Spongebob Cake

Fun cake designs and easy to follow tutorials on how to make a fantastic Spongebob cake!

Spongebob Squarepants is a long time beloved cartoon character who lives in the sea. He resides in the ficticious city of Bikini Bottom with his pals Patrick, Squidward, Gary and several others. The show became popular among kids and adults alike when it premiered on Nickelodeon in 1999. Whether you’re a fan of the cartoon show or not, you have to admit there are some pretty spectacular Spongebob cake designs!

Right here on Sugar Geek Show we have our very own fantastic standing Spongebob Cake tutorial for Premium and Elite Members taught by the amazing Jessa Coline of Abstract Edible Arts! If you’ve got some experience under your belt with cake decorating and are looking to wow, this is the Spongebob cake design for you!

It’s jam packed with incredible detail and amazing techniques to create the overall spitting image look of Spongebob Squarepants complete with a krabby patty! The structure of this cake can be super intimidating but Jessa breaks it down so that anyone can do it!

It looks as though Spongebob literally walked right out of the TV screen doesn’t it? Character cakes can be really hard to make look exactly like the character but Jessa knocked it out of the park and shows you just how to do it.

Stand Out Details

Hand painting, airbrushing, modelling work and more really bring the details to life and give them that extra bit of realism and dimension they need to stand out among other cakes.

I especially love his adorable little outfit and the details in his striped socks and shiny black shoes!

The krabby patty is just as impressive in my book! Look at that detail! Patty, cheese, lettuce and a perfectly toasted bun. When you bite into this burger though you’ll be tasting nothing but sweet. If you’re interested in making a super realistic giant burger cake we have that here on Sugar Geek Show too.

Spongebob Cake Ideas

While we are of course partial to our own Spongebob cake design, there are certainly lots of other Spongebob cakes worth checking out! Here are some of our favorites.

The two dimensional work on this cake is absolutely fantastic! I want to say it looks like outlining and flooding with royal icing just like you would do on a cookie. It gives it such a unique look and it really pops.

If you’re not quite sure about attempting a standing Spongebob cake just yet then a sitting design like this cake would be perfect! Add in the details and you’ve still got a super cute cake that emulates the character perfectly.

This tiered Spongebob cake is so fun. I love the cute under the sea detail including Spongebob’s pineapple house. The Spongebob and Patrick toppers

are also really well done! This is another great design idea for anyone looking for something other than a full on Spongebob cake.

Easy Buttercream Frosting

Delicious, rich and easy buttercream frosting recipe that anyone can make. This is not a crusting buttercream. It is meringue based so it has a slight shine and chills nicely in the fridge. Takes 10 minutes to make and is fool-proof! Light, fluffy and not too sweet.

Prep Time: 5 mins
mixing time: 20 mins
Total Time: 10 mins
Serves: 6 cups
Calories: 849kcal


  • 24 oz (680 g) unsalted butter room temperature. You can use salted butter but it will affect the taste and you need to leave out additional salt
  • 24 oz (680 g) powdered sugar sifted if not from a bag
  • 2 tsp vanilla extract
  • 1/2 tsp salt
  • 6 oz (170 g) pasteurized egg whites room temperature
  • 1 TINY drop (1 TINY drop) purple food coloring (optional) for whiter frosting


  • Place egg whites and powdered sugar in a stand mixer bowl. Attach the whisk and combine ingredients on low and then whip on high for 1 minute to dissolve the powdered sugar 
  • Add in your salt and vanilla extract
  • Add in your butter in chunks and whip with the whisk attachment to combine. It will look curdled at first. This is normal. It will also look pretty yellow. Keep whipping. 
  • If your buttercream looks curdled, remove about 1/3 cup of buttercream and melt it in the microwave for 10-15 seconds until JUST barely melted. Pour it back into the whipping buttercream to bring it all together.
  • (Optional) Add your drop of purple food coloring. Whip on high with the whisk attachment for 8-10 minutes until it's very white, light and shiny. Taste the buttercream, if it tastes like sweet ice cream then it's ready!
  • Switch to a paddle attachment and mix on low for 15-20 minutes to make the buttercream very smooth and remove air bubbles. This isn't required but if you want really creamy frosting, you don't want to skip it.
