Ingredients
Brownies
- 1 cup (16 Tbsp; 226g) unsalted butter
- 8 ounces semi-sweet chocolate, coarsely chopped
- 1 and 1/2 cups (300g) granulated sugar
- 1/2 cup (100g) packed light brown sugar
- 4 large eggs, at room temperature
- 2 teaspoons pure vanilla extract
- 1/2 teaspoon salt
- 1/2 cup + 3 Tablespoons (86g) all-purpose flour (spooned & leveled)
- 1/4 cup (21g) natural unsweetened cocoa powder
Mint Frosting Layer
- 1/2 cup (8 Tbsp; 113g) unsalted butter, softened to room temperature
- 2 cups (240g) confectioners’ sugar
- 2 Tablespoons (30ml) milk
- 1 and 1/4 teaspoons peppermint extract*
- Optional: 1 drop liquid or gel green food coloring
Chocolate Layer
- 1/2 cup (8 Tbsp; 113g) unsalted butter
- 1 heaping cup (around 200g) semi-sweet chocolate chips
Instructions
- Melt the Brownie Base: In a medium saucepan over medium heat, melt the butter and coarsely chopped semi-sweet chocolate while stirring constantly for about 5 minutes until smooth. Alternatively, melt in the microwave in 20-second increments, stirring after each until fully melted. Remove from heat and allow to cool for 10 minutes.
- Prepare the Baking Pan and Batter: Adjust the oven rack to the lower third position and preheat to 350°F (177°C). Line a 9×13-inch baking pan with parchment paper, ensuring an overhang for easy lifting later. In a large bowl, whisk the granulated and brown sugars into the slightly cooled chocolate mixture. Add eggs one at a time, whisking well after each addition. Stir in vanilla extract thoroughly.
- Add Dry Ingredients and Bake: Gently fold in the salt, all-purpose flour, and cocoa powder until just combined. Pour the batter into the prepared pan and bake for 35-36 minutes. Use the toothpick test starting at 30 minutes: a toothpick inserted should come out with only a few moist crumbs. Once done, let the brownies cool completely in the pan on a wire rack.
- Make the Mint Frosting: Using a mixer fitted with a paddle attachment, beat the softened butter on medium speed until smooth and creamy (about 2 minutes). Gradually add confectioners’ sugar and milk, mixing on low speed for 2 minutes, then increase to high speed and beat for 1 more minute. Stir in peppermint extract and optional green food coloring, then beat on high speed for 1 minute until fully incorporated and fluffy. Adjust flavor by adding extra peppermint extract if desired.
- Frost the Brownies: Lift the cooled brownies out of the pan using the parchment paper overhang and set on a baking sheet. Spread the mint frosting evenly over the top. Refrigerate the frosted brownies for at least 1 hour, up to 4 hours, to allow the frosting to set and firm up.
- Prepare the Chocolate Topping: Melt the butter and semi-sweet chocolate chips together in a medium saucepan over medium heat, stirring constantly for about 5 minutes until smooth. Alternatively, melt in the microwave in 20-second increments, stirring after each. Pour the melted chocolate evenly over the chilled mint frosting layer and gently spread with a knife or offset spatula to cover.
- Chill and Set: Return the brownies on the baking sheet to the refrigerator and chill for at least 1 hour or up to overnight to allow the chocolate topping to fully set.
- Cut and Serve: Remove brownies from refrigerator and cut into squares using a very sharp large knife for clean cuts. For best results, make quick cuts and wipe the knife clean between each cut. Brownies can be served at room temperature for a few hours. Store any leftovers tightly covered in the refrigerator for up to 5 days.
Notes
- Ensure eggs are at room temperature for better batter consistency.
- Use parchment paper with overhang for easy removal of brownies from the pan.
- For a stronger mint flavor, add extra peppermint extract to the frosting gradually.
- Allow each layer to cool and set properly before adding the next to avoid melting or mixing.
- Store brownies refrigerated to maintain freshness and texture.
- Optional green food coloring enhances visual appeal but can be omitted without affecting flavor.
- Be cautious with oven baking time as ovens vary; use toothpick test as a guide.
