03 - 1 cup light brown sugar, packed
04 - 4 large eggs, room temperature
05 - 2 tsp vanilla extract

# How-to Steps:

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 Pointers:

01 -
  • The combination of fudgy chocolate brownie and creamy mint frosting is surprisingly elegant, like something from a bakery but actually achievable at home
  • These keep beautifully in the freezer, meaning you can pull out a single square whenever that chocolate mint craving strikes at midnight
02 -
  • The brownies MUST be completely cool before you add the mint layer or the butter will melt and your beautiful green frosting will slide right off
  • A hot knife dipped in water between cuts will give you those perfect clean squares instead of jagged messy edges
03 -
  • The green food coloring is completely optional but makes the mint layer instantly recognizable and surprisingly appealing
  • Room temperature ingredients are your best friend for both the brownie batter and the frosting so plan ahead
