Step-by-Step Guide to Making Spider Web Brownies

Step 1 – Preheat and prepare your pan
Preheat the oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper for easy removal.

Step 2 – Make the brownie batter
Whisk melted butter and sugar until combined. Add eggs one at a time, then vanilla. In a separate bowl, sift together flour, cocoa powder, salt, and baking powder. Fold the dry ingredients into the wet mixture until just combined.

Step 3 – Bake the brownies
Spread batter evenly in the prepared pan and bake for 25–30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Let cool completely before decorating.

Step 4 – Make the spider web design
Melt white chocolate or prepare your icing. Transfer to a piping bag or a zip-top bag with a tiny corner snipped off. Pipe three concentric circles on top of the brownies, then use a toothpick to drag lines outward from the center, creating a web.

Step 5 – Serve and enjoy
Cut into squares and garnish with candy eyes or Halloween sprinkles if desired.

Tips for Perfect Homemade Spider Web Brownies

• For fudgy brownies: Slightly underbake them — they’ll continue to set as they cool.
• For clean cuts: Chill the brownies before slicing.
• For a sharp web design: Use a steady hand and keep the icing at a medium thickness so it flows without spreading too much.
