and cut more rows in that direction to make small pieces. The size of the pieces can be adjusted to however big or small you like. Remember that this fudge is rich and a little goes a long way! I usually cut fudge into rows of 7×7 to give me about 49 pieces of two-bite fudge.

Extra tips and FAQ for homemade fudge:

How many mini marshmallows equal a jar of marshmallow creme?

4 cups of mini marshmallows (or 40 large marshmallows) equals about one 7-ounce tub of marshmallow creme. But wait, why are you asking this?? There are no marshmallows in this recipe!

Can you use marshmallows instead of marshmallow fluff for this simple fudge recipe?

Ah, I see. YOU ARE TRYING TO CHEAT. You want to use regular marshmallows instead of marshmallow creme.

I get it, I get it. Maybe marshmallow creme is tough to find where you live. Maybe you just had a baby and can’t leave the house, but you NEED some fudge and all you have are minis. Or maybe you’re just being SUPER lazy and have no excuse.

Here’s the thing. While fudge made with regular marshmallows CAN turn out okay, I don’t recommend using them unless you’re desperate. Marshmallows are coated in cornstarch to keep them from sticking to each other in the bag. In fudge, the cornstarch dries out the fudge and makes for a not-quite-as-smooth texture. The older the marshmallows, the drier and tougher your fudge will get. Regular marshmallows should be a last ditch effort for fudge. So get your booty down to the store and buy the real stuff, if you can get your hands on it!

If you do plan to use marshmallows, it’s best to use a kitchen scale to weigh out 7 ounces of marshmallows (the amount in a tub of marshmallow creme) rather than relying on cup measurements.

Why is my marshmallow fluff fudge grainy?

You’ve heard one bad apple ruins the bunch, but in this case, it’s one rogue grain of crystalized sugar.

Fudge is super-saturated with sugar. Fudge has more sugar molecules inside its buttery-goodness than technically “fit” inside. You crammed all those sugar molecules inside by getting the mixture hot over a stove, so the fats could absorb more and more of the sugar. The fat should keeps absorbing until every speck of sugar is dissolved, if you do it correctly.

overhead picture of fluff fudge with a bite taken out of one

If your fudge is grainy, it means some sugar crystals remained in your mixture even after heating. These handful of crystals act like a ladder, allowing other dissolved sugar molecules to climb out of the liquid and adhere to the crystalline structure, similar to the way rock candy grows into crystals when water evaporates. Crystals = grainy.

Here’s how to avoid grainy fudge:

  • Coat your whole pot with melted butter before adding the sugar. This makes it tougher for sugar to stick to the edge of the pot.
  • Melt the butter slowly and add the sugar very carefully to the center of the pot, without getting ANY on the sides. If you accidentally get some on the side, carefully douse it with the butter and evaporated milk mixture to make sure it doesn’t crystalize (which would then form those “ladders” of sugar crystals, making grainy fudge)
  • Avoid getting sugar crystals on the upper edge of your wooden spoon. If you see dry sugar on your spoon, make sure to douse it with the liquid in the pan before you’ve reached a boil.
  • Make sure you pour the hot mixture into a prepared pan that is completely dry and clean (and preferably lined with parchment). Water introduced at this point will ruin your whole batch of fudge.

How do I fix fudge with marshmallow fluff that didn’t set?

Okay, here’s the hard truth. Fudge can be sensitive. Think of it like your favorite, but occasionally-weepy, holiday relative. Every season it’s something new: the humidity, the altitude, the barometric pressure (for reals).

This recipe is very forgiving, as far as fudge recipes go. But it’s still fudge. The butter mixture you stirred for so long needs to reach 234-236º F to set properly. (This takes about 5 minutes! I NEVER use a candy thermometer for fudge and neither does my mom).

simple fudge recipe with squares on parchment paper, chocolate chips and red string

If your fudge doesn’t set (become hard), it likely didn’t reach 234-236º F. Although I’ve personally never had fudge that didn’t set, I’ve read that you can put all the fudge right back in the pan with a tablespoon or two of evaporated milk and reheat it all back up, using a thermometer to make sure it hits 234-236º.

If your fudge just won’t set, don’t throw it away! You have a few options.

  • If it’s really thin, use it as a fudge sauce over ice cream. Or spread it on top of Nana’s Fudge Brownies! Or honestly, just forget serving it to guests and go at it with a spoon.
  • If it’s thicker but still not set, try adding some powdered sugar, roll into balls, and dip in chocolate for fudgy truffles.
  • You can also just let it sit overnight, uncovered and unrefrigerated. The “gooey mess” will harden over time, becoming more brittle than is ideal, but still delicious, and less messy than unset fudge.
  • You can also try putting the fudge in the fridge and see if chilling will help it set.

