Halloween Spider Cake

Kids go absolutely wild for this Halloween spider cake. Two round cake layers get sculpted into a spider body, with a smaller circle cut from one layer forming the head. The clever part? That hole left behind gets filled with wobbly green gelatin, so when you slice into the body, there’s a bright, creepy surprise waiting inside.

The black frosting is simpler than it sounds. Start with store-bought chocolate frosting and stir in blue food coloring until it turns truly black. Chocolate is already dark, so the blue pushes it all the way there without needing specialty black food coloring.

Black licorice ropes bent into legs and big green gumballs for eyes complete the look. It’s the kind of project that’s more assembly than baking skill, which makes it a great one to tackle with kids.

Pro Tips

• Chill both cake layers before cutting and assembling. Cold cake is firmer and won’t crumble when you cut the head circle or trim the body shape.
• Use a drinking glass or round cookie cutter to get a clean circle for the spider’s head.
• Add the blue food coloring a few drops at a time to the chocolate frosting. It’s easier to go darker than to fix an overly blue frosting.
• Let the green gelatin set completely before placing the second cake layer on top, or it’ll ooze out during frosting.

Variations

• Red velvet spider: Use red velvet cake mix instead of white for a blood-red interior that looks even more dramatic when sliced.
• Orange gelatin: Swap green for orange-flavored gelatin for a more traditional Halloween color scheme inside.
• Pretzel legs: Use chocolate-covered pretzel sticks instead of licorice for crunchier, sturdier legs.
