The softest, most tender peanut butter cookies, sandwiched together with rich peanut butter frosting! These Peanut Butter Oatmeal Sandwich Cookies are a homemade version of the Girl Scout cookies called Do-si-dos.

I did it again you guys. I showed up to my son’s kindergarten pick up when I had arranged earlier in the week for a friend to pick him up that day. Why can’t I remember anything?? This has probably happened 4 or 5 times this year. At least this time I met my friend there, instead of what usually happens, which is that she picks up Truman on time and is already gone by the time I show up to get him a couple minutes late. Doh!
There is a torrential downpour going on right now. In California! In May! It’s so weird. Although I suppose I shouldn’t be surprised. Eleven years ago when Eric and I got married on May 24th, it rained on our outdoor wedding reception. I remember I kept repeating to myself, “April showers bring MAY FLOWERS, come on California!!”
We had to move the entire reception from my aunt’s beautiful backyard into the house, which we had most definitely not planned for. It was a bit of a disaster as far as parties go. My mom will still randomly mention mishaps that occurred that night that they didn’t tell me about to keep me from stressing out. Like the autographed baseballs that were on display in the house that some kid threw into the pool. Or the fact that the carpet in the house was such a wreck after 150 wet guests tramped over them that it had to be replaced.
I look back on it now and laugh. Guess what? Eric and I are still married! Receptions are just parties anyway, right? Our real wedding took place that morning in the temple. Despite all the mishaps, I still remember it as one of the most perfect days of my life. Being married is great you guys. Happy 11 years to us!
To celebrate, I made Eric some peanut butter sandwich cookies. What says I love you more than peanut butter? Basically nothing.
Peanut butter ftw!
These cookies are perfect because there’s peanut butter packed in the cookies AND the filling. I can’t be the only one who snacks on spoonfuls of peanut butter every now and then, right? It’s so delicious. My kids eat it every day on sandwiches, the only argument being about jelly and honey. The peanut butter is never questioned. I’ve included some recipes below using peanut butter that you won’t want to miss! You can also head here for even more peanut butter recipes.
How to make Peanut Butter Sandwich Cookies
These peanut butter sandwich cookies could not be easier! It’s a really simple dough.
I could probably eat this whole giant spoonful in one blissful afternoon.
But if you can resist, refrigerate the dough for a while, then scoop into balls using a cookie scoop, and bake for about 8-10 minutes. The resulting cookies are soft, tender, and the perfect level of puffy in the middle: enough to be thick and soft, but not so much that it’s annoying to bite into a sandwich when they’re doubled up.
Once the cookies have cooled, whip up a simple peanut butter frosting and spread it on the bottom of a cookie. Sandwich them together and voila! The best peanut butter sandwich cookies ever.
These cookies are copycats of the famous peanut butter sandwich Girl Scout cookies, have you ever had them? In some regions they’re called Do-si-dos. (I had no idea until recently that Girl Scout cookies have different names according to region. Crazy right?) They are so good, but not as good as these ones just out of the oven. I mean you just can’t beat that freshly baked flavor!

Peanut Butter Oatmeal Sandwich Cookies
For the cookies
- 1/2 cup butter, softened (1 stick)
- 1/2 cup butter-flavored shortening*
- 1 cup dark brown sugar, or light
- 3/4 cup granulated sugar
- 1 cup creamy peanut butter
- 2 large eggs
- 1 teaspoon vanilla
- 1 & 1/2 cups flour, spooned and leveled
- 2 teaspoons baking soda
- 1 teaspoon kosher salt
- 1 cup quick oats**
- 1/2 cup old fashioned oats**
For the frosting
- 4 tablespoons butter
- 1/2 cup creamy peanut butter
- 1 cup powdered sugar
- 2 tablespoons milk , OR cream plus more
- 1 teaspoon vanilla
- In a large bowl or stand mixer, beat 1/2 cup butter and 1/2 cup shortening for 2 minutes, scraping the sides and bottom.
- Add 1 cup brown sugar and 3/4 cup white sugar. Beat for 2 minutes, until light and fluffy, scraping the sides and bottom of the bowl.
- Add 1 cup peanut butter and beat until incorporated.
- Add 2 eggs and 1 teaspoon vanilla. Beat well, scraping sides and bottom.
