Ingredients

Scale
  • 1 cup (226g) unsalted butter, melted
  • 2 cups (400g) granulated sugar
  • 4 large eggs, room temperature
  • 1 tsp pure vanilla extract
  • 1 cup (125g) all-purpose flour
  • ¾ cup (65g) unsweetened cocoa powder
  • ½ tsp salt
  • ½ tsp baking powder
  • 20 Mint Oreos, crushed roughly
  • 1 tsp peppermint extract
  • 1 cup (175g) semi-sweet chocolate chips
  • ½ cup (120ml) heavy cream
  • Optional: Green food coloring

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper.
  2. In a large bowl, whisk the melted butter and granulated sugar until well combined and slightly glossy, about 2 minutes. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  3. In a separate bowl, sift together the all-purpose flour, cocoa powder, salt, and baking powder. Gently fold the dry ingredients into the wet mixture using a rubber spatula until just combined—avoid overmixing.
  4. Fold in half of the crushed Mint Oreos and the peppermint extract into the batter, distributing evenly but gently.
  5. Pour batter into the prepared pan and spread evenly. Sprinkle the remaining crushed Oreos on top, pressing them lightly into the batter.
  6. Bake for 30-35 minutes. Use a toothpick inserted in the center to check doneness—it should come out with a few moist crumbs but not wet batter.
  7. While brownies bake, warm the heavy cream in a small saucepan over low heat until it just starts to simmer. Remove from heat and add chocolate chips, stirring until smooth and glossy. Add green food coloring if desired.
  8. Once brownies are baked, remove from oven and pour the warm fudge topping evenly over them. Spread gently if needed. Let set at room temperature for about 30 minutes or refrigerate for quicker setting.
  9. Once set, cut into squares with a sharp knife, wiping the knife between slices. Serve at room temperature or slightly chilled.

Notes

Use melted butter for a fudgy texture and avoid overmixing the batter to prevent cakey brownies. Start with a small amount of peppermint extract to avoid overpowering mint flavor. Let brownies cool fully before cutting to keep fudge topping intact. For dairy-free or gluten-free versions, substitute ingredients as suggested.
