Ingredients
Scale
Brownie Batter
- 2/3 cup butter
- 1/4 cup vegetable oil
- 1 cup granulated sugar
- 1/3 cup brown sugar
- 2/3 cup unsweetened cocoa powder
- 2 eggs, cold
- 1 tsp vanilla extract
- 1/2 tsp salt
- 1/2 cup all-purpose flour
- 15 Oreo cookies (10–12 chopped for batter, 3–5 whole for topping)
Optional Frosting and Decorations
- 1 cup unsalted butter, softened
- 4 cups sifted powdered sugar
- 1/2 tsp vanilla extract
- 1/4 cup heavy cream
- Pinch of salt
- Gel food coloring (orange, black, green)
- Candy eyes
- Sprinkles
- Candy corn or other festive Halloween decorations
Instructions
- Prepare Pan and Oven: Preheat oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang for easy lifting of the brownies after baking.
- Combine Wet Ingredients: In a large bowl, melt 2/3 cup butter. Stir in 1/4 cup vegetable oil, 1 cup granulated sugar, and 1/3 cup brown sugar until well combined. Whisk in 2 cold eggs one at a time until fully incorporated. Stir in 1 tsp vanilla extract to flavor the mixture.
- Combine Dry Ingredients: In a separate medium bowl, whisk together 2/3 cup unsweetened cocoa powder, 1/2 cup all-purpose flour, and 1/2 tsp salt, ensuring even distribution for the batter.
- Mix Batter and Fold in Oreos: Gradually add the dry ingredient mixture to the wet ingredient mixture. Mix gently until just combined, careful not to overmix to keep brownies tender. Fold in 10-12 roughly chopped Oreo cookies for texture and flavor distribution.
- Bake Brownies: Pour the batter evenly into the prepared baking pan. Bake in preheated oven for 25-30 minutes or until a toothpick inserted into the center comes out with moist crumbs but no wet batter, indicating perfect fudginess.
- Cool Brownies: Remove brownies from oven and let cool completely in the pan on a wire rack for at least 1.5 hours. Once cooled, use the parchment paper overhang to lift the brownies out of the pan easily.
- Prepare Frosting (Optional): To make festive frosting, beat 1 cup softened unsalted butter until light and fluffy. Gradually add 4 cups sifted powdered sugar, 1/2 tsp vanilla extract, 1/4 cup heavy cream, and a pinch of salt; beat until smooth and spreadable. Divide and tint portions with gel food coloring to create Halloween-themed colors like orange, black, and green.
- Decorate Oreos (Optional): Take the remaining 3-5 whole Oreo cookies and decorate them into fun Halloween characters such as mummies, spiderwebs, or monsters using the colored frosting, candy eyes, and sprinkles. Let them set slightly to firm up.
- Assemble and Final Decorations: Spread a base layer of the colored frosting evenly over the cooled brownies. Arrange the decorated Halloween Oreo cookies on top and embellish with additional Halloween sprinkles, candy corn, or other themed toppings for visual appeal and extra flavor.
- Serve: Cut the brownies into squares with a sharp knife, wiping the knife clean between cuts for neat slices. Serve your festive Halloween Oreo Brownies fresh. Store leftovers in an airtight container at room temperature for 3-4 days or refrigerate up to one week.
Notes
- For fudgier brownies, avoid overmixing the batter after adding the dry ingredients.
- Use cold eggs to help the batter hold together better during mixing.
- The frosting and decorated Oreos are optional but add a festive touch perfect for Halloween parties.
- Ensure brownies cool completely before frosting to avoid melting the frosting layer.
- Store brownies airtight to maintain freshness and moisture.
