Oreo brownies combine a rich chocolate brownie base with a thick Oreo cookie layer baked on top. They're dense, soft in the center, and easy to slice once cooled.
If you want something a little different from a basic brownie, this recipe adds chopped Oreos and white chocolate for extra texture and flavor without making the process complicated. The texture stays soft in the center with slightly crisp edges, making them easy to serve for parties or holidays.
Why These Oreo Brownies Work
- Fudgy brownie base with deep chocolate flavor
- Chopped Oreo cookies in every layer
- White chocolate adds richness
- Bakes in one 9x13-inch pan
- Easy to slice once fully cooled
These are not cakey brownies. The texture stays dense and soft in the center with slightly crisp edges.
If you enjoy Oreo desserts, this Cookies and Cream Cheesecake is another rich, layered option worth trying.

How to Make Oreo Brownies
- Preheat oven to 350°F. Spray a 9x13-inch pan with cooking spray or line with parchment paper.
- In a large bowl, whisk melted butter and sugar. Add eggs and vanilla and mix until smooth.
- Stir together cocoa powder, flour, and salt. Add to the bowl and mix until just combined. Fold in chocolate chips. Spread evenly into the prepared pan.
- Bake for 20-25 minutes, until the center is just set.
- Melt white chocolate chips and butter in a microwave-safe bowl in 30-second intervals, stirring until smooth. Let cool slightly.
- In a separate bowl, beat eggs with sugar and vanilla. Stir in the melted chocolate mixture. Add flour and salt and mix until combined. Fold in chopped Oreos.
- Spoon the Oreo mixture over the partially baked brownies and gently spread.
- Bake an additional 25-30 minutes, until the top is set and lightly golden around the edges.
- Cool completely before cutting into squares.
Tips for Best Results
- Do not overbake. The center should still feel slightly soft when removed from the oven.
- Let brownies cool completely before slicing for clean cuts.
- For deeper chocolate flavor, add ½ teaspoon espresso powder to the brownie batter.
- Regular Oreos work best, but peanut butter Oreos can be used for variation.
Storage
Store in an airtight container at room temperature for 2-3 days.
For longer storage, wrap tightly in plastic wrap and refrigerate up to 5 days.
These also freeze well once fully cooled.
