Kitchen Equipment You’ll Need

Before you begin, gather the following tools:

  • Large mixing bowl
  • Medium mixing bowl
  • Whisk or electric hand mixer
  • Rubber spatula
  • 9×13-inch baking dish
  • Parchment paper
  • Cooling rack
  • Measuring cups and spoons

Having everything ready makes baking smooth and fun.

Step-by-Step Preparation for Spooky Oreo Brownies

  1. Preheat the oven to 350°F (175°C). Line your 9×13-inch pan with parchment paper and lightly spray with nonstick spray.
  2. Melt the butter and whisk in the sugar until the mixture is smooth and glossy.
  3. Add the eggs and vanilla, beating in the eggs one at a time. Stir in vanilla extract until combined.
  4. Mix dry ingredients: In a separate bowl, sift together the flour, cocoa powder, and salt.
  5. Combine wet and dry: Slowly fold the dry ingredients into the wet mixture until just combined.
  6. Stir in chocolate chips, being careful not to overmix.
  7. Layer in the pan: Pour half the batter into the pan. Lay a single layer of Halloween Oreos on top. Then add the rest of the batter, spreading to cover the cookies.
  8. Decorate: Press a few extra Oreos into the top and scatter festive sprinkles over the surface.
  9. Bake for 35–40 minutes or until a toothpick comes out with moist crumbs. Let cool before slicing.

These brownies make a great addition to a Halloween dessert spread alongside treats like Halloween Doughnuts or Monster Eyeball Pizza.

Tips to Nail Your Halloween Brownies Spooky Look
