Step‑by‑Step Instructions for Halloween Oreo Cookie Boo Brownies

Step 1: Prep the Pan
Begin by preheating your oven to 350°F (175°C). While it warms up, take a 9×9-inch baking pan and line it with parchment paper, allowing some paper to hang over the edges for easy removal later. This step ensures your Halloween Oreo Cookie Boo Brownies will come out cleanly and effortlessly.

Step 2: Mix Ingredients
In a large mixing bowl, melt butter until smooth and combine it with granulated sugar until the mixture is creamy and well-blended. Once combined, add in the eggs and vanilla extract, mixing thoroughly until incorporated. In a separate bowl, whisk together the all-purpose flour, salt, and crushed Oreo cookies. Gradually fold the dry mixture into the wet ingredients, followed by the chocolate chips, ensuring everything is evenly mixed.

Step 3: Assemble the Brownies
Pour the thick brownie batter into the prepared pan, spreading it evenly with a spatula for a smooth top. Next, take whole Oreo cookies and press them gently into the surface of the batter, ensuring the festive designs are facing up. This will create an eye-catching presentation and enhance the flavors of your Halloween Oreo Cookie Boo Brownies.

Step 4: Bake the Brownies
Place the pan in your preheated oven and bake for 30-32 minutes, keeping an eye on them during the last few minutes. To check if they’re done, insert a toothpick into the center of the brownies; it should come out with a few moist crumbs, indicating the perfect fudgy texture.

Step 5: Cool and Slice
Once baked to perfection, remove the brownies from the oven and let them cool in the pan for about 10-15 minutes. Using the overhanging parchment paper, carefully lift the brownies out of the pan. Allow them to cool completely on a wire rack before slicing them into squares, revealing the delicious layers of chocolatey goodness and crunchy Oreos.

Make Ahead Options

These Halloween Oreo Cookie Boo Brownies are perfect for meal prep enthusiasts! You can prepare the brownie batter up to 24 hours in advance by mixing the ingredients and storing the batter in an airtight container in the refrigerator. This helps enhance the flavors while ensuring it stays fresh. Additionally, you can crush the Oreo cookies and measure out the chocolate chips ahead of time, storing them separately for quick assembly. When you’re ready to bake, simply pour the chilled batter into your pan, press the whole Oreo cookies on top, and bake as directed. This way, you’ll have scrumptious brownies ready with minimal effort for your Halloween gatherings!
