SpongeBob SquarePants is a cartoon television character hailing from the fictional oceanic town of Bikini Bottom. Children and parents will recognise this yellow sponge-shaped cake wearing signature brown trousers and a wide, toothy grin. Arrange SpongeBob along with his best pal, Patrick the starfish, and SpongeBob's pet snail, Gary, for a child's Bikini Bottom-themed birthday party. Or, bake this cake for your next ocean-related event to bring a bit of cheer to your dessert table.

    Stack SpongeBob

  1. 1

    Place three loaves of pound cake in the freezer for 30 minutes. Remove the cakes and shave the mounded top of the loaves off with a serrated knife so you have flat surfaces necessary for stacking the cakes.

  2. 2

    Place a loaf of cake upright in the centre of a cake board. Smear 1 tbsp of white frosting on the top of the cake. Flip a second cake over and stack it evenly on the frosted top of the cake. Add 1 tbsp of white frosting to the top of the second cake and flip the other cake over on top of the second cake.

  3. 3

    Position a wooden skewer in any corner of the top of the stacked cakes, 2 inches from the edge of the cake. Push the wooden skewer through the top of the highest cake all the way through the other two cakes. Repeat with three more skewers and the other three corners of the top cake.

  4. 4

    Form divots in the sides and top of the cake using a melon balling tool to recreate the sponge holes found on SpongeBob. Space the holes out so you have no more than five on the front and back sides and three on the top, right and left sides of the cake.

    Give SpongeBob Some Color

  1. 1

    Mix 2 cups of white frosting with yellow food colouring gel until you reach a bold, yellow shade. Cover the entire cake with the yellow frosting. Place the cake in the freezer for 30 minutes and remove.

  2. 2

    Add two 3-inch diameter solid circles using white frosting to the front side of SpongeBob in the centre and 2 inches from the top. Squeeze a solid circle of black gel icing from a tube in the centre of each of the white circles. Squirt a ring of blue gel icing around the black circles. Add three 1-inch lines, spaced 1 inch apart, extended vertically from the top of each of the white circles with black gel icing for SpongeBob's eyelashes.

  3. 3

    Draw a 4-inch-wide grin on SpongeBob using black gel icing. Paint his signature two front teeth -- 1/2-inch square -- on the black grin using white frosting and a food-grade paintbrush.

  4. 4

    Mix 1/4 cup of white frosting with brown food colouring gel and spread the tinted frosting over the bottom 2 inches of SpongeBob to make his trousers. Add a 1-inch layer of white frosting directly above the brown trousers to create the top of his underpants. Add four 1-inch-long and 1/2-inch-wide black rectangles along the top of the brown trousers, equally spaced apart, to create his belt.

  5. 5

    Draw a 1-inch-long shirt tie using red tubed gel icing down the centre front of the cake starting at the top of the underpants and extending down onto the trousers area.

  6. 6

    Mix 1/4 cup of white frosting with black food colouring gel until you achieve a dark black colour. Frost two cupcakes with the black frosting. Arrange the cupcakes in front of the cake spaced 6 inches apart and 6 inches away from the cake.

  7. 7

    Mix 1 cup of white fondant with yellow food colouring gel and divide into three equal portions. Roll two of the portions of fondant into 6-inch-long sticks. Place each stick in the space between the cake and black cupcakes to give SpongeBob his sea legs.

  8. 8

    Divide the remaining portion of yellow fondant in half and roll out two 4-inch long sticks. Form a four-fingered hand on end of each of the yellow sticks, which are arms. Attach the arms to the right and left side of SpongeBob's body so the palms touch the ground.

Tips and warnings

  • If you do not have a melon balling tool, use an ice cream scoop or even a spoon to create the divots in the cake. Find an image online or among your child's toys of SpongeBob, if necessary, to use as a guide. If SpongeBob is for a birthday, use the cupcakes for the candle holders.
