Thin Mint Mint Cookies

It's like cookie inception: a cookie...in a cookie! Two cookies in one has never been a bad idea, but this one is particularly fabulous because there are THIN MINTS involved. Come on, I know you're obsessed. They are perfectly green for St. Patrick's Day!

  • 1 cup butter softened (2 sticks)
  • 1 & 1/2 cups sugar
  • 2 large eggs plus 1 egg yolk
  • 1/2 teaspoon peppermint extract or more to taste
  • 10-15 drops green food coloring
  • 3 & 1/4 cups all-purpose flour spooned and leveled
  • 2 teaspoons baking powder
  • 1 teaspoon baking soda
  • 1 teaspoon cream of tartar
  • 1/2 teaspoon kosher salt
  • 1 box Thin Mints or grasshopper cookies
  • chocolate chips to top with (optional)


  • Preheat the oven to 350 degrees F. Line one or more baking sheets with parchment paper or a silpat.
  • In a large bowl or stand mixer, beat the butter and sugar together. Scrape the sides and bottom of the bowl, then beat on medium for about 2 minutes, or until light and fluffy.
  • Add the eggs + yolk, peppermint extract, and food coloring.
  • In a separate bowl, combine flour, baking powder, baking soda, cream of tartar, and salt. Add to the wet ingredients and combine until the flour is not quite incorporated.
  • Use a sharp knife to chop about 30 Thin Mints into quarters. Chop a few extra and set aside.
  • Gently stir the cookies into the dough. Don't go crazy, you want the cookie chunks to stay big. 
  • Cover the dough and refrigerate for about an hour.
  • Use a 1/4 cup measuring cup to form balls of dough and shape them into a long oval shape (not a ball shape, think more egg shape). Press a couple more cookie chunks into each cookie if they are looking sparse.
  • Place them on the cookie sheet (the tall way) lined with parchment paper or a silicone mat. These are very large cookies, I only did 8 cookies per pan.
  • Bake at 350 for about 8-10 minutes, or until BARELY starting to brown on the edges. The centers should mostly be not-shiny when you take them out, but a little shine is okay.
  • Immediately press several chocolate chips into the top of each cookie. (You can skip this step if you want, but who says no to more chocolate?)
  • Let cool 5 minutes on the pan, then remove to a cooling rack.