If your fudge is always runny and you live in a high altitude, consider stirring the fudge mixture on the stove for 5 minutes and 30 seconds to give the mixture time to heat all the way. Or you can use a candy thermometer as you boil the fudge mixture, removing it from heat once it reaches 234-236º F.

Can you freeze fudge?

Yes you can! I do this every year at Christmas time. Seal the whole block (not cut pieces, if possible) in a ziplock. Take it out when you need it and let come to room temperature on the counter in the same bag. Do not try to slice until it’s completely room temperature. It will keep in the freezer for about 2 months if well sealed!

Oh, fudge.

Well, that’s all folks. The capstone course on fudge-making. You deserve a diploma. Thanks, Mom, for teaching us your fudge making ways. I hope this simple fudge recipe brings you as much happiness as it has brought my family over the years! Merry Christmas to all!

Mom’s Marshmallow Fudge

This no-fuss marshmallow fluff fudge recipe is for chocolate purists! It is smooth, creamy, and decadent, and you can't have just one piece!

Ingredients

  • 3/4 cup butter, this is 1 and 1/2 sticks; do not use margarine
  • 2 & 1/2 cups white granulated sugar
  • 2/3 cup full-fat evaporated milk, do not use sweetened condensed milk
  • 12 ounce package (high quality) semi-sweet chocolate chips, 2 cups
  • 7 ounce jar marshmallow cream, also called marshmallow fluff
  • 1 teaspoon vanilla extract

Instructions

  • Prepare your ingredients: For fudge-making, it's important to have everything completely measured out and ready to go before you turn your burner on. Fudge moves fast, so you need to be totally prepared!
  • Line an 8×8 or 9×9 inch square pan with parchment paper. Set aside.
  • Open your 12-ounce bag of HIGH QUALITY semi sweet chocolate chips. Remove the lid and all traces of the foil seal from the tub of marshmallow creme (we are microwaving it later).
  • Make the fudge: In a 3-quart HEAVY saucepan over medium heat, add 3/4 cup butter. (This is 1 and 1/2 sticks). Use a spoon to drag the melting butter up the sides of the pot, clear to the top, greasing the edges of the pan.
  • Once the butter is mostly melted, slowly pour 2 and 1/2 cups sugar into the center of the pan as carefully as you can, making sure to not get any sugar crystals on the side of the pan. With your wooden spoon, draw the butter in from the edges toward the center, going slowly all the way around the pan until it’s mostly moistened. Do not leave any sugar crystals on the side of the pan or on the edge of your spoon; it will make your fudge grainy. The goal is to dissolve all of the sugar.
  • Pour in 2/3 cup evaporated milk. Stir this mixture together thoroughly, making sure to douse any rogue bits of dry sugar with the liquid in the pan. All the dry sugar crystals need to be dissolved before the mixture reaches a boil.
  • Settle in for the boil: Bring the mixture to a full rolling boil over medium high heat. (Rolling boil means bubbles are coming up from the center of the pot.) Stir constantly with a long wooden spoon.
    Once it starts boiling, set a timer for 5 minutes and turn the heat down to medium so that you don't burn your fingers off. It should be boiling the full 5 minutes. Stir constantly. A candy thermometer should read about 234-236 degrees F at the end. Take it off heat early if it reaches 234-236 before 5 minutes. Overcooking at this stage makes for dry, crumbly fudge.
  • Add the chocolate chips. When the timer goes off, remove from heat and add 12 ounces chocolate chips all at once. Stir vigorously until all the chocolate chips are melted and mixture is completely smooth. (if there are lumps in this mixture, there will be lumps in your fudge. Get them all out).
  • Marshmallow creme. Heat your 7-oz tub of marshmallow creme in the microwave for about 10-15 seconds (to make it fast and easy to scoop out of the jar.)
    Move quickly. Add all the marshmallow creme to the chocolate mixture and beat with a wooden spoon until nearly blended.
  • Vanilla. Add 1 teaspoon vanilla and continue stirring until there are no more marshmallow streaks and the mixture looks even and smooth. Stop stirring as soon as it's combined.
  • Pour into final pan. Immediately pour into the prepared pan. Don't scrape the edges of the pot too well. Only pour fudge into the pan that is completely liquid and smooth. If the fudge-bits on the edges of the pot look dried out at all, leave them behind.
    Shake the prepared pan to help the fudge settle. Do not touch the top of the fudge or try to smooth it with a spatula. It should have a rippled appearance.
  • Let cool to room temperature. (Good luck with that.)
  • Slice and serve! I like to slice a square pan of fudge into 7×7 rows, making about 49 small pieces. Fudge is so rich!
  • Store on the counter covered with plastic wrap. Do not refrigerate. Unfortunately this means you will probably eat "just a sliver" of fudge every time you pass through your kitchen. Oh darn! This is one of the greatest joys of the season if you ask me!
