# Ingredient List:

→ Brownie Base

01 - 1/2 cup unsalted butter
02 - 4 oz semi-sweet chocolate, chopped
03 - 1 cup granulated sugar
04 - 2 large eggs
05 - 1 tsp vanilla extract
06 - 1/2 cup all-purpose flour
07 - 1/4 cup unsweetened cocoa powder
08 - 1/4 tsp salt

→ Mint Cream Layer

09 - 1/4 cup unsalted butter, softened
10 - 1 1/2 cups powdered sugar, sifted
11 - 2 tbsp whole milk
12 - 1/2 tsp peppermint extract
13 - Green food coloring, as needed

→ Chocolate Ganache

14 - 4 oz semi-sweet chocolate, chopped
15 - 1/4 cup heavy cream
16 - 1 tbsp unsalted butter

# How to Prepare:

01 - Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a saucepan over low heat, melt butter and chocolate for the brownie base, stirring until smooth. Remove from heat.
03 - Whisk in sugar until combined. Add eggs, one at a time, whisking well after each addition. Stir in vanilla.
04 - Sift in flour, cocoa powder, and salt. Fold gently until just combined—do not overmix.
05 - Spread batter evenly in prepared pan. Bake for 25–30 minutes, or until a toothpick comes out with a few moist crumbs. Cool completely in the pan.
06 - Beat butter until creamy. Gradually add powdered sugar, milk, peppermint extract, and a few drops of green food coloring until a smooth, spreadable frosting forms.
07 - Spread mint cream evenly over the cooled brownie base. Chill in the refrigerator for at least 30 minutes.
08 - Place chocolate and butter in a heatproof bowl. Heat cream until just simmering, then pour over chocolate. Let stand 2 minutes, then stir until smooth.
09 - Pour ganache over mint layer, spreading evenly. Chill brownies for at least 1 hour, or until set.
10 - Lift brownies out of the pan using the parchment overhang. Cut into 16 squares with a sharp knife, wiping the blade between cuts for clean edges.

# Expert Suggestions:

01 -
  • The texture alone will convert anyone who claims they hate mint chocolate things—fudgy brownie, creamy mint frosting, and silky ganache create this incredible three layer experience
  • Theyre actually make ahead friendly since they need chilling time, meaning you can prep them a day before a party and not stress about last minute dessert disasters
  • That green layer is your chance to go subtle and sophisticated or full on festive St Patricks Day bold depending on your food coloring courage
02 -
  • The chilling time between layers is non negotiable—warm brownies under mint cream means the frosting slides right off, and soft mint layer under ganache gives you a swirled muddy mess instead of clean distinct layers
  • Use a sharp knife heated under hot water and wiped dry between cuts for those picture perfect clean edges
03 -
  • Add a pinch of salt to the ganache—just a tiny pinch makes the chocolate flavor pop and balances the sweet mint layer
  • If your mint layer feels too thick to spread easily, microwave it for 5 seconds and stir—it'll loosen right up without compromising texture
