4.6 from 136 reviews

Delicious Halloween Oreo Brownies featuring layers of rich brownie batter and crunchy Oreos, baked to chocolatey perfection. These festive treats combine classic brownie flavor with the iconic Oreo cookie for a fun and spooky dessert perfect for Halloween celebrations.

Ingredients

Scale

Brownie Batter

  • 1 box brownie mix (approximately 18.3 oz)
  • Ingredients called for on brownie mix box (usually eggs, oil, and water)

Cookies

  • 18 Oreo cookies, whole or broken into halves

Instructions

  1. Prepare Brownie Batter: Follow the instructions on the brownie mix box to prepare the batter, combining the mix with the required eggs, oil, and water until smooth and well blended.
  2. Layer Batter and Oreos: Pour a layer of brownie batter into a greased 9×13-inch baking pan. Arrange Oreo cookies evenly over the batter layer, either whole or broken in halves depending on preference. Pour the remaining brownie batter over the Oreos, spreading gently to cover them completely.
  3. Bake: Preheat your oven to 350°F (175°C). Bake the layered brownie batter and Oreos for 30–35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs but no wet batter.
  4. Cool: Remove the brownies from the oven and allow them to cool completely in the pan on a wire rack. This helps the brownies set and makes slicing easier.
  5. Serve: Slice into squares and serve as a festive Halloween treat, perfect for parties and gatherings.

Notes

  • You can use any flavor of Oreos for variety, such as mint or golden Oreos.
  • Ensure brownies are cool before slicing to maintain clean edges and prevent crumbling.
  • For an extra spooky touch, consider decorating with Halloween-themed sprinkles or edible markers.
  • If you prefer fudgier brownies, slightly underbake by reducing the time by 3-5 minutes but keep an eye to avoid raw batter.
