This Spongebob Squarepants birthday cake was super fun to make. It had an underwater theme and was decked out with Spongebob himself.

Spongebob Squarepants Birthday Cake Details

  • The cake was two tiered and covered with mixed fondant colors to create a wavy appearance.
  • The shells and waves were made from Wilton molds.
  • Spongebob Squarepants was constructed entirely by hand out of a Rice Krispies treats and covered in fondant pieces.
  • When complete, he was placed on the edge of the bottom tier.

This was my first time making anything like this and I’m not going to lie; it was terribly frustrating at first.

The payoff was completely worth it, though. The cake was for a young girl’s birthday and she cried with excitement when she saw it!

This was one of my favorite cakes I have ever made by far.
