Step‑by‑Step Instructions for Halloween Oreo Cookie Boo Brownies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it warms up, grab a 9x13-inch baking pan and line it with parchment paper, allowing some excess to hang over the edges. This will make removing your brownies easier later. Set the pan aside and get ready to whip up the brownie batter for your Halloween Oreo Cookie Boo Brownies.
Step 2: Mix the Brownie Batter
Next, prepare the brownie batter using the Oreo Brownies recipe from Baker by Nature. In a large mixing bowl, combine your ingredients and mix until you achieve a smooth and creamy consistency. The goal is to have a luscious base that will hold all that deliciousness, so don't rush this step. Once mixed, set the bowl aside to move on to the next tasty part.
Step 3: Fold in the Crunch
Take the brownie batter and gently fold in your crushed Halloween Boo Oreos along with a cup of semi-sweet chocolate chips. Use a spatula to ensure even distribution, as mixing too aggressively can deflate the batter. This step adds delightful bits of cookie and extra chocolatey goodness to your brownies, making them irresistible treats to bite into!
Step 4: Pour and Smooth
Now, pour the brownie batter into your prepared pan, spreading it evenly using a spatula or the back of a spoon. Smooth the top so each brownie bakes uniformly. With the enticing aroma of the Halloween Oreo Cookie Boo Brownies filling your kitchen, it's time to add a festive touch on top before baking.
Step 5: Decorate with Oreos
Before sending your brownies into the oven, take some whole Halloween Boo Oreos and gently press them into the top of the batter, ensuring they face up for a striking presentation. This not only enhances the look but also adds a crunchy layer of fun to each bite. Now, your batter is ready for the oven!
Step 6: Bake to Perfection
Slide the pan into your preheated oven and bake for about 32 minutes. Keep an eye on them as they bake, ensuring not to overbake for the fudgy texture we desire. As the brownies rise and get puffy, a delightful aroma will fill the air, signaling their almost-ready state for removal from the oven.
Step 7: Check for Doneness
To test your brownies, insert a toothpick into the center, being cautious not to hit a chocolate chip, as they could give a false indication of doneness. You want a few moist crumbs to cling to the toothpick when they’re ready. If it comes out clean, it's time to take your Halloween Oreo Cookie Boo Brownies out!
Step 8: Cool and Cut
Once baked, let your brownies cool completely in the pan on a wire rack. Patience is key here, as allowing them to set will make cutting into those delicious squares much easier. Once cooled, use the parchment paper overhang to lift your brownies from the pan, slice them into squares, and get ready to impress your family and friends with your festive creation!
How to Store and Freeze Halloween Oreo Cookie Boo Brownies
Room Temperature: Store brownies in an airtight container at room temperature for up to 3 days. This keeps them fresh and chewy, perfect for snacking!
Fridge: If you prefer a firmer texture, you can refrigerate the brownies for up to a week. Make sure they're in an airtight container to avoid absorbing any odors.
Freezer: To freeze, wrap brownies tightly in plastic wrap and then place them in a freezer-safe bag. They can be frozen for up to 3 months. Thaw at room temperature before enjoying.
Reheating: For a warm treat, reheat individual squares in the microwave for about 10-15 seconds. Enjoy the gooeyness of your Halloween Oreo Cookie Boo Brownies like they just came out of the oven!
