Step‑by‑Step Instructions for Fudgy Halloween Oreo Stuffed Brownies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) and lining an 8×8 inch baking pan with parchment paper. This prepares the pan for the fudgy brownie batter, ensuring easy removal once baked. Smooth out the parchment to fit the corners, guaranteeing every delicious layer of your Halloween Oreo brownies will bake evenly and release effortlessly.
Step 2: Melt the Butters and Sugars
In a microwave-safe bowl, combine butter, vegetable oil, granulated sugar, and brown sugar. Heat this mixture in 30-second intervals, stirring well between each session until fully melted, which usually takes about 1 to 2 minutes. The goal is to create a smooth, glossy mixture where the sugars dissolve completely, leaving no grainy texture.
Step 3: Vigorously Mix the Batter
Once melted, microwave the mixture for an additional minute while stirring vigorously to ensure the sugars dissolve completely. This creates a rich, syrupy base for your brownies. The mixture should be shiny and sticky, indicating that the sugars are properly incorporated, which will contribute to the fudgy texture of your Halloween Oreo brownies.
Step 4: Incorporate Eggs and Vanilla
Next, add eggs to the sugary mixture, whisking in one egg at a time until fully combined. Follow this with the vanilla extract, stirring until the batter is cohesive and smooth. This step adds depth to your brownie batter, enriching the flavors and helping achieve that classic fudgy texture that’s perfect for these Halloween Oreo brownies.
Step 5: Combine Dry Ingredients
Gently fold in the all-purpose flour, cocoa powder, and salt into the wet mixture using a spatula. Be careful not to overmix; simply combine until you see no streaks of flour—this will help keep your brownies soft and chewy. The chocolatey aroma will fill your kitchen, making it hard to resist the enticing fudgy goodness of the batter.
Step 6: Layer the Brownie Batter
Pour half of the brownie batter into the prepared baking pan, using a spatula to spread it evenly across the bottom. This layer forms the base for your treat, and it should be thick enough to support the Oreos without them sinking. The deep, dark chocolate hue is visually appetizing and promises a delicious bite ahead.
Step 7: Add Halloween Oreos
Place your Halloween Oreos in a single layer over the brownie batter, spacing them evenly. This will ensure each brownie piece has a delicious surprise in the middle. Once the Oreos are laid out, carefully spoon the remaining brownie batter on top, spreading it gently to cover the cookies without displacing them.
Step 8: Bake to Perfection
Sprinkle additional crushed Halloween Oreos on top for a festive touch, then transfer the baking pan to the preheated oven. Bake for approximately 30 minutes, or until the edges are set and a toothpick inserted into the center comes out with a few moist crumbs. The brownies will appear slightly puffed and cracked on the surface, signaling they are ready to cool.
Step 9: Cool for Ideal Slicing
Once baked, take the brownies out of the oven and let them cool completely in the pan on a wire rack. For cleaner edges, aim for at least 8 hours of cooling time; this step is crucial for achieving those perfect brownie squares that will showcase the delightful layers of your Halloween Oreo brownies when sliced.

Halloween Oreo Brownies Recipe FAQs
What type of Halloween Oreos should I use?

How should I store my Halloween Oreo brownies?

When you’re ready to enjoy, simply thaw them in the fridge overnight, or pop them in the microwave for a few seconds to reinvigorate their gooeyness.
What do I do if my brownies turn out too dense?
If your brownies end up denser than expected, it’s often due to overmixing the batter or underbaking them. To avoid this in the future, mix the batter just until the flour is combined, and ensure you’re checking for moist crumbs with the toothpick test before taking them out of the oven. Remember, a few streaks of flour are okay!
Are there any dietary considerations I should keep in mind?
Yes, those with allergies should note that this recipe contains gluten, eggs, and dairy. For a gluten-free version, you can swap all-purpose flour with a gluten-free baking blend. Additionally, if anyone has a dairy allergy, margarine can be used instead of butter. Always check ingredient labels for potential allergens.
How can I ensure my brownies have clean edges when cutting?
For perfectly squared brownies, allow them to cool completely—ideally for about 8 hours—as this firms them up. When cutting, use a sharp knife and dip it in warm water before slicing. This creates smooth cuts without dragging, making for a beautiful presentation of your Halloween Oreo brownies!
