# What You Need:

→ For the Brownies

01 - 1 cup unsalted butter, melted
02 - 1 1/2 cups granulated sugar
03 - 1 cup light brown sugar, packed
04 - 4 large eggs, room temperature
05 - 2 tsp vanilla extract
06 - 1 cup all-purpose flour
07 - 1 cup unsweetened cocoa powder
08 - 1/2 tsp salt
09 - 1 cup semisweet chocolate chips

→ For the Mint Layer

10 - 3/4 cup unsalted butter, softened
11 - 2 cups powdered sugar, sifted
12 - 2 tbsp whole milk
13 - 1 1/2 tsp peppermint extract
14 - Green food coloring (optional)

→ For Topping

15 - 1/2 cup semisweet chocolate chips, melted
16 - 2 tbsp unsalted butter

# Directions:

01 - Preheat the oven to 350°F. Line a 9x13-inch baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a large bowl, whisk melted butter, granulated sugar, and brown sugar until combined. Beat in eggs one at a time, then add vanilla.
03 - Sift in flour, cocoa powder, and salt. Stir until just combined. Fold in chocolate chips.
04 - Spread the brownie batter evenly into the prepared pan. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Cool completely in the pan.
05 - Beat softened butter until creamy. Gradually add powdered sugar, milk, peppermint extract, and a few drops of green food coloring (if using). Beat until smooth and spreadable.
06 - Spread the mint layer evenly over the cooled brownies. Refrigerate for 20 minutes.
07 - Melt chocolate chips and butter together in a microwave or double boiler until smooth. Cool slightly, then pour over the mint layer. Tilt the pan to cover evenly.
08 - Refrigerate for 30 minutes or until set. Lift brownies out using the parchment overhang and cut into squares.

# Expert Suggestions:

01 -
  • The contrast between cool mint and rich fudgy brownie is absolutely worth the extra steps
  • These look impressive but actually come together with straightforward techniques you already know
  • They freeze beautifully, making them perfect for unexpected guests or midnight cravings
02 -
  • The brownies must be completely cool before adding the mint layer—warm brownies will make the butter separate and look curdled
  • Letting each layer set properly in the fridge is what creates those clean, professional-looking slices
  • Use a sharp knife and wipe it clean between cuts for the prettiest squares
03 -
  • Run your knife under hot water between cuts for perfectly clean slices
  • If your mint layer is too stiff, add another teaspoon of milk; too thin, add more powdered sugar
  • The chocolate topping sets faster at room temperature than in the fridge, giving you a smoother finish
