Mint Chocolate Oreo Fudge Brownies for St. Patrick's Day

Ultimate Mint Chocolate Oreo Fudge Brownies


Mint Chocolate Oreo Brownies

  • 6 oz bittersweet chocolate (60%), chopped

  • ¾ cup unsalted butter, cubed

  • 1¼ cup granulated sugar

  • 3 large eggs, room temperature

  • 2 tsp pure mint extract (not peppermint)

  • ¾ cup all-purpose flour

  • ¼ cup unsweetened cocoa powder, sifted

  • ½ tsp salt

  • 16 Mint Oreo cookies

Mint Chocolate Oreo Fudge

  • 1 (14 oz) can sweetened condensed milk

  • 24 oz white chocolate chips

  • 1½ tsp pure mint extract

Mint Chocolate Ganache

  1. Preheat oven to 350°F. Line a 9x9-inch square baking pan with aluminum foil or parchment paper, leaving about 2-inches overhanging on the sides and spray with non-stick spray. Set aside.

  2. Place the chopped chocolate and cubed butter in a large bowl over a saucepan of simmering water. Heat on medium-low, stirring constantly until the butter and chocolate are fully melted and combined, about 3-4 minutes.

  3. Remove the bowl from the heat and immediately add the sugar, whisking until the sugar is dissolved and the mixture is smooth. Allow the mixture to cool for a few minutes before proceeding. (This is to prevent the eggs from curdling.)

  4. Add the eggs and mint extract and slowly whisk until combined. Do not overmix. Add the flour, cocoa, and salt and stir with a rubber spatula until incorporated.

  5. Pour half of the batter into the prepared pan and place a layer of Oreos on top. Pour the rest of the batter on top of the Oreos and spread into an even layer ensuring the Oreos are completely covered. Bake for 25-30 minutes, or until a toothpick inserted into the brownie comes out with a few moist crumbs. Allow to cool completely in the pan on a wire rack.

  1. Add the sweetened condensed milk and white chocolate chips to a medium bowl over a saucepan of simmering water. Heat on medium-low, stirring constantly until the chocolate is fully melted and the mixture is combined and smooth. Remove from the heat and stir in the mint extract and green food coloring. Then gently fold in the chopped Oreos.

  2. Spread over the cooled brownies and place in the refrigerator to set, about 2 hours.

Mint Chocolate Ganache

  1. In a microwave safe bowl, add the chocolate chips, heavy whipping cream, and mint extract. Microwave in 30 second intervals for about 1 minute until melted. Stir slowly until the mixture comes together to form a thick, smooth ganache.

  2. Pour the ganache over the fudge and spread into an even layer. Return to the refrigerator to set for at least 30 minutes.

  3. Once set, lift the brownies out of the pan and slice into squares. Enjoy!
