Ultimate Brownies
The Ultimate Brownies feature three indulgent layers: buttery chocolate chip cookie dough, a middle layer of Oreo cookies, and a rich fudgy brownie topping. Each slice reveals a beautiful stacked cross-section with chewy, creamy, and chocolatey textures in every bite.
Equipment
- 8x8 inch metal baking pan
- Mixing bowls
- Whisk
- Spatula
Ingredients
- 0.5 cup butter, softened (for cookie layer)
- 0.5 cup butter, melted (for brownie layer)
- 1 cup granulated sugar
- 0.75 cup brown sugar
- 3 eggs
- 1 tsp vanilla extract
- 1 cup all-purpose flour (for cookie dough)
- 0.75 cup all-purpose flour (for brownie batter)
- 0.33 cup cocoa powder
- 1 cup chocolate chips
- 16 Oreo cookies
- 0.5 tsp baking soda
- 0.5 tsp sea salt (plus extra for topping)
Instructions
- Preheat oven to 350°F (175°C). Line an 8×8-inch metal baking pan with parchment paper.
- Make the cookie dough by creaming softened butter, brown sugar, and 1/2 cup granulated sugar until smooth. Mix in one egg and vanilla.
- Stir in flour, baking soda, sea salt, and chocolate chips to form a thick cookie dough.
- Press the cookie dough evenly into the bottom of the prepared baking pan.
- Arrange the Oreo cookies in a tight single layer over the cookie dough.
- Prepare the brownie batter by whisking melted butter, remaining sugar, and eggs until smooth. Stir in vanilla, cocoa powder, and remaining flour.
- Pour the brownie batter over the Oreo layer and spread evenly.
- Bake for 30–35 minutes until the top is set but the center remains slightly fudgy.
- Sprinkle with flaky sea salt and allow to cool completely in the pan for about 3 hours before slicing into 16 squares.
Notes
Allow the brownies to cool fully for at least 3 hours before slicing. This resting time helps the layers set properly so you get clean, defined cookie, Oreo, and brownie layers.
