Ingredients You’ll Need

Here’s what you’ll need to whip up these festive Oreo brownies:

  • 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
  • 15 Halloween Oreos (plus 5 extra for topping)

Butter and oil together create a soft, moist crumb while cocoa powder brings that deep, chocolatey flavor. The Halloween Oreos don’t just add crunch—they bring a fun pop of orange color and a hint of vanilla creaminess that makes these brownies extra special.

Step-by-Step Instructions for Oreo Brownies

Prep the oven and pan

Preheat your oven to 350°F and line an 8×8-inch baking pan with parchment paper. This helps with easy removal later and keeps your edges neat.

Melt butter, oils, and sugars

In a microwave-safe bowl, melt butter, vegetable oil, granulated sugar, and brown sugar in 30-second intervals. Stir between each until smooth. Then microwave for one final minute and whisk well to dissolve the sugar. This step gives your brownies that shiny, crackly top everyone loves.

Whisk in eggs and vanilla

Whisk in the eggs one at a time, making sure each is fully blended before adding the next. Add vanilla extract and stir again. This makes your batter rich and velvety.

Add dry ingredients

Sift in cocoa powder, salt, and flour. Fold gently until just combined—don’t overmix or you’ll lose that fudgy texture.

Layer the batter with Oreos

Pour half the batter into your prepared pan. Arrange 15 Halloween Oreos across the layer, pressing lightly so they sink a bit. Then, spread the remaining batter over the top and smooth it out. Crush 5 more Oreos and sprinkle them generously over the surface.

Bake and cool completely

Bake for 30 minutes, or until a toothpick inserted comes out with a few moist crumbs. Cool completely before slicing—this might take several hours, but it’s worth it. Waiting ensures perfect, clean edges and a gooey center.

Tips for the Best Halloween Brownies

Patience pays off—let your brownies cool for several hours (even overnight) for neat cuts and the perfect fudgy bite. Use a sharp knife dipped in warm water and wiped clean between slices. If you want to boost the richness, fold in 1/3 cup chocolate chips before baking. You can also top your brownies with vanilla or orange frosting for a fun Halloween look. For extra flair, drizzle melted chocolate or add candy eyeballs. These brownies are flexible too, so you can make them ahead for parties or wrap them up for trick-or-treat gifts.

Storage and Freezing Guide

How to store Oreo brownies at room temperature

Keep your brownies in an airtight container at room temperature for up to 5 days. They’ll stay moist and chewy if stored in a cool, dry spot.

Can you refrigerate Oreo brownies?

Yes, you can! Refrigeration helps them last longer—up to a week. Just make sure to seal them tightly to prevent drying.

Freezing instructions and thawing tips

Freeze cooled brownies in a container or wrap them individually. They’ll keep for up to 3 months. To serve, thaw overnight in the fridge or for a few hours at room temperature. For that fresh-from-the-oven feel, microwave for 10 seconds before serving.

Variations and Substitutions

You can easily swap Halloween Oreos for any seasonal flavor—peppermint for Christmas, red velvet for Valentine’s Day, or golden Oreos for summer. Add mix-ins like peanut butter chips or chunks of white chocolate for a twist. If you love frosting, spread a layer of ganache or buttercream once they’ve cooled. These brownies also look amazing next to Mummy Brownies or Spooky Eyeball Fudge Brownies at your Halloween dessert table!
