Irresistible Frosted Mint Brownies

What are your thoughts on special flavors of Oreos? Yay or Nay? I love trying them and there are some I love, hello lemon (and these Lemon Oreo Truffles!) and cookie butter Oreos. And some flavors that I never want to taste again, goodbye apple pie and birthday cake.

We’ve seen most of these flavors come and go, but mint Oreos must be a perennial favorite because you can always find them in the store.

I’m thankful for that because it turns out that I like mint Oreos even more than regular Oroes. Mint is kind of like a magic ingredient for the way it simply makes chocolate even better!

Mint Oreo Brownies

First things first, this recipe uses the entire package of mint Oreos. I recommend buying two packages, one package for the oreo lovers who won’t be able to stay out of them, and one to use to actually make the brownies.

The brownie base for this recipe is my simple cocoa brownie recipe. (I also use it in this recipe for mint brownies with chocolate ganache.)

Layer half the brownie batter in the pan and top with 24 mint Oreos. Spread the remaining batter over the Oreos, bake, and cool. While the brownies are cooling, whip up the mint buttercream frosting.

Spread the frosting on top, crush or roughly chop the remaining Oreos and sprinkle on top. Make a 30 second fudge drizzle in the microwave to add on top for a finishing touch. Cut, serve, and enjoy!

Total Time: 1 hr 40 mins
Cuisine: American
Servings: 24 brownies


For the Brownies

  • ½ cup butter
  • ½ cup oil
  • 2 cups granulated sugar
  • 4 eggs
  • 2 teaspoons vanilla
  • ¼ teaspoon mint extract
  • cup cocoa powder
  • 1 cup all purpose flour
  • ½ teaspoon salt
  • ½ teaspoon baking powder
  • 1 15.5 ounces package Mint Oreos

For the Mint Buttercream

  • ½ cup butter softened
  • 1 ¾ cups powdered sugar
  • 1-2 tablespoons heavy cream or milk
  • ¼ to ½ teaspoon mint extract
  • a few drops green food coloring

For the Fudge Drizzle

  • 3 tablespoons butter
  • 3 tablespoons cocoa powder
  • 1 tablespoon corn syrup or honey
  • 1/2 cup powder sugar
  • 1-2 tablespoons milk or heavy cream


Brownie Instructions

  • Preheat oven to 350°F. Grease and flour a 9 x 13 inch pan. Melt the butter in a large microwave safe bowl. Whisk in the oil, sugar, eggs, vanilla and mint extracts. Beat in the cocoa, flour, salt and baking powder.
  • Spread half the batter into the prepared pan, layer on 24 whole mint oreos and spread the second half of the batter on half. Bake for 25-30 minutes or until an inserted toothpick comes out with a few crumbs. Let cool completely.

Frosting Instructions

  • Beat the butter in a stand mixer for 1-2 minutes, beat in the powdered sugar. Add enough of the milk or cream to be a spreadable consistency and the mint extract to your tastes. Spread on top of cooled brownies.
  • Gently crush the remaining oreos in the package and sprinkle on top of the frosted brownies.

Fudge Drizzle Instructions

  • Melt the butter in a medium microwave safe bowl. Stir in the cocoa powder, corn syrup, powdered sugar, and enough milk or heavy cream to make a smooth consistency. Microwave up to 20 seconds, as needed, and stir.
  • Drizzle on top of cooled brownies. I put mine into a ziploc bag and cut the corner off for a more controlled drizzle. Let cool and cut into bars.
