Ingredients

Scale

Brownie Batter

  • 2/3 cup unsalted butter, melted
  • 1/4 cup vegetable oil
  • 1 cup granulated sugar
  • 1/3 cup brown sugar
  • 2 large eggs, cold
  • 1 tsp pure vanilla extract
  • 2/3 cup unsweetened cocoa powder, sifted
  • 1/2 cup all-purpose flour, spooned and leveled
  • 1/2 tsp salt
  • 15 Oreo cookies, coarsely crushed

Green Buttercream Frosting

  • 1 cup unsalted butter, softened
  • 4 cups powdered sugar, sifted
  • 1/2 tsp pure vanilla extract
  • 3–4 tbsp milk or heavy cream
  • Green gel food coloring
  • Pinch of salt

Decoration

  • 5 Halloween-themed Oreo cookies
  • Edible candy eyes
  • Assorted Halloween sprinkles (optional)
  • Melting chocolate (white or dark, optional)

Instructions

  1. Prepare Pan & Oven: Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal, and lightly grease the parchment to prevent sticking.
  2. Combine Wet Ingredients: Melt 2/3 cup of unsalted butter and allow it to cool slightly. In a large mixing bowl, whisk together the melted butter with 1 cup granulated sugar and 1/3 cup brown sugar until the mixture is smooth and well combined. Beat in the 2 cold eggs one at a time to maintain emulsion, then stir in 1 teaspoon of pure vanilla extract for flavor.
  3. Mix Dry Ingredients: In a separate bowl, sift together 2/3 cup unsweetened cocoa powder, 1/2 cup all-purpose flour, and 1/2 teaspoon salt. Whisk well to evenly distribute all dry ingredients.
  4. Combine & Add Oreos: Gradually add the dry ingredient mixture into the wet ingredients, folding gently until just combined to avoid overmixing which can toughen the brownies. Carefully fold in 15 coarsely crushed Oreo cookies to incorporate that signature crunch and flavor.
  5. Bake Brownies: Pour the batter evenly into the prepared baking pan and smooth the top. Bake in the preheated oven for 25 to 30 minutes, or until a toothpick inserted in the center comes out with moist crumbs but not wet batter, indicating a fudgy texture. Avoid overbaking. Allow the brownies to cool completely on a wire rack for 1 to 2 hours before frosting.
  6. Prepare Green Frosting: In a mixing bowl, beat 1 cup of softened unsalted butter until light and fluffy. Gradually add 4 cups of sifted powdered sugar, 1/2 teaspoon pure vanilla extract, a pinch of salt, and 3 to 4 tablespoons of milk or heavy cream. Beat until the frosting is smooth, creamy, and spreadable. Add green gel food coloring dropwise, mixing until you achieve a vibrant spooky green hue perfect for Halloween.
  7. Assemble & Decorate: Once the brownies are completely cooled, spread the green buttercream frosting evenly over the top. Arrange the remaining 5 Halloween-themed Oreo cookies decoratively on the frosted surface. Garnish with edible candy eyes and, if desired, sprinkle Halloween-themed sprinkles or drizzle melted white or dark chocolate artistically to create spooky spiderwebs or other festive designs.
  8. Chill, Slice & Serve: Place the decorated brownies in the refrigerator to chill for at least 30 minutes; this helps the frosting set and allows for clean slicing. Use a hot, clean knife to slice the brownies into squares. Serve immediately or store in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week to maintain freshness.

Notes

  • Do not overmix the brownie batter; this keeps the texture fudgy and tender.
  • Ensure brownies are completely cool before frosting to prevent melting the buttercream.
  • Use a hot knife to slice brownies cleanly after chilling the decorated pan.
  • Optional melted chocolate can be used to add extra decorative touches like spiderwebs or drizzle patterns.
  • Store brownies in an airtight container to maintain freshness and texture.
