My son's 3rd birthday party was SpongeBob themed! I made white cake cupcakes (with SpongeBob cupcake wrappers of course) and iced them with 2-tone buttercream icing. Each cupcake is topped with white chocolate seashells/coral, sprinkled with brown sugar for sand and a few Nerds candy for rocks & a splash of color. Starfish painted with gold luster dust. The birthday boy had a special cupcake with his name and '3' in white chocolates instead of shells. Fun!
