Ingredients

• ▢7 tablespoons (98 g) unsalted butter, room temperature
• ▢¾ cup (150 g) light brown sugar
• ▢2 tablespoons granulated sugar
• ▢1 large egg, room temperature
• ▢1 ¼ teaspoon pure vanilla extract
• ▢1 cup plus 2 tablespoons (140 g) unbleached all-purpose flour
• ▢½ teaspoon baking soda
• ▢½ teaspoon salt
• ▢1 cup semi-sweet chocolate chips

Brownie Layer

• ▢5 oz. semisweet chocolate chips
• ▢6 tablespoons (85 g) unsalted butter, cold and cut into cubes
• ▢2 ¼ tablespoons unsweetened cocoa powder
• ▢2 large eggs, room temperature
• ▢1 cup (200 g) granulated sugar
• ▢1 ½ teaspoons pure vanilla extract
• ▢½ teaspoon salt
• ▢¾ cup (95 g) unbleached all-purpose flour
• ▢16 regular or double stuff oreos

Step-by-Step Instructions

1. Preheat your oven to 350° F. Spray an 8×8-inch baking pan with nonstick cooking spray, line it with foil or parchment paper, then spray again to ensure easy removal. Set the pan aside.
2. In a medium bowl, whisk together the flour, salt, and baking soda for the cookie dough layer. Set this dry mixture aside.
3. Using a stand mixer fitted with a paddle attachment or a hand mixer, cream together the butter, light brown sugar, and granulated sugar until the mixture is light and fluffy, about 3 minutes.
4. Beat in the egg and vanilla extract, scraping down the sides of the bowl to ensure even mixing.
5. Slowly add the flour mixture to the wet ingredients and mix just until combined. Stir in the chocolate chips by hand. Set the cookie dough aside or refrigerate briefly if preferred.
6. For the brownie layer, melt the semisweet chocolate chips and cubed butter together using a double boiler or microwave, stirring frequently until smooth. Whisk in the cocoa powder and allow the mixture to cool slightly.
7. Fit your mixer with a whisk attachment. Whisk together the eggs, sugar, vanilla extract, and salt for about 30 seconds, just until combined.
8. Whisk the warm chocolate mixture into the egg mixture until smooth and glossy.
9. Add the flour to the wet ingredients and gently fold with a rubber spatula until fully incorporated. Set aside.
10. Press the cookie dough evenly into the bottom of the prepared pan, forming a compact base layer.
11. Arrange the Oreos in a single layer on top of the cookie dough, fitting as many as possible without overlapping.
12. Slowly pour the brownie batter over the Oreo layer, spreading gently to ensure even coverage.
13. Bake for 35 to 40 minutes. Insert a toothpick into the center: if it comes out clean, the brownies are done; if not, bake for an additional 5 minutes.
14. Allow the brownies to cool completely in the pan before slicing and serving for the cleanest layers.

Expert Tips for Best Results

Letting the chocolate mixture cool slightly before combining it with the eggs helps prevent curdling and keeps the brownie layer smooth. This step is especially important for achieving a consistent texture.

Press the cookie dough firmly into the pan so it forms a stable base that supports the Oreo and brownie layers during baking. Uneven pressure can cause shifting.

Cooling the brownies fully before cutting allows the layers to set properly, giving you clean edges and a more polished presentation.

Use room-temperature eggs for both layers to ensure smoother mixing and better structure in the final bake.

Flavor Variations and Custom Ideas

• Use regular or double stuff Oreos depending on how prominent you want the cookie layer
• Chill the cookie dough slightly before layering for a firmer base
• Cut brownies into smaller squares for dessert trays or gatherings
• Serve slightly warm with milk for a softer texture contrast
• Slice and layer on a dessert platter for easy sharing

Storage and Reheating

Store the brownies in an airtight container at room temperature for up to two days. If your kitchen is warm, refrigeration helps maintain structure.

For longer storage, keep them refrigerated for up to five days. Bring to room temperature before serving for the best texture.

To reheat, warm individual pieces briefly in the microwave for a soft, just-baked feel without overheating the layers.
