# What you need:

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

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

→ 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 advice:

01 -
  • The cool mint layer cuts through all that rich fudgy chocolate in the most perfect way
  • They look impressive but come together faster than you'd expect, especially if you start the night before
02 -
  • Let the brownies cool completely before adding the mint layer or the frosting will melt into a weird, speckled mess
  • Warm your knife under hot water and wipe it clean between cuts for the neatest squares that actually look like the photos
03 -
  • Chill the brownies briefly before spreading the mint layer and you'll get fewer brownie crumbs mixed into the green frosting
  • A little pinch of salt in the chocolate topping balances the sweetness and makes all the flavors sing together
