Ingredients
Brownie Layer
- 1 cup unsalted butter, melted
- 2 cups granulated sugar
- 1 cup packed brown sugar
- 4 large eggs
- 1 tablespoon vanilla extract
- 1 cup unsweetened Dutch-processed cocoa powder
- 1 cup all-purpose flour
- ½ teaspoon baking powder
- ½ teaspoon salt
- 1 cup semi-sweet chocolate chips (optional)
Oreo Layer
- 20–24 Halloween Oreos or classic Oreos
Festive Topping
- 1½ cups white chocolate or white candy melts
- Orange food coloring or orange candy melts
- Purple food coloring or purple candy melts
- Halloween-themed sprinkles
- Candy eyeballs (optional)
- Crushed Oreos for garnish (optional)
Step-by-Step Instructions
1. Preheat and Prepare the Pan
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper, leaving an overhang on the sides for easy removal. Lightly grease the parchment paper.
2. Make the Brownie Batter
In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth and glossy. Add the eggs one at a time, whisking well after each addition. Stir in the vanilla extract.
In a separate bowl, sift together the cocoa powder, flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing just until combined. Fold in chocolate chips if using — do not overmix.
3. Assemble the Layers
Spread half of the brownie batter evenly into the prepared pan. Arrange the Oreos in a single layer on top of the batter, covering as much surface as possible. Gently spread the remaining brownie batter over the Oreos and smooth the top.
4. Bake
Bake for 35–40 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Remove from the oven and allow the brownies to cool completely in the pan.
5. Decorate
Melt the white chocolate or candy melts in a microwave-safe bowl in 30-second intervals, stirring until smooth. Divide into bowls and tint with orange and purple coloring. Drizzle over the cooled brownies. While still wet, add Halloween sprinkles, candy eyeballs, and crushed Oreos if desired. Let set for 20–30 minutes.
6. Slice and Serve
Use the parchment overhang to lift the brownies out of the pan. Cut into 16 squares, wiping the knife between cuts for clean edges. Arrange on a platter and enjoy!
