Better-Than-Grandma Tips
Hot melted butter is essential! This is the secret to achieving those perfectly crackled brownie tops we all adore. Make sure your butter isn’t just melted, but hot when you add it to the mix.
Don’t overmix the batter! Gently fold the dry ingredients into the wet ingredients until just combined. Overmixing will incorporate too much air, resulting in cakey brownies instead of fudgy ones. Check out our tips for fudgy brownies for more ideas.
Watch the baking time closely. Start checking for doneness around the 20-minute mark. The brownies should be set around the edges, but the center might still appear slightly soft. A toothpick inserted into the center should come out with moist crumbs attached – that’s your cue for perfect fudginess!
Ingredients
- 1 cup (2 sticks) unsalted butter, melted
- ½ cup vegetable oil
- 2 cups granulated sugar
- 4 large eggs
- 2 teaspoons vanilla extract
- 1 ½ cups all-purpose flour
- ¾ cup unsweetened cocoa powder
- 1 teaspoon salt
- 1 (11-ounce) package Halloween Oreos, roughly chopped
Instructions
- Preheat your oven to 350°F (175°C). Lightly grease an 8-inch square baking pan and line it with parchment paper, leaving some overhang on the sides to make lifting the brownies out easier later.
- In a medium bowl, whisk together the hot melted butter, oil, and sugar for about a minute until well combined.
- Add the eggs and vanilla extract to the butter-sugar mixture and beat until the mixture lightens in color, about another minute.
- In a separate bowl, whisk together the flour, cocoa powder, and salt. Gently fold the dry ingredients into the wet ingredients until just combined. Be careful not to overmix!
- Fold in the chopped Halloween Oreos, distributing them evenly throughout the batter.
- Pour the batter into the prepared pan and spread evenly. Bake for 20-25 minutes, or until the edges are set and a toothpick inserted into the center comes out with moist crumbs. Don’t overbake!
- Let the brownies cool completely in the pan before slicing and serving. This will allow them to firm up and prevent them from crumbling. Enjoy!

Flavor Twists
Want to put your own spin on these Halloween Oreo Brownies? Here are a few ideas:
- Nutty Delight: Add 1/2 cup of chopped walnuts, pecans, or your favorite nuts to the batter along with the Oreos.
- Peanut Butter Swirl: Swirl a few tablespoons of peanut butter into the batter before baking for a peanut butter-chocolate explosion.
- Minty Freshness: Use mint Oreos instead of Halloween Oreos for a refreshing twist. You might enjoy this tasty mint chocolate recipe.
- Extra Chocolate Chunk: Add in some semi-sweet or dark chocolate chunks. The melted chocolate inside will ooze out when you bite into them!
Get creative and make them your own!
How do I store these Halloween Oreo Brownies?
You can store these brownies in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. For longer storage, freeze them for up to 3 months.
Can I make these brownies without the Oreos?
Absolutely! While the Oreo pieces add a delightful Halloween touch, feel free to leave them out if you prefer a classic brownie. Or try swapping the Oreos for your favorite mix-ins, like chocolate chips or chopped nuts!
When is the best time to eat these brownies?
These brownies are best enjoyed slightly warm, straight from the oven. However, they are still delicious at room temperature, and the Oreos give them an extra delightful crunch once they’ve cooled completely.
Can I double the recipe to feed a crowd?
Yes, you can double this recipe to make a larger batch. Just make sure you use a larger baking pan (9×13 inches) and adjust the baking time accordingly.
Keep an eye on them and test for doneness using a toothpick – it should come out with moist crumbs, not completely clean, for the perfect fudgy texture.
How to Serve

These Halloween Oreo Brownies are delicious on their own, but why stop there? Here are a few ideas for serving them up in style:
- Warm with a scoop of vanilla ice cream: The ultimate comfort food combination.
- Drizzled with melted chocolate: Because you can never have too much chocolate!
- Topped with whipped cream and Halloween sprinkles: Add a touch of spooky fun.
- Alongside a glass of cold milk: A classic pairing that never fails. See our milk and cookie recipes for a sweet idea!
No matter how you serve them, these brownies are sure to be a hit!
