Ingredients

Mint Cookie Brownies

  • 1 cup (2 sticks) salted butter melted
  • 2 cups granulated sugar
  • 4 large eggs
  • 6 tablespoons unsweetened cocoa powder
  • 2 teaspoons vanilla extract
  • 2 cups all-purpose flour
  • 1 cup crushed Keebler Grasshopper Cookies (or Thin Mints)

Andes Mint Frosting

  • 2 packages (4.67 oz each) Andes Mint Chocolates

Instructions

  • Heat oven to 350℉. Prepare a 9x13 baking dish by spraying with cooking spray or lining with parchment paper for easy removal.
  • In a large mixing bowl, whisk together the melted butter and sugar until combined.
    1 cup (2 sticks) salted butter, 2 cups granulated sugar
  • Add eggs, one at a time, mixing the egg into the batter with the whisk before adding the next egg.
    4 large eggs
  • Add cocoa powder and vanilla extract. Stir to combine.
    6 tablespoons unsweetened cocoa powder, 2 teaspoons vanilla extract
  • Add the flour and stir together until no flour streaks remain in the batter.
    2 cups all-purpose flour
  • Add the chopped cookies into the brownie batter and stir to combine.
    1 cup crushed Keebler Grasshopper Cookies
  • Evenly spread out the brownie batter into the pan. The batter is thick so it will take a few minutes to spread out. It helps if you dollop spoonfuls of it all over the pan and then spread it out. If you spray the back of a spoon with cooking spray you can use that to help spread it out too.
  • Bake for 25-32 minutes. The brownies will look slightly puffy and pulled away from the edges of the pan. A toothpick inserted in the middle should come out clean with no wet batter.
  • While the brownies are baking unwrap all the Andes Mints.
    2 packages (4.67 oz each) Andes Mint Chocolates
  • Right when the brownies come out of the oven, put the unwrapped Andes Mints in rows on top of the hot brownies. Let it sit for about 10 minutes and then take a spoon and spread out the melted mint chocolate over top the brownies.
    *OPTIONAL STEP : After you have spread the frosting out, you can chop up some additional Andes mints and sprinkle them over top the frosting. This just gives the brownies an extra special look with the chopped pieces on top (similar to what is pictured in the photos).
  • Let the brownies cool completely, inside the pan, at room temperature. As the brownies cool, the mint frosting will firm up and harden; it takes about 2 hours.
  • Cut into squares and serve at room temperature. Enjoy!

Notes

I always line my baking pans with parchment paper. A tip to get the paper to stay inside the pan is to first spray the pan with cooking spray, and then line with the parchment paper and press it in. The cooking spray helps the parchment paper stay in the pan. 
 
The size of Andes Mint Chocolates that you want are the ones that come in a small box and they are individually wrapped. You will find them in the candy aisle of the grocery store. 
 
If you want to make this easier feel free to use a box of your favorite store-bought brownies instead of the homemade brownies. These brownies are so much better with the homemade recipe, but can be made with a boxed brownie mix.Just make sure it's the 'family size' of brownie mix that bakes in a 9x13 baking dish.
