Let me show you how I’ve made this Sponge Bob cake.
First, make your rectangle shaped cake.
Roll yellow fondant and cover 2/3 of cake.
Use several ball tools and make holes in the cake, to make it look like sponge.
Roll some brown fondant, and cover the last third of the cake.
Transfer the image of Bob’s face on piece of baking paper and cut details out of fondant…
…mouth and tongue.
Cut a white stripe for Bob’s shirt,
and cut two triangles for collar.
Cut few stripes out of black fondant for belt.
Add to small brown balls for legs.
Make black shoes.
Cut red tie.
Now, just add everything on the cake.
Glue the eyes, ad eyelashes.
Add more holes if needed.
Make cheeks with some red fondant.
