Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
Brownie Batter
2/3 cup semisweet chocolate chips
1/4 cup butter
1 egg, at room temperature
1/3 cup granulated sugar
1 teaspoon vanilla extract
1/4 cup gluten-free all-purpose flour (or regular all-purpose flour)
2 tablespoons cocoa powder
1/8 teaspoon sea salt
2 tablespoons chocolate chips
Cookie Dough
1/4 cup butter, melted
1/4 cup brown sugar
2 tablespoons granulated sugar
1 egg
1 teaspoon vanilla extract
3/4 cup gluten-free all-purpose flour (or regular all-purpose flour)
1 teaspoon baking soda
1/8 teaspoon sea salt
4 Oreo-style chocolate sandwich cookies, chopped
Preheat the oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper, leaving an overhang on two sides for easy removal.
Make the brownie batter: Melt the chocolate chips and butter together in 30-second microwave intervals, stirring until smooth. In a bowl, whisk the egg, granulated sugar, and vanilla together, then slowly whisk in the melted chocolate mixture. Add the flour, cocoa powder, and sea salt, mixing just until combined. Fold in the chocolate chips and set aside.
Make the cookie dough: In a separate bowl, whisk the melted butter, brown sugar, and granulated sugar until smooth. Add the egg and vanilla and whisk until creamy. Add the flour, baking soda, and sea salt, stirring until a soft dough forms. Fold in the chopped Oreo cookies.
Assemble: Scoop about 2 tablespoons of cookie dough into the prepared pan, spacing the scoops evenly. Fill the gaps with the brownie batter. Use a spatula to gently press and spread the mixture evenly.
Top with the remaining chopped Oreos, pressing lightly. Cover the pan with foil.
Bake for 15 minutes. Remove the foil and continue baking for 12–17 more minutes, or until a toothpick inserted into the brownie batter comes out with moist crumbs.
Cool in the pan for 10 minutes, then lift out using the parchment and transfer to a cooling rack. Allow to cool completely before slicing.

FAQs
Can I use a boxed brownie mix?
Yes, you can substitute the brownie layer with a boxed mix prepared according to package directions.
Do I need to use whole or crushed Oreos?
Either works—whole chopped cookies offer more texture, while crushed cookies blend more smoothly into the batter.
How do I keep brookies fudgy instead of cakey?
Avoid overmixing and remove them from the oven when a toothpick shows moist crumbs, not a clean finish.
Can I make these gluten-free?
Yes—use gluten-free all-purpose flour and gluten-free chocolate sandwich cookies.
How do I cut brookies cleanly?
Let the brookies cool completely, then use a sharp knife wiped clean between cuts.
Can I double this recipe?
Yes—double all ingredients and use a 9×13-inch baking dish. Baking time may increase slightly.
Can I reduce the sugar?
You can reduce the sugar in both layers by up to 20%, though texture may become slightly less fudgy.
Can I use dark chocolate instead of semisweet?
Absolutely—dark chocolate will add a richer, slightly less sweet flavor.
Should I chill the cookie dough?
Chilling isn’t required, but 10–15 minutes in the fridge can help if your dough feels too soft.
Can I add mix-ins like chocolate chunks?
Yes—additional chocolate or halal-friendly flavor chips can be folded into either layer.
