05 - Bake for 25-30 minutes until a toothpick inserted in the center emerges with a few moist crumbs. Cool completely in the pan before proceeding.
06 - Beat softened butter until creamy. Gradually incorporate powdered sugar, milk, peppermint extract, and food coloring if using. Mix until smooth and spreadable.
07 - Spread mint filling evenly over the cooled brownie base. Refrigerate for 20 minutes until firm.
08 - Melt chocolate chips and butter together using microwave or double boiler, stirring constantly until smooth and glossy.
09 - Pour chocolate topping over mint layer, spreading evenly. Refrigerate for 30 minutes until completely set.
10 - Lift brownies from pan using parchment paper overhang. Cut into 12 squares and serve chilled or at room temperature.

# Expert Advice:

01 -
  • The cool mint cuts through the rich fudgy brownie creating that perfect thin mint cookie experience everyone secretly craves
  • These look impressive but come together with simple pantry staples you probably already have
02 -
  • Let the brownies cool completely before adding the mint layer or the butter will melt and slide right off creating a minty mess instead of a smooth layer
  • Chill the mint layer for at least 20 minutes before pouring the warm chocolate topping otherwise they will swirl together and you will lose those distinct layers
03 -
  • Add a pinch of espresso powder to the brownie batter to intensify the chocolate flavor without making them taste like coffee
  • If your mint layer feels too stiff to spread pop it in the microwave for 10 seconds it will soften right up
