Ingredients for Halloween Oreo Brownies

• Eggs: Bind the batter and add structure while keeping it moist.
• Vanilla Extract: Boosts flavor with a warm, aromatic touch.
• Flour: Provides structure without overpowering the fudginess.
• Halloween Oreos: The star ingredient—bright orange filling for a festive pop inside and on top of the brownies.
• Salt: Enhances overall flavor and balances sweetness.
Ingredient Swaps & Alternatives
• Gluten-Free: Use a 1:1 gluten-free baking flour blend instead of all-purpose.
• Extra Chocolate: Mix in chocolate chips or chunks for an even richer bite.
• Different Oreos: Try peppermint Oreos for Christmas, golden Oreos for spring, or birthday cake Oreos for celebrations.
• Dairy-Free: Swap butter for vegan butter and check that your Oreos are dairy-free.
How to Make Halloween Oreo Brownies
- Prepare the Pan: Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper for easy removal.
- Melt & Mix: In a microwave-safe bowl, melt butter, oil, and both sugars together. Stir until smooth and glossy.
- Add Wet Ingredients: Whisk in eggs one at a time, followed by vanilla extract. Mix until the batter pulls slightly from the bowl.
- Incorporate Dry Ingredients: Gently fold in flour, cocoa powder, and salt until just combined. Do not overmix.
- Layer the Batter: Spread half the brownie batter into the prepared pan. Arrange whole and halved Halloween Oreos on top. Cover with the remaining batter.
- Top It Off: Sprinkle crushed Oreos over the surface for extra crunch and decoration.
- Bake: Place in the oven for about 30 minutes, or until the center is just set.
- Cool & Slice: Allow brownies to cool completely on a wire rack before slicing for clean, fudgy squares.

Tips for the Best Halloween Oreo Brownies
• Let brownies cool for several hours before slicing to avoid a gooey mess.
• For extra neat cuts, dip your knife in hot water and wipe clean between slices.
• If you don’t own a microwave, use a double boiler to melt butter, sugar, and oil.
• For a decadent upgrade, top cooled brownies with orange frosting, ganache, or chocolate buttercream.
Storage & Freezing Instructions
• Room Temperature: Store in an airtight container for up to 5 days.
• Refrigerator: Keep chilled for up to 1 week. Bring to room temperature before serving.
• Freezer: Wrap brownies tightly and freeze for up to 3 months. Thaw overnight in the fridge or reheat briefly in the microwave for a gooey texture.
Fun Variations & Pairings
• Spooky Upgrade: Drizzle melted white chocolate tinted with food coloring for a spiderweb effect.
• Party Platter: Serve alongside candy corn, pumpkin cookies, or monster cupcakes for a Halloween dessert board.
• Ice Cream Pairing: Warm a brownie square and top with vanilla ice cream for a molten-lava cake style dessert.
• Holiday Adaptation: Swap in red velvet Oreos for Valentine’s Day or green-filled Oreos for St. Patrick’s Day.

Frequently Asked Questions
Can I make Halloween Oreo Brownies ahead of time?
Yes! You can bake them up to two days in advance and store them in an airtight container. For ultimate freshness, wait to slice them until just before serving.
How do I know when Halloween Oreo Brownies are done baking?
Check for doneness around 30 minutes by inserting a toothpick into the center. It should come out with a few moist crumbs but not wet batter. Overbaking can dry out the fudgy texture.
Can I make these brownies without Halloween Oreos?
Absolutely! Regular Oreos or any seasonal variety will work. The classic brownie base pairs well with all Oreo flavors, from peppermint to birthday cake.
How do I get clean brownie slices?
Allow the brownies to cool completely—ideally for several hours. Use a sharp knife dipped in hot water and wiped clean between cuts for perfect squares
