How to Make Halloween Brookies
Follow these simple steps to prepare this delicious Halloween Brookies:
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Take an 8×8 square baking dish, then grease it lightly and line it with parchment paper for easy removal of the brookies later on.
Step 2: Melt the Chocolate and Butter
In a heatproof measuring glass, combine the unsalted butter and chopped bittersweet chocolate. Microwave in 30-second intervals, stirring in between until smooth. Make sure it’s completely melted and well-combined.
Step 3: Mix the Brownie Batter
In a large bowl, use a hand or stand mixer with the whisk attachment to mix together the light brown sugar, granulated sugar, and egg at high speed until pale and super smooth, about 3 minutes. Gradually drizzle in the melted chocolate while mixing, then add the vanilla extract.
Step 4: Combine Dry Ingredients
Pour in the flour, cornstarch, Dutch-process cocoa, and salt. Use a rubber spatula to mix everything together, then fold in the mini chocolate chips. Set this delicious brownie batter aside.
Step 5: Whip Up the Cookie Dough
In another medium bowl, combine the flour, oats, baking powder, and salt for the cookie dough. In a separate large bowl, beat together the creamy peanut butter, softened butter, light brown sugar, and granulated sugar until smooth. Add the vanilla extract and egg, mixing on medium-high speed for about 2 minutes.
Step 6: Finish the Cookie Dough
Stir in the dry ingredients for the cookie dough using a rubber spatula, followed by the mini chocolate chips and Reese’s Pieces until well combined.
Step 7: Assemble the Brookies
In your prepared baking pan, alternate spoonfuls of the brownie batter and cookie dough. Use a spatula to spread everything evenly. Top with a sprinkling of chocolate chips and any leftover Reese’s Pieces to make them extra festive!
Step 8: Bake and Decorate
Bake in your preheated oven for 30-35 minutes. When they come out, immediately press the candy eyes into the melted chocolate chips on top for a fun Halloween effect.
Allow the brookies to cool for 45 minutes to 1 hour, then lift them out using the parchment paper, cut into squares, and get ready to enjoy the spookiest treat of the season!
