  • 4 large eggs
  • 1 teaspoon vanilla extract

  3. Whisk in eggs one at a time, then add vanilla extract.

  2. Bake for 30–35 minutes, or until a toothpick inserted comes out with moist crumbs.
  3. Allow brownies to cool completely before decorating.

Step 3: Make the Spider Web Decoration

  1. Melt white chocolate chips in the microwave in 20-second intervals, stirring between each, until smooth. (Or prepare white icing.)
  2. Transfer melted chocolate into a piping bag or a zip-lock bag with a small corner snipped off.
  3. Pipe 3–4 concentric circles onto the brownie surface.
  4. Using a toothpick, gently drag lines from the center of the circles outward, creating a spider web design.
  5. Add candy spiders or pipe small black icing spiders for extra spookiness.

  • Cut brownies into neat squares or rectangles.
  • Arrange on a dark platter for a spooky vibe.
  • Pair with a glass of milk, hot cocoa, or spiced cider.
  • Perfect for Halloween dessert tables or trick-or-treat gatherings.

  • Chill brownies before slicing for cleaner edges.
  • Use a squeeze bottle instead of piping bags for easier web design.
  • Add candy eyes to your spiders for extra fun.

Variations
