Step‑by‑Step Instructions for Monster Mash Brownies
Step 1: Prepare Frosting
Begin by dividing your American buttercream frosting into several portions based on your desired colors for the Monster Mash Brownies. Using food gels, tint each frosting portion with vibrant colors, mixing thoroughly with a spatula until you achieve your preferred shades. This colorful foundation will bring your spooky creations to life later on!
Step 2: Preheat Oven
Preheat your oven to 175°C (340°F) while you prepare your baking tin. Take a 32cm x 24cm baking tin, generously grease it with butter, and line it with parchment paper, ensuring it overhangs slightly for easy removal later. This step is crucial to achieving those perfectly baked Monster Mash Brownies without sticking.
Step 3: Melt Butter & Chocolate
In a microwave-safe bowl, combine the unsalted butter and dark chocolate. Melt them together in 20-second intervals, stirring between each interval to achieve a smooth, glossy mixture. Be patient and watch closely; once fully melted, let it cool slightly to avoid cooking the eggs in the next step.
Step 4: Mix Batter
Whisk the granulated sugar into the melted chocolate mixture until combined, and then add the large eggs, blending until fully incorporated. Next, sift in the unsweetened cocoa powder and all-purpose flour, gently folding them in until just combined. Finally, stir in the white and dark chocolate chips for added flavor, creating a luscious brownie batter.
Step 5: Bake
Pour your thick brownie batter into the prepared baking tin, spreading it evenly with a spatula. Bake in the preheated oven for about 30 minutes. The Monster Mash Brownies are done when a toothpick inserted into the center comes out with moist crumbs; be careful not to overbake, as they should remain fudgy.
Step 6: Cool Brownies
Once baked, remove the brownies from the oven and let them cool in the tin for about 1 hour at room temperature. Afterward, transfer them carefully to the fridge and chill for an additional hour. This cooling period helps firm up the brownies, making them easier to cut without crumbling.
Step 7: Cut Brownies
After chilling, carefully lift the brownies out of the tin using the parchment overhang. Place them on a cutting board and use a 2½-inch cookie cutter to cut them into 12 delightful squares, perfect for decorating. This fun cutting method ensures each piece has the same adorable shape for your spooky designs.
Step 8: Decorate
Using piping bags, apply various creative shapes and features with your colored frosting on top of each brownie square, transforming them into whimsical monsters. Add liquorice pieces to enhance their quirky features, making your Monster Mash Brownies not only delicious but also visually captivating for Halloween festivities.
