Featured Ingredients

  • Cocoa powder: cocoa powder is what makes these super chocolatey.
  • Flour: all-purpose flour is a classic brownie ingredient. We don’t recommend swapping for anything else.
  • Butter: you’ll need unsalted butter for this recipe. We also tested it with coconut oil (see note in the recipe card).
  • Brown sugar: light brown sugar is the sweetener.
  • Peppermint extract: in addition to Thin Mint Cookies, we’re using a little peppermint extract to make these super minty!
  • Eggs: you need 2 large eggs for this.
  • Chocolate chips: chocolate chips help make these mint brownies extra fudgy.
  • Thin mint cookies: if you have real Thin Mint cookies, we suggest those, but you can also use any chocolate mint wafer cookie such as THESE.

Ingredients

  • 1/2 cup unsweetened cocoa powder
  • 1/2 all-purpose flour
  • ½ teaspoon salt
  • 1/2 cup unsalted butter melted (or 3/4 cup melted coconut oil)
  • 3/4 cup light brown sugar
  • ¾ teaspoon peppermint extract
  • 2 large eggs
  • 1 cup semi-sweet chocolate chips
  • 9 Thin Mint cookies or any mint chocolate wafer cookie (+ 2 more for an optional topping)
  • ¼ teaspoon flaked salt optional

Instructions 

  • Preheat the oven to 350º and spray an aluminum loaf pan with nonstick cooking spray.

  • In a medium sized bowl mix the cocoa powder, all-purpose flour, and salt together. Pour the dry ingredients through a sifter (or fine mesh strainer) to make sure there are no lumps in the dry ingredients. Set aside.

  • Next, add melted butter, brown sugar, and peppermint extract to a large bowl and mix together on medium/low with a hand held mixer or stand mixer (using an electric mixer is important).

  • In a separate small bowl, add the chocolate chips and melt them in the microwave on high for 15 second intervals, stirring and repeating until the chocolate chips are melted. Set aside.

  • Crack the eggs into the bowl with the butter and sugar mixture and mix on low with a mixer until the eggs are combined.

  • Add melted chocolate chips to the butter mixture and mix on low until all the ingredients are mixed together.

  • Slowly add the flour and cocoa powder to the bowl with the chocolate mixture and mix on low until combined.

  • Pour half of the brownie batter into the greased loaf pan. Then, place 9 thin mint cookies on top of the brownie batter.

  • Pour the remaining brownie batter over the thin mint cookies. Optionally sprinkle on 2 coarsely chopped Thin Mints on top.

  • Bake the brownies at 350ºF for 22-25*.

  • Remove from the oven and sprinkle with flaked sea salt. Let the brownies sit for 10-15 minutes before removing them from the pan.

Tips & Notes

  • Bake time varies based on the oven and remember that these are fudgy brownies, so you want them gooey in the middle! Be careful not to overbake.
  • We strongly recommend using an electric hand mixer to get out all of the lumps.
  • Make sure to use an aluminum loaf pan NOT a ceramic or glass loaf pan.
  • We used parchment paper in the pan and it was a game changer.
