Ingredients
- 1/2 cup unsalted butter
- 6 ounces baking dark chocolate
- 1 1/4 cups white granulated sugar
- 1 cup all-purpose flour
- 2 large eggs
- 2 1/2 cups powdered sugar (or more)
- 4 ounces cream cheese (softened to room temperature)
- 4 tablespoons unsalted butter (softened to room temperature)
- 1/2 teaspoon peppermint extract
- Gel mint green food coloring (a few drops)
- 2 ounces dark baking chocolate (melted)
Instructions
- Step 1: Preheat your oven to 350°F. Line an 8-inch square baking pan with aluminum foil, extending the foil over two opposite sides to form handles. Grease the foil lightly with some batter or baking spray and set aside.
- Step 2: In a medium saucepan over medium heat, melt the 1/2 cup unsalted butter and 6 ounces of dark chocolate, stirring continuously until the mixture is smooth.
- Step 3: Remove the saucepan from heat. Stir in the granulated sugar, flour, and eggs until everything is well combined and smooth.
- Step 4: Pour and spread the brownie batter evenly into the prepared pan.
- Step 5: Bake for 25 to 30 minutes, or until the brownies just start to pull away from the sides of the pan. Let them cool completely in the pan.
- Step 6: For the topping, combine the powdered sugar, softened cream cheese, softened butter, peppermint extract, and gel food coloring in a large bowl. Beat at medium speed until creamy and smooth.
- Step 7: Spread the mint frosting evenly over the cooled brownies.
- Step 8: Melt the remaining 2 ounces of dark chocolate and drizzle it over the frosted brownies for a decorative finish.
- Step 9: Chill the brownies in the refrigerator for a few hours until the topping is firm.
- Step 10: Using the foil handles, lift the brownies out of the pan and cut into squares to serve.
Tips & Variations
- Use gel food coloring sparingly to avoid thinning out the frosting.
- For extra texture, sprinkle crushed peppermint candies over the chocolate drizzle before chilling.
- Replace peppermint extract with spearmint for a milder mint flavor.

- If the frosting is too thick, add a teaspoon of milk to loosen it slightly.
- Use high-quality dark chocolate for a richer brownie base.
- To store, keep brownies refrigerated in an airtight container for up to 4 days.
- Allow brownies to come to room temperature before serving for the best texture and flavor.
