For my niece's birthday, my daughter and I created this SpongeBob SquarePants cake with SpongeBob and Patrick sitting at a table in the Krusty Krab sharing a Krabby Patty.
The table and floor was cake covered in fondant. SpongeBob and Patrick were made using Rice Krispies Treats covered in fondant. The top of the table was chocolate. The Krabby Patty was also made with Rice Krispies Treats covered in fondant.
