How to Decorate a Spider-Man Cake

by Tonya Staab

All you need is a basic cake, a few supplies, and you can make a fantastic Spider-Man cake in no time at all with these tips. 

Last week my oldest (you know, the one who recently moved out of home, sniff) asked me to make a birthday cake for his girlfriend.

All I knew is she loves red velvet cake and Spider-Man.

I would love to share a fabulous red-velvet cake recipe with you, but things have been busy lately. I didn’t have time to experiment in the kitchen as I would normally do and I don’t have a tried and true recipe on hand for red velvet cake. So, I made this cake using a couple of boxes of cake mix, substituting the oil for apple sauce, and then made my own vanilla icing.

This cake took two boxes of red velvet cake mix which I divided between three 8″ round cake pans.

What you need

  • 3 8″ round cake pans (or just bake each layer separately to re-use the one pan
  • 2 box red velvet cake mix
  • Vanilla frosting
  • Applesauce (for cake mix instead of oil)
  • Butter and flour (for greasing the pan)
  • Red nonpareils
  • Spider-Man toy
  • Parchment paper
  • White chocolate
  • Wilton piping tip No.2
  • Piping bag
  • Black edible food spray


Preheat the oven, and then follow the cake mix instructions substituting the oil for applesauce.

I don’t normally use baking paper in cake pans. Instead, I grease them by brushing melted butter around the base and sides and then shake flour over the top, moving the pan around until all of the butter is covered in a thin layer of flour. I then shake the excess out.

I didn’t know if she liked fondant and didn’t want to run the risk of her hating it so I decided against doing a tiered Spider-Man cake. Instead, I put icing between each of the cake layers, leveling each of them with a knife before stacking them. I then did two layers of icing around the outside – a crumb layer which I refrigerated until firmer and then added a top layer.

I then added red sprinkles to the top of the cake and a Spider-Man candle.

Edible spider webs

To make the webs I drew spider webs on a piece of parchment paper in various sizes, turned it over and piped melted white chocolate over the top using a piping bag with a No.2 Wilton tip. The white chocolate was set in the refrigerator and then sprayed with black edible color. I didn’t want it to look perfect so sprayed some webs with a second coat and others with a very light coat.

Unfortunately, some of the webs began breaking as they softened which I actually decided made them look more realistic because I was able to place broken pieces of webs around Spider-Man.

She was thrilled with her cake. And I’m so glad I was able to put smiles on both of their faces.

The spider webs would be perfect for a Halloween cake.

If you have a child who celebrates their birthday around Halloween and are looking for a party theme, then this is perfect. Kids love superheroes, and what could be better than adding the ‘spider’ touches to make it a kid-friendly Halloween party.
