Birthday Spongebob Cake Baking Instructions

For Pineapple Cake

  • First, preheat the oven to 350 degrees. Line up the 2-quarter sheet pans with parchment paper, and grease with non-stick cooking spray, or some butter.
  • Spray generously with non-stick cooking spray and place 2 flower mails upside down into the pans.
  • Now, mix all the dry ingredients together ( flour, baking powder, sugar, and salt)in a mixer until fully combined.
  • Now slowly and gradually mix butter (room temperature) with the dry ingredients. Continue to mix until no large chunks of butter remain, and the batter becomes crumbly.
  • Add egg whites, and whisk on low speed until just incorporated. Add pineapple juice, then buttermilk, and mix until combined properly into a smooth batter.
  • Scrape down the sides of the bowl with a spatula, then beat for about 30 seconds on medium speed. Mix in vanilla and oil at low speed until fully combined.
  • Now divide the batter equally in each pan.
  • To ensure the layers bake to the same height, use a digital kitchen scale to weigh the pans.
  • Bake the cakes for 34-36 minutes, or until a toothpick comes out clean. Cool the pans for 10 minutes, then run an offset spatula around the perimeter to release the cake.
  • The cake layers must be frozen for 30 minutes to accelerate the cooling process. Once the layers have cooled, carefully flip them over and remove them from the pans.
  • Once the layers have cooled completely, level the tops and cut each layer into three rectangles (8 in. x 4.33 in.).

For Pineapple Syrup

  • Using a saucepan, combine pineapple juice and granulated sugar and heat over medium-high heat.
  • Stir occasionally until the mixture boils.
  • Remove from heat, and let cool.
  • Set it aside for 30 minutes.

For Buttercream Frosting

  • Make the vanilla buttercream frosting while the cake layers bake and cool.
  • Beat the butter with a paddle attachment for 30 seconds until smooth.
  • Slowly add the powdered sugar, 1 cup at a time, alternating with a splash of cream.
  • Incorporate the vanilla and salt after the mixture is fully mixed, and beat on low until the consistency is reached.
  • A teaspoon of cream or a quarter cup of powdered sugar can be combined to achieve the desired thickness. If the frosting is too thin, add in additional cream (1 teaspoon at a time).
  • Make your chocolate frosting by placing 12 cups of uncolored frosting into a piping bag, cut a 12-inch opening at the end, and set aside.
  • Make your uncolored frosting by placing 12 cups of frosting into a separate bowl, and mixing in 1 teaspoon of cocoa powder. Place this chocolate frosting in another piping bag, cut a 1-inch opening, and set aside.
  • Add the yellow food gel color to the remaining frosting.

  • Smooth the top 3/4 of the cake with a bench scraper after adding a second, thicker layer of frosting.
  • Smooth using an acetate sheet and a bench scraper after you have outlined the yellow with a white line.
  • The facial features, tie, belt, and shoes of SpongeBob can be made from fondant.
  • Put a small amount of fondant on each leg and arm of SpongeBob, and gently press it onto the buttercream Pipe.
