Halloween Oreo Brownies Recipe

Introduction

Celebrate Halloween with these festive Oreo brownies that combine rich chocolate, crunchy cookies, and spooky green frosting. Perfect for parties or a fun treat, they’re as delicious as they are eye-catching.

Ingredients

• 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
• 1 cup unsalted butter, softened (for frosting)
• 4 cups powdered sugar, sifted (for frosting)
• 1/2 tsp pure vanilla extract (for frosting)
• 3-4 tbsp milk or heavy cream (for frosting)
• Green gel food coloring (for frosting)
• Pinch of salt (for frosting)
• 5 Halloween-themed Oreo cookies (for topping)
• Edible candy eyes (for decoration)
• Assorted Halloween sprinkles (optional)
• Melting chocolate (white or dark, optional, for decoration)

Instructions

1. Step 1: Preheat the oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang for easy removal, and grease lightly.
2. Step 2: Melt 2/3 cup butter and let it cool slightly. In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth. Beat in the cold eggs one at a time, then add 1 teaspoon vanilla extract.
3. Step 3: In a separate bowl, whisk together the sifted cocoa powder, all-purpose flour, and salt.
4. Step 4: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Gently fold in the coarsely crushed Oreo cookies.
5. Step 5: Pour the batter evenly into the prepared pan. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with moist crumbs. Avoid overbaking. Let the brownies cool completely on a wire rack for 1-2 hours.
6. Step 6: For the frosting, beat the softened butter until light and fluffy. Gradually add powdered sugar, vanilla extract, a pinch of salt, and milk. Beat until smooth and spreadable, then mix in green gel food coloring to your desired spooky shade.
7. Step 7: Once the brownies are fully cooled, spread the green frosting evenly over the top. Arrange the 5 Halloween-themed Oreo cookies on the frosting. Decorate with edible candy eyes, sprinkles, and optional melted chocolate drizzles or spiderweb designs.
8. Step 8: Chill the decorated brownies in the refrigerator for at least 30 minutes to set the frosting for clean slicing. Use a hot, clean knife to slice and serve.

Tips & Variations

• Use cold eggs to help the batter set properly and create fudgy brownies.
• For an extra crunch, stir in chopped nuts along with the crushed Oreos.
• If you prefer, substitute the green gel food coloring with orange or purple for a different Halloween vibe.
• To make cutting easier, warm the knife under hot water and wipe it dry before slicing.
• Try drizzling melted white chocolate to create spiderweb designs for festive decoration.

Storage

Store brownies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week. Before serving, bring refrigerated brownies to room temperature for the best texture. Leftover brownies can be reheated briefly in the microwave to soften the frosting.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

Can I use regular Oreos instead of Halloween-themed ones?

Yes, regular Oreos work perfectly for the crushed cookies inside and for decorating. Halloween-themed Oreos add a seasonal touch but are not necessary for the flavor.

Can I make these brownies gluten-free?

To make gluten-free brownies, substitute the all-purpose flour with a gluten-free baking flour blend, ensuring it contains xanthan gum or another binder. The texture may vary slightly but should still be delicious.

Ingredients

Scale 1x2x3x

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.
