This Oreo brownie cookie recipe brings together the richness of fudgy brownies with the crunch and creaminess of Oreo cookies for a truly indulgent treat. Perfect for any time you crave a comforting dessert with a chocolatey punch and a playful twist.
I first made these cookies during a casual weekend gathering and was surprised how fast they disappeared. They quickly earned a permanent spot in my recipe collection for their ease and crowd-pleasing taste.
Ingredients You Need
- Cup of butter: for that luscious, moist base. Use unsalted to control the seasoning
- Two cups of sugar: to balance the deep cocoa notes and keep the batter sweet and tender
- Four eggs: to bind everything while lending a bit of richness. Fresh eggs work best
- One teaspoon of vanilla extract: for aromatic depth
- Cup of cocoa powder: which provides intense chocolate flavor. Opt for a good quality unsweetened variety
- Cup of all-purpose flour: as the structure builder. Sift to avoid lumps and ensure a smooth batter
- Half teaspoon of salt: to enhance sweetness and balance flavors. A fine sea salt is ideal
- Half teaspoon of baking powder: for a slight lift and a tender crumb
- Cup of chopped Oreo cookies: that bring a playful texture and familiar twist. Use freshly broken pieces for the best bite
Detailed Cooking Directions
- Preheat Oven and Prepare Pan:
- Start by heating your oven to 350 degrees Fahrenheit or 175 degrees Celsius which ensures even baking. Grease a baking pan well to prevent sticking and to help your cookies have smooth edges.
- Combine Butter and Sugar:
- In a large mixing bowl, melt the butter until just liquid then immediately mix in the sugar. This step creates a rich, creamy base that helps dissolve the sugar for a silky texture.
- Add Eggs and Vanilla:
- Beat in the eggs one at a time along with the vanilla extract mixing thoroughly after each addition. This keeps the batter smooth and incorporates air for a light but dense cookie.
- Incorporate Dry Ingredients:
- Sift together cocoa powder, flour, salt, and baking powder before stirring into the wet mixture gently until just combined. Avoid overmixing as this can make the cookies tough.
- Fold in Oreo Pieces:
- Carefully fold in the chopped Oreo cookies ensuring they are evenly distributed without breaking down too much. These bites will add surprise crunch and creamy bits throughout.
- Bake and Cool:
- Pour the batter into the prepared pan and spread evenly. Bake for 25 to 30 minutes checking at 25 minutes to avoid overbaking as a slightly underdone center creates a fudgier texture. Let the cookies cool completely before cutting into squares for the cleanest slices.

One of my favorite touches is sprinkling a tiny pinch of sea salt on top before baking. It brings out the chocolate and Oreo flavors in a wonderful way. These cookies remind me of lazy afternoons spent baking with family and sharing warm treats fresh from the oven.
Smart Storage Tips
Store the brownie cookies in an airtight container at room temperature to keep their softness and flavor intact for up to three days. For longer storage, freeze the slices separated by parchment paper and thaw at room temperature when ready to enjoy. Avoid refrigerating as it tends to dry out the texture but works well if you like your chocolate extra firm.
Ingredient Variations
Swap Oreos for any sandwich cookies like peanut butter or mint for a unique twist. Add chopped nuts such as walnuts or pecans for extra crunch and a nutty flavor contrast. Mix in mini chocolate chips or white chocolate chunks for more decadent chocolate layers.
Perfect Pairing Ideas
Serve with a scoop of vanilla ice cream for a classic combination of warm and cold delights. A glass of cold milk is a simple and timeless pairing that balances the richness of the cookies. For adults, try a cup of strong black coffee or espresso which cuts through the sweetness beautifully.

These Oreo brownie cookies perfectly blend nostalgic flavors with rich chocolate indulgence. Baking them always feels like a small celebration and makes any day feel a bit sweeter.
