Ingredients

For the Brownie Layer:

  • 1 cup (2 sticks) unsalted butter, melted

  • 2 cups granulated sugar

  • 1 cup packed brown sugar

  • 4 large eggs

  • 1 tablespoon vanilla extract

  • 1 cup unsweetened cocoa powder (Dutch-processed preferred)

  • 1 cup all-purpose flour

  • 1/2 teaspoon baking powder

  • 1/2 teaspoon salt

  • 1 cup semi-sweet chocolate chips (optional, for extra fudginess)

For the Oreo Layer:

  • 20–24 Halloween Oreos (with orange creme center) or classic Oreos

For the Festive Topping:

  • 1 1/2 cups white chocolate or candy melts

  • Orange and purple food coloring or candy melts

  • Candy eyeballs (optional but fun!)

  • Crushed Oreos for garnish (optional)

Step-by-Step Instructions

Step 1: Prepare the Baking Pan

  1. Preheat oven to 350°F (175°C).

  2. Line a 9×13-inch baking dish with parchment paper, leaving some overhang for easy lifting later.

  3. Lightly grease the parchment with butter or nonstick spray.

Step 2: Make the Brownie Batter

  1. In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth and glossy.

  2. Add in the eggs one at a time, whisking well after each addition. Stir in the vanilla extract.

  3. In another bowl, sift together cocoa powder, flour, baking powder, and salt.

  4. Gradually add the dry ingredients into the wet mixture. Stir until just combined—do not overmix.

  5. If using, fold in the chocolate chips for extra fudginess.

Step 3: Assemble the Layers

  1. Pour half of the brownie batter into the prepared baking pan and spread evenly.

  2. Arrange Oreos in a single layer over the batter. Try to fit as many as you can—this gives that perfect crunch in the middle.

  3. Spread the remaining brownie batter over the top, covering the Oreos completely. Smooth the surface with a spatula.

Step 4: Bake the Brownies

  1. Place in the oven and bake for 35–40 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter).

  2. Remove from the oven and allow to cool completely in the pan on a wire rack.

Step 5: Decorate for Halloween

  1. Melt the white chocolate or candy melts in a microwave-safe bowl in 30-second intervals, stirring in between, until smooth.

  2. Divide the melted chocolate into separate bowls and tint with orange and purple food coloring.

  3. Drizzle the colored chocolate over the cooled brownies in a spooky pattern.

  4. While the chocolate is still wet, sprinkle on Halloween sprinkles and add candy eyeballs for a creepy-cute look.

  5. Let the chocolate set for 20–30 minutes before slicing.

Step 6: Slice and Serve

  1. Use the parchment overhang to lift brownies from the pan.

  2. Cut into 16 squares with a sharp knife, wiping clean between cuts for neat edges.

  3. Serve on a festive Halloween tray and watch them disappear!

Tips for Success

  • Use Halloween Oreos – The orange creme adds festive color when sliced.

  • Don’t overbake – Slightly underbaking keeps brownies fudgy.

  • Cool before decorating – If brownies are warm, the chocolate drizzle will melt off.

  • Sharp knife trick – For clean cuts, dip the knife in hot water, dry, then slice.

  • Make-ahead friendly – Bake a day ahead and decorate the next day.

Variations

  • Spiderweb Brownies – Pipe white chocolate spiderwebs on top for a spooky effect.

  • Candy Bar Layer – Add chopped Snickers, Kit Kats, or Reese’s cups with the Oreos.

  • Pumpkin Spice Twist – Add 1 teaspoon pumpkin pie spice to the batter for fall flavor.

  • Frosted Brownies – Top with cream cheese frosting before adding sprinkles.

  • Monster Brownies – Use green candy melts and purple sprinkles for Frankenstein vibes.

Storage & Make-Ahead

  • Room Temperature: Store in an airtight container for up to 3 days.

  • Refrigerator: Keeps well for 5–6 days, though texture will firm up slightly.

  • Freezer: Wrap individual brownies in plastic wrap, then foil, and freeze up to 3 months. Thaw overnight before serving.
