SpongeBob Squarepants Birthday Cake


I was up for the Challenge. A dear friend wanted a birthday cake for her 4 year old son. She told me he loved SpongeBob Squarepants. I was excited. Nervous…but I knew she knew I was just getting into this cake thing…

Anyhoo, I also knew this cake would be a lot of fun. I wanted to try things I hadn’t tried already. One of which was using rice krispie treats to mold a figure. I wish I would have done this with my daughters Foofa Cake. But oh, well. You bake and you learn right?

SpongeBob cake was a yellow cake with buttercream filling and frosting. I used my favorite yellow cake recipe from Easy enough. The hardest for me was getting the water to be a mixture of blue and green without it looking like I tried to hard.


SpongeBob himself was rice krispies covered in fondant. The sign is actually gingerbread painted with royal icing. I covered the cake with chocolate wafers to act as a fence in which SpongeBob is chilling swimming. However, he does want you to join him in his underwater abyss!


I rolled up some fondant and gumpaste for the border. To get the marble effect I added some of the blue buttercream before I rolled. Neat huh?

Before I forget. I have to tell you about my error. I decided to add Patrick, Spongebob’s sidekick, at the last minute. I molded him out the rice krispies and covered him. It took me a long time to cover hi because of his odd star shape. Anyway, he totally took the shine away from his Sponge friend…so I omitted him. But it was only after a long consideration and alterations to make him work.


Yeah, I pretty much cut him down to nothing before coming up with my final decision to leave him off.

Sorry Patrick. Maybe I should have made a sidekick cake.
