Ingredients Breakdown
Here is the complete list of ingredients needed for one 8×8-inch pan of Halloween Oreo Stuffed Brownies, serving 16. Every measurement is exact to ensure perfect results.
Brownie Base
- 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 teaspoon vanilla extract
- 1/2 teaspoon salt
- 1/2 cup all-purpose flour
Oreo Layer
- 15 Oreos for the center
- 5 Oreos, crushed, for topping
Tools & Equipment Needed
You don’t need a lot of specialized equipment to make these brownies:
- Measuring cups and spoons
- Microwave-safe bowl
- Hand mixer or stand mixer (optional, but helps with sugar melting)
- Rubber spatula
- 8×8-inch baking pan
- Parchment paper (for easy removal)
- Wire cooling rack
- Knife or brownie cutter
Step-by-Step Instructions
Follow these steps carefully for fudgy, perfectly layered Oreo brownies.
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving extra overhang on the sides for easy removal of the brownies. Set aside.
Step 2: Melt Butter and Sugar
In a microwave-safe bowl, combine:
- 2/3 cup butter
- 1/4 cup vegetable oil
- 1 cup granulated sugar
- 1/3 cup brown sugar
Microwave in 30-second intervals, stirring between each session until melted. Then, microwave for an additional 1 minute and stir vigorously to ensure the sugar fully dissolves. Using a hand mixer or stand mixer here will make this step easier and ensure a smooth, glossy batter.
Step 3: Add Eggs and Vanilla
Whisk in the 2 cold eggs, one at a time, making sure each is fully incorporated before adding the next. Then, add 1 teaspoon vanilla extract. The batter should pull slightly from the sides of the bowl when mixed correctly — a sign that it’s smooth and ready for the dry ingredients.
Step 4: Fold in Dry Ingredients
Add:
- 1/2 teaspoon salt
- 1/2 cup all-purpose flour
- 2/3 cup cocoa powder
Fold gently until just combined. Avoid overmixing to maintain a fudgy texture. The batter should be thick but still spreadable.
Step 5: Assemble the Brownie Layers
- Pour half of the brownie batter into the prepared 8×8-inch pan. Spread evenly with a spatula.
- Place 15 Oreos in a single layer over the brownie batter.
- Pour the remaining batter over the Oreo layer, spreading carefully to cover all cookies.
- Sprinkle the 5 crushed Oreos over the top for an added decorative and crunchy finish.
Step 6: Bake
Bake in the preheated oven for 30 minutes. The top should look set, and a toothpick inserted near the center will come out with a few moist crumbs.
Step 7: Cool and Slice
Allow the brownies to cool completely on a wire rack before slicing. This ensures clean cuts and a perfect crinkle-top slice every time. Use the parchment overhang to lift the brownies from the pan. Slice into 16 squares and serve.
Tips & Variations
- Dairy-free version: Substitute butter with coconut oil and ensure Oreos are dairy-free (they typically are in the US).
- Extra chocolate: Fold in 1/4 cup chocolate chips for an even richer brownie.
- Nutty crunch: Add 1/2 cup chopped walnuts or pecans into the batter.
- Mini brownie bites: Pour batter into a lined muffin tin and bake for 18–20 minutes for Oreo-stuffed brownie bites.
- Spooky toppings: Use Halloween-themed sprinkles or drizzle with white chocolate to enhance the festive look.
Flavor Profile
These brownies are:
- Fudgy and rich: The perfect chocolate depth from butter, cocoa powder, and sugar.
- Chewy with a crunch: Whole Oreos in the center add texture, and the crushed Oreos on top provide a light crunch.
- Sweet but balanced: The combination of granulated and brown sugar gives sweetness with a hint of caramel flavor.
- Chocolate-forward: Cocoa powder delivers intense chocolate flavor without bitterness.
