Calories 293 kcal


  • 3/4 cup plus 2 T. all-purpose flour
  • 1/4 tsp. salt
  • 4 oz (1 stick) unsalted butter, chopped
  • 1 oz unsweetened chocolate finely chopped
  • 7 oz bittersweet chocolate finely chopped
  • 2 large eggs
  • 1 cup sugar
  • 12 mint Oreos (or any flavor you like)


  • Place a rack in the middle of the oven and preheat to 350 degrees F. Grease an 8-by-8 inch square baking dish with pan spray. Sift together the flour and salt and set aside.
  • Melt the butter, unsweetened chocolate, and bittersweet chocolate in a microwave-safe bowl at 50 percent power for about 2 minutes or in a heatproof bowl set over a saucepan of simmering water. Stir with a rubber spatula until the mixture is smooth. Allow to cool to tepid (90 degrees F).
  • In the bowl of a stand mixer fitted with the paddle attachment, beat together the eggs and sugar until fluffy. Gently beat in the butter and chocolate. Using a rubber spatula, fold in the flour.
  • Scrape half the batter into the prepared baking dish. Line the Oreos on top to evenly cover the batter (you can cut cookies in half in order to make them all fit). Top with the remaining batter and smooth out the top. Bake, rotating from front to back halfway through, for 25 to 30 minutes, until slightly firm to the touch and a crust has formed on top. A toothpick will NOT come out clean.
  • Allow to cool in the pan on a wire rack to room temperature. Cut into squares.
