The Best Fudgy Oreo Brownies Recipe
Introduction
If you’re craving rich, fudgy brownies with a fun twist, these Oreo brownies are sure to satisfy. Combining intense chocolate flavor with chunks of Oreo cookies creates a decadent treat perfect for any chocolate lover.

Ingredients
- 2/3 cup butter
- 1/4 cup vegetable oil
- 1 cup granulated sugar
- 1/3 cup brown sugar
- 2/3 cup cocoa powder
- 2 eggs (cold)
- 1 tsp vanilla extract
- 1/2 tsp salt
- 1/2 cup all-purpose flour
- 15 Oreos (extra 5 for topping)
Instructions
- Step 1: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper and set it aside.
- Step 2: In a microwave-safe bowl, melt the butter, vegetable oil, granulated sugar, brown sugar, and cocoa powder together. Heat in 30-second intervals, stirring between each until fully melted. Then microwave for an additional minute and stir vigorously to fully dissolve the sugars.
- Step 3: Whisk in the eggs one at a time until combined, then add the vanilla extract. The batter should be thick enough to pull away from the sides of the bowl slightly.
- Step 4: Add the flour and salt, folding gently just until the ingredients are combined to avoid overmixing.
- Step 5: Pour half of the brownie batter into the prepared pan, spreading it evenly.
- Step 6: Arrange 15 Oreo cookies in the center of the batter.
- Step 7: Cover the Oreos with the remaining batter, spreading to fully cover them.
- Step 8: Sprinkle the top with 5 crushed Oreos and bake in the preheated oven for 30 minutes.
- Step 9: Let the brownies cool completely on a wire rack before slicing to achieve perfect, fudgy squares with a crinkly top.
Tips & Variations
- For extra fudginess, slightly underbake your brownies by 2–3 minutes and allow them to set completely as they cool.
- Try using double-stuffed Oreos for an even richer cookie center.
- Swap vegetable oil for melted coconut oil for a subtle, nutty flavor.
- Add a pinch of espresso powder to the batter to enhance the chocolate depth.
Storage
Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, keep them refrigerated for up to a week or freeze for up to 3 months. Reheat gently in the microwave for 10–15 seconds to regain their fudgy texture.

FAQs
Can I use a different type of cookie instead of Oreos?
Yes, feel free to substitute Oreos with other sandwich cookies or even chunks of chocolate chip cookies for a new flavor twist.
Do I need to use cold eggs?
Cold eggs help the batter hold together better and create a fudgier texture, but if you forget to chill them, room temperature eggs will still work fine.

Ingredients
Brownie Batter
- 2/3 cup butter
- 1/4 cup vegetable oil
- 1 cup granulated sugar
- 1/3 cup brown sugar
- 2/3 cup cocoa powder
- 2 cold eggs
- 1 tsp vanilla extract
- 1/2 tsp salt
- 1/2 cup all-purpose flour
Oreos
- 15 Oreos (for inside batter)
- 5 Oreos (crushed for topping)
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, allowing some overhang for easy removal later, and set aside.
- Melt Butter and Mix Sugars: In a microwave-safe bowl, combine the butter, vegetable oil, granulated sugar, brown sugar, and cocoa powder. Microwave in 30-second intervals, stirring well after each, until everything is melted and combined. Once melted, microwave for an additional 1 minute and stir vigorously to ensure the sugars dissolve completely.
- Add Eggs and Vanilla: Whisk in the cold eggs one at a time into the chocolate mixture, fully incorporating each before adding the next. Then stir in the vanilla extract. The batter should pull away from the sides of the bowl slightly when mixed properly.
- Incorporate Dry Ingredients: Add in the all-purpose flour and salt. Gently fold the dry ingredients into the wet until just combined, being careful not to overmix for a fudgy texture.
- Layer Batter and Oreos: Pour half of the brownie batter into the prepared pan and spread evenly. Arrange the 15 whole Oreos in the center of this batter layer in a single layer, as shown in the photo.
- Top with Remaining Batter and Crushed Oreos: Pour the remaining brownie batter over the Oreos, spreading to cover completely. Sprinkle the 5 crushed Oreos evenly over the top for added crunch and decoration.
- Bake: Place the pan in the preheated oven and bake for 30 minutes. The brownies should be set but fudgy when done; a toothpick inserted will come out with a few moist crumbs.
- Cool and Slice: Remove the brownies from the oven and let them cool completely on a wire rack. Once cooled, use the parchment paper overhang to lift the brownies from the pan and slice into squares for clean, crinkle-top pieces.
Notes
- Make sure the eggs are cold when adding to the batter to help maintain the fudgy texture.
- Do not overmix once the flour is added; overmixing can make brownies cakey instead of fudgy.
- Using parchment paper makes removal and slicing easier and cleaner.
- For even fudgier results, slightly underbake and allow residual heat to finish cooking.
- Storage: Keep brownies in an airtight container at room temperature for up to 3 days or refrigerate for up to 5 days.