- Add 1 and 1/2 cups flour but don't mix it in. Use a small spoon to stir 2 teaspoons baking soda and 1 teaspoon salt into the flour. Then beat the dry ingredients gently into the wet ingredients. Stop mixing when there are still flour streaks.
- Add 1 cup quick oats and 1/2 cup old fashioned oats. Stir until incorporated but do not over mix. Make sure you scrape the sides and bottom.
- Cover the bowl and chill the dough in the fridge for 1-3 hours (or overnight).
- When the dough is chilled, preheat the oven to 350 degrees F. Line 2 baking sheets with silicone baking mats or parchment paper.
- Use a 1 inch cookie scoop to measure out the dough.
- Bake the cookies at 350 for 8-10 minutes until the centers have just barely lost their shine. The edges should be firm. Do not over bake.
- Let cool on the sheet for 5 minutes before removing to a cooling rack. Let cool completely while you make the frosting.
- Make the frosting: In a large bowl or stand mixer, beat the butter until it is smooth and creamy. Add 1/2 cup peanut butter and combine.
- Add 1 cup powdered sugar and beat, scraping the sides.
- Add 2 tablespoons of milk or cream to start. Add 1 teaspoon vanilla.
- Add more milk or cream, a couple teaspoons at a time, until it has reached a good spreading consistency that you like.
- Spread about a tablespoon of frosting on the bottom of each cookie, then sandwich with another cookie. Devour! So good dipped in milk.
These cookies are pretty good! The purpose of chilling the dough is to keep the cookie from spreading too much. Needless to say my first tray was smaller than the rest but that doesn’t even matter. It’s a very rich cookie. My peanut butter loving bf loves them too!
I made these because my kids ate all the girlscout cookies, hubby was disappointed he didn’t get any.. found this recipe, made it. Its a forever keeper. Thank you Karen. Made some for a party, and they enjoyed them. Recipe was shared!
Absolutely amazing! I’ve been looking for the perfect peanut butter soft chewy cookie recipe for along time! I made these and hands down won the best peanut butter cookie award in my house..I will definitely be making them again!
Was wondering if natural peanut butter will work? All I have and want to make asap!!
Hi Lynda! I haven’t tried it with natural! You might need to up the sugar a bit. Let me know how it goes!
Hi! I can’t wait to make these for my birthday cookie bash! Can the dough be portioned and frozen for 48 hours before baking or do they need to be baked immediately?
Hey Bree! Birthday cooke bash!! That sounds awesome! I want to do that for my next birthday! How fun. And YES you can totally freeze this dough. I literally have some in my freezer right now. It will work great. You can bake from frozen, it just takes a couple more minutes. You can also make the frosting a day ahead. Enjoy!
I have a bunch of food allergies and fortunately peanuts aren’t one of them BUT I am allergic to wheat, dairy, and eggs. Do you know how they would turn out if I sub in oat flour, non dairy butter, and a chia or flax egg? I’m not much of a baker but these look sooo good!! I don’t want to miss out!!
Hi Annette! I’m so sorry, I don’t have much experience with alternative ingredients. Hopefully it works out for you!
What are the calories in these cookies.
Hi Tara! I don’t provide nutrition facts for my recipes, but you can easily plug the ingredients into a calculator online. Good luck!
Just made these and they are wonderful!
Will definitely try this recipe once I am back on my feet – had the tendon reattached to the ankle bone – and as my husband (of 42 years) is not too fond of peanut butter I will be able to eat them all!
I used to love nutter butters and homemade ritz crackers so this looks like such a great homemade version!!!
I need to make these cookies ASAP! I love oatmeal cookies but I don’t have a peanut butter one!
Wow. Those look mind blowingly good. That peanut butter frosting in the middle looks like it seals the deal perfectly! I can’t wait to try it. Pinning now to make soon.
I should not read your blog posts when I’m hungry. Right not I’m totally starving and looking at the peanut butter cookies is pretty much torture. I’m doing intermittent fasting and I don’t get to eat for a couple more hours so thinking about these cookies is making me crazy.
How is a person supposed to lose, or even maintain their weight in the face of such temptation you present before us, Karen?????
Made a double batch just waiting for it to chill. Just realized your Chewy Peanut butter oatmeal cookies (that I discovered from Pinterest) is the same batter you have going on here. I loved those cookies! Thanks for delicious oatmeal peanut butter cookies!
Yes, same base dough! I tried a couple versions but kept coming back to this one. So chewy! So soft! Thanks so much for commenting Alyona!! <3
