Step-by-Step Instructions for Halloween Oreo Cookie Boo Brownies
Step 1: Prepare the Pan
Start by preheating your oven to 350°F (175°C). Meanwhile, line an 8x8-inch baking pan with parchment paper, allowing some overhang for easy removal of your Halloween Oreo Cookie Boo Brownies. This step ensures a hassle-free way to lift out the brownies once they are cool and ready to slice!
Step 2: Mix the Batter
In a large mixing bowl, prepare the brownie batter according to the Baker by Nature’s Oreo Brownies recipe. Fold in roughly chopped Halloween Boo Oreos and chocolate chips, stirring until just combined. The batter should be thick and luscious, filled with tiny bits of cookies and chocolate, promising an indulgent treat that everyone will love.
Step 3: Pour and Decorate
Pour the decadent brownie batter into the prepared pan, spreading it evenly with a spatula. Before baking, arrange whole Halloween Boo Oreos on the surface, gently pressing them into the batter. This will create a delightful topping that enhances the texture and presentation of your Halloween Oreo Cookie Boo Brownies!
Step 4: Bake the Brownies
Place the pan in the preheated oven and bake for approximately 28-32 minutes. Keep an eye on them, checking for a slightly fudgy texture by inserting a toothpick in the center; it should come out with a few moist crumbs. Avoid overbaking for that perfect gooeyness that will delight your family and friends.
Step 5: Cool and Slice
Once baked, remove your brownies from the oven and allow them to cool in the pan for about 15 minutes. After cooling, carefully lift the brownies out using the parchment paper. Transfer them to a cutting board and slice them into squares. These Halloween Oreo Cookie Boo Brownies are now ready to be enjoyed, perfect for creating sweet memories!
