A triple-layer dessert combining a soft chocolate chip cookie base, a crunchy Oreo center, and a rich, fudgy brownie topping for an irresistible treat.
Preheat your oven to 350°F (175°C) and line a baking pan with parchment paper. In a mixing bowl, cream together unsalted butter, granulated sugar, and brown sugar until light and fluffy. Add one large egg and vanilla extract, then mix in all-purpose flour, baking soda, and salt. Fold in chocolate chips and press the dough evenly into the pan.
Place 12 whole Oreo cookies in a single layer on top of the cookie dough, ensuring they do not overlap.
In a separate bowl, melt unsalted butter and whisk in granulated sugar and cocoa powder until smooth. Allow the mixture to cool slightly, then mix in 2 large eggs and vanilla extract, and finally fold in all-purpose flour and salt.
Pour the brownie batter evenly over the Oreo layer, using a spatula to smooth the top and ensure full coverage.
Bake in a preheated oven for 30 to 35 minutes until a toothpick inserted in the center comes out with a few moist crumbs. Let cool completely before slicing.
Notes
