A rich, fudgy brownie dessert made with three delicious layers: a dense chocolate brownie base filled with chopped Mint Oreos, a smooth peppermint cream layer, and a glossy chocolate topping. The combination of deep chocolate and refreshing mint makes these brownies an irresistible treat for holidays, parties, or any time you crave a decadent dessert.
Equipment
- 9 x 13 inch baking pan
- parchment paper or foil for lining the pan
- large mixing bowl
- medium mixing bowl
- electric mixer or whisk
- spatula
- microwave safe bowl
- refrigerator for chilling layers
Ingredients
- 1 cup unsalted butter, melted
- 2 cups granulated sugar
- 1 cup unsweetened cocoa powder
- 4 large eggs
- 1 tbsp vanilla extract
- 1 cup all purpose flour
- 1 tsp salt
- 18 Mint Oreo cookies, roughly chopped
- 1/2 cup unsalted butter, softened
- 2 cups powdered sugar
- 1 tbsp milk
- 1/2 tsp peppermint extract
- 1 drop green food coloring (optional)
- 1 cup semisweet chocolate chips
- 2 tbsp butter
Instructions
- Preheat the oven to 350°F (175°C). Line a 9 x 13 inch baking pan with parchment paper or foil and lightly grease it to make removing the brownies easier later.
- In a large bowl combine the melted butter, granulated sugar, and cocoa powder. Stir until smooth and glossy. Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract. Gently mix in the flour and salt until just combined, then fold in the chopped Mint Oreos.
- Spread the brownie batter evenly into the prepared pan. Bake for about 25 minutes or until the center is just set and still slightly soft. Allow the brownies to cool completely before adding the next layer.
- In a medium bowl beat the softened butter and powdered sugar until smooth. Add the milk and peppermint extract and continue mixing until creamy. Stir in a small drop of green food coloring if desired. Spread the mint mixture evenly over the cooled brownie layer and refrigerate for about 30 minutes until firm.
- In a microwave-safe bowl melt the chocolate chips and butter together in short bursts, stirring every 20 seconds until smooth. Pour the melted chocolate over the mint layer and spread gently to cover the surface.
- Return the pan to the refrigerator for about 1 hour until the chocolate topping sets. Once fully chilled, lift the brownies from the pan and slice into squares using a sharp knife, wiping the blade between cuts for neat layers.
Notes
For the best texture, allow the brownies to cool completely before adding the mint layer so it doesn’t melt. Chill the brownies before slicing to achieve clean, beautiful layers. Use high-quality cocoa powder for deeper chocolate flavor. If Mint Oreos are unavailable, regular Oreos can be used and you can slightly increase the peppermint extract for extra mint flavor.
