Spongebob Cake Ideas

I made a box cake mix from the store followed the directions on the back. Then to decorate it I made buttercream frosting and tinted some of a water blue color and frosted the whole thing.

Next, I took some graham cracker and crushed them to make them look like sand. I used some palm trees that I bought from my local cake supply store as well as the Spongebob and Patrick editable sugar.

I also used some of the colored goldfish crackers for the sides of the cake to make it look like they were in the water. I gave Spongebob and Patrick tubes to float in.

The cake was a great hit and the kids all loved it.

SpongeBob Birthday Cake

This is a chocolate cake with a chocolate mousse filling and buttercream icing.

Ingredients:

  • 2 cups sugar
  • 1 3/4 cup all-purpose flour
  • 3/4 cup cocoa or special dark cocoa
  • 1 1/2 tsp. baking powder
  • 1 1/2 tsp. baking soda
  • 1 tsp. salt
  • 2 eggs
  • 1 cup milk
  • 1/2 cup vegetable oil
  • 2 tsp. vanilla
  • 1 cup boiling water

Preheat oven to 350°F. Grease and flour baking pan(s).

Stir together sugar, flour, cocoa, baking powder, baking soda and salt in a large bowl. Add eggs, milk, oil and vanilla.

Beat with electric mixer on medium speed for about 2 minutes. Stir in boiling water (batter will be thin). Pour batter into prepared pan(s).

Bake 30-35 minutes for round pans and 35-40 minutes for rectangular pans, or until wooden pick inserted in center comes out clean. Let the cake cool completely.

I put my cakes in the fridge overnight.

Chocolate Mousse Filling:

  • 1 tsp. unflavored gelatin
  • 1 Tbsp. cold water
  • 2 Tbsp. boiling water
  • 1/2 cup sugar
  • 1/4 cup cocoa
  • 1 cup cold whipping cream
  • 1 tsp. vanilla

Sprinkle gelatin over cold water in small bowl. Let stand for 1 minute to soften. Add boiling water. Stir until gelatin is completely dissolved and mixture is clear. Cool slightly.

Stir together sugar and cocoa in medium bowl. Add whipping cream and vanilla. Beat at medium speed scraping bottom of the bowl occasionally until stiff. Pour in gelatin mixture and beat until well blended. Refrigerate for 1/2 hour.

Buttercream frosting:

  • 1 cup shortening
  • 1 tsp. clear flavorings of your choice (I use 1/2 tsp. of butter flavoring and 1/2 tsp. vanilla flavoring)
  • 4 Tbsp. water
  • 1 Tbsp. meringue powder
  • 4 cups confectioner's sugar

Cream shortening, water and flavorings. Combine meringue powder and sugar. Add sugar mixture to shortening, and mix until well blended. Do not mix at a high speed, this will cause air in the frosting.

For this SpongeBob cake, you will need two full recipes of the buttercream frosting.

I made a 9x13 cake, torted it, and added the mousse filing. I then iced the cake with the buttercream frosting tinted blue.

I used a piping gel transfer method for Patrick. I found a picture of Patrick, and traced the picture with piping gel (in a parchment bag).

I then laid the piping gel tracing onto the cake. I used several round tips to fill in Patrick with a thin buttercream frosting. I piped Happy Birthday with a round tip. Piped the blue background with round tips (freehand).

SpongeBob was done using the color flow method. I traced a picture of SpongeBob onto parchment paper, then covered the parchment paper with waxed paper.

I outlined SpongeBob in the appropriate colors, and then filled in with color. I let it sit overnight to dry. I added a small amount of leftover buttercream frosting.

I then added pink jelly fish. The border was just a shell border using tip 21.

Spongebob Cake

I do not really have any baking history except just for at home and for my kids. Basically just done these off of my creativity.

First off I made 2 cake mixes and then placed them in a large rectangular pan and made another cake mix and placed 1/2 of that into a pan that has the shape of a 2 and the rest into a small square pan. I also made another cake mix and made 24 cupcakes.

After the cakes were baked I flipped the rectangular one onto the platform that I would be using. Then really just using my eye technique cut out the humps to where the number '2' would be placed.

From the extra square cake I cut 4 pieces that were about 1/2 inch by 2 1/2 inch for the feet and legs them I cut two more pieces that were about 2 by 2 inches which would be the shorts of SpongeBob. I also cut another 1 by 1/2 for the sleeve and another pice that was about 1/2 by 2 inches shaping a little bit for the hand area.

After that I got one vanilla frosting can (ready made), added yellow food coloring and put over the top 3/4 the cake. Also with that same yellow did the lower legs and the arm/hand.

On the lower part I put about 1/4 of the remaining area white which is the shirt and the rest. Rhe 2 smaller pieces I covered in chocolate frosting making that the shorts and thighs. After that I just made some blue food coloring and covered the '2'.

after all that was done you pretty much have SpongeBob cake finished. The only thing that is needed is detailing and the feet. For those, I basically just free handedly drew everything paying detailed attention to drawing the eyes, nose, eye lashes, mouth, tongue, teeth, tie, shirt, belt, shoes.

For the jelly fish, I just covered with strawberry frosting, drew on the shape of the jellyfish with white frosting then added 3 small globs on the left upper part of the jelly fish. And for the tentacles of the jelly fish, I just inserted small cut pieces of strawberry Twizzler candies.

SpongeBob Squarepants Cake

This is the cake I made for my son's 3rd birthday. He loves Sponge Bob, and I didn't want to just make a plain Sponge Bob cake. So I decided to make this.

The first step was to bake 2 cakes in my 13" round cake pan, 2 cakes in my 9x9" square cake pan, then 4 or 5 cakes in my 6x2" cake pan.

Let them all cool. Then I put one 13" round down, and frosted the top with buttercream. Then I put the next 13" round on top of it, frosted both in a sea green/turquoise.

I took my two 9x9" cakes and centered them on the top of the 13" base. Then frosted them with the same color.

I took my 6x2" cakes and carved them to resemble a pineapple shape. I secured them with wooden dowels on top of the cake. Frosted it with a yellowish/orange color, then took orange frosting to make the diamond/lines on the pineapple.

I made some blue frosting to do the trim work, door and window. I bought the sugar fish, seaweed, and turtles at my local grocery store. And I bought the Sponge Bob and Patrick characters online.

I made the pineapple leaves out of green card stock. Taped them to toothpicks and stuck on the top.

I made the buttercream with 2 cups shortening, half stick of butter, 1 tbsp vanilla. Then just kept adding confectioner's sugar and milk until it tasted the way I liked. (I never measure, I just kind of eyeball it, then just keep tasting.)
