How to Make Spooky Oreo Boo Brownies

Prep the Pan: Line a 9×9 inch baking pan with parchment paper, ensuring it overhangs on the sides for easy removal later. This will give you beautifully sliced brownies!
Melt Butter: In a medium saucepan, melt butter over low heat until fully liquid. Remove from heat and let it cool slightly to prevent cooking the eggs later.
Mix Ingredients: In a large mixing bowl, combine the melted butter, brown sugar, eggs, and vanilla extract. Stir until smooth, before gently adding the flour and baking powder, mixing until just combined.
Fold in Ingredients: Carefully fold in the crushed Halloween Oreos and chocolate chips, making sure not to over mix to keep the batter nice and fudgy.
Bake: Pour the brownie batter into the prepared pan, spreading it evenly. Scatter whole Oreo pieces on top and bake at 350°F (175°C) for approximately 32 minutes, or until a toothpick inserted comes out with moist crumbs.
Cool & Slice: Once baked, allow the brownies to cool in the pan for 10-15 minutes. Lift them out using the parchment paper, then slice into squares and serve!

Optional: Top with a dusting of powdered sugar for a ghostly finish.

Parchment Paper: Using parchment paper in your baking pan not only makes for easy removal but also ensures clean cuts when slicing your brownies.
Mixing Technique: Always mix until just combined after adding the flour to keep your Spooky Oreo Boo Brownies tender and fudgy. Overmixing leads to dense brownies!

Customizing Flavors: Feel free to experiment with add-ins! Peanut butter chips or seasonal sprinkles can enhance the festive appeal of your Spooky Oreo Boo Brownies.
Cooling Properly: Let the brownies cool for at least 10-15 minutes in the pan before lifting them out. This will help them set and slice beautifully.

Spooky Oreo Boo Brownies Recipe FAQs

How do I select the best Oreo cookies for these brownies?
Absolutely! For the best festive touch, opt for Halloween-themed Oreo cookies. They’re not only visually appealing but also add that extra crunch and flavor that complements the rich chocolate of your brownies. If you can’t find Halloween Oreos, regular ones can work just as well—just crush them into chunky pieces for added texture!

How should I store leftover Spooky Oreo Boo Brownies?
Keep your delicious brownies in an airtight container at room temperature for up to 5 days. If you want to keep them fresh for a longer period, refrigerate them, where they can last for up to a week. For maximum freshness, I recommend bringing them back to room temperature before serving for that fudgy, soft texture!

Can I freeze Spooky Oreo Boo Brownies?
Yes, you can! Wrap the cooled brownies tightly in plastic wrap and place them in a freezer-safe container. They can be frozen for up to 3 months. When you’re ready to enjoy them, simply thaw in the refrigerator overnight. To enhance the experience, warm them in the microwave for 10-15 seconds before serving!

What if my brownies turn out too dense or dry?
If your brownies come out dense, it may be due to overmixing after adding the flour. Remember, mix just until combined to keep that fudgy texture. If they turn out dry, you might have baked them too long. Make sure to check for doneness with a toothpick; it should come out with moist crumbs, not completely clean. Keep an eye on the baking time to prevent overbaking.

Are there any dietary considerations for pets or allergies?
It’s best to avoid giving Spooky Oreo Boo Brownies to pets, particularly dogs, as chocolate can be toxic to them. For those with allergies, consider swapping out ingredients: you can use dairy-free chocolate chips and gluten-free flour if needed. Always check the ingredient labels for allergens to ensure a safe treat for everyone!
