Halloween Oreo Stuffed Brownies Recipe
Introduction
Halloween Oreo stuffed brownies are a deliciously decadent treat that combines rich chocolate brownies with a surprise Oreo center. Perfect for spooky gatherings or any time you want a fun twist on classic brownies.

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 the oven to 350°F (175°C) and line an 8×8 inch baking pan with parchment paper. Set aside.
- Step 2: In a microwave-safe bowl, combine the butter, vegetable oil, granulated sugar, and brown sugar. Melt together in 30-second intervals, stirring between each, until fully melted. Then microwave for an additional 1 minute and stir vigorously to fully dissolve the sugar. Using a hand or stand mixer at this stage is ideal.
- Step 3: Whisk in the cold eggs one at a time, then add the vanilla extract. Mix until the batter pulls slightly from the sides of the bowl.
- Step 4: Add the flour, cocoa powder, and salt. Fold gently just until combined, being careful not to overmix.
- Step 5: Pour half of the batter into the prepared pan and spread it evenly.
- Step 6: Arrange the 15 Oreos in a single layer over the batter, placing them in the center to create a buried cookie surprise.
- Step 7: Spread the remaining brownie batter over the Oreos, covering them completely. Sprinkle the 5 crushed Oreos on top for extra crunch and decoration.
- Step 8: Bake in the preheated oven for about 30 minutes. The brownies should be set at the edges but slightly soft in the middle.
- Step 9: Allow the brownies to cool completely on a wire rack before slicing to achieve clean, square pieces with a crinkly top.
Tips & Variations
- For a richer flavor, use melted dark chocolate instead of cocoa powder.
- Try swapping Oreos for other sandwich cookies for variety or add a handful of nuts for extra texture.
- Ensure eggs are cold to help create a fudgy brownie texture.
- Use parchment paper with some overhang to easily lift the brownies from the pan once cooled.
Storage
Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week or freeze for up to 3 months. Reheat chilled brownies briefly in the microwave to soften before serving.

FAQs
Can I use room temperature eggs instead of cold eggs?
Cold eggs help create a fudgier texture, but room temperature eggs will still work if necessary. Just avoid overmixing the batter.
Do I have to crush Oreos for the topping?
Crushed Oreos on top add a nice texture and decorative touch, but you can omit them or use whole Oreos if you prefer.

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 eggs (cold)
- 1 tsp vanilla extract
- 1/2 tsp salt
- 1/2 cup all-purpose flour
Oreo Center
- 15 Oreos (for stuffing)
- 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.
- Melt fats and sugars: In a microwave-safe bowl, combine butter, vegetable oil, granulated sugar, and brown sugar. Microwave in 30-second intervals, stirring between each, until fully melted. Then microwave for an additional 1 minute and stir vigorously to fully dissolve the sugar, ensuring a smooth batter. Using a hand or stand mixer is recommended for best texture.
- Add eggs and vanilla: Whisk in the eggs one at a time to fully incorporate, then add the vanilla extract. The batter should be thick enough to pull away slightly from the bowl edges.
- Incorporate dry ingredients: Add the cocoa powder, flour, and salt to the wet mixture. Fold gently until just combined to maintain fudginess without overmixing.
- Layer batter and Oreos: Pour half of the brownie batter into the prepared pan and spread evenly. Arrange the 15 Oreos in a layer centered on top of the batter.
- Top with remaining batter: Spoon and spread the remaining batter over the Oreos, ensuring they are fully covered.
- Add crushed Oreos and bake: Sprinkle the 5 crushed Oreos evenly over the top for added texture. Bake in the preheated oven for 30 minutes, or until the edges are set and a toothpick inserted near the edges comes out with moist crumbs.
- Cool and slice: Allow the brownies to cool completely on a wire rack before lifting out of the pan using the parchment overhang. Slice into squares for serving, revealing the Oreo-stuffed center.
Notes
- For fudgier brownies, avoid overmixing the batter after adding the flour.
- Using cold eggs helps in achieving a thick batter consistency.

- Allow the brownies to cool fully before slicing to ensure clean cuts and prevent crumbling.
