Ingredients
Scale
Cake
- 1 box yellow cake mix (plus eggs, oil, and water as per package instructions)
Buttercream Frosting
- 1 cup butter (softened)
- 4 cups powdered sugar
- 2–3 tablespoons milk
- 1 teaspoon vanilla extract
- Yellow food coloring
Decorations
- Black, white, blue, red, and brown fondant or icing (for facial features and outfit)
- Optional: edible eyes or candy eyes
Instructions
- Prepare the Cake: Follow the directions on the yellow cake mix box, including adding eggs, oil, and water as listed. Pour the batter into a rectangular baking pan. Bake as directed until a toothpick inserted in the center comes out clean. Allow the cake to cool completely before frosting.
- Make the Buttercream Frosting: In a mixing bowl, beat the softened butter until creamy and smooth using a hand mixer or stand mixer. Gradually add the powdered sugar while continuing to beat. Stir in vanilla extract and add milk one tablespoon at a time until the buttercream reaches a smooth, spreadable consistency. Mix in yellow food coloring until the frosting is evenly tinted.
- Frost the Cake: Evenly spread the yellow buttercream frosting over the entire surface of the cooled cake using an offset spatula. Smooth the frosting as much as possible to create a flat canvas for decoration.
- Create SpongeBob’s Features: Using fondant or colored icing in black, white, blue, red, and brown, carefully sculpt or pipe SpongeBob’s eyes, nose, mouth, tie, shirt, and pants on top of the frosted cake. Place edible or candy eyes if using to enhance the details. Take your time to match the classic SpongeBob SquarePants look.
- Add Final Details: Use black icing or a food-safe pen to draw finer features such as eyelashes and freckles, ensuring the cake captures SpongeBob’s personality perfectly.
Notes
- Ensure the cake is completely cooled before frosting to prevent melting the buttercream.
- If fondant is not available, use colored icing and piping techniques to create the decorations.
- Use an offset spatula for smoother frosting application.
- Refrigerate the cake if not serving immediately, but bring to room temperature before serving for best texture.
- Optional edible eyes can add a fun 3D effect to the cake design.
