My son wanted a shark-theme party for his 7th birthday. My husband and I baked two 13X9 yellow cakes and cut out a square hole in one for the shark-infested “water.” We put the shark in a square plastic dish and poured blue Jell-O in around him and let it set.
When the Jell-O was ready, we set the whole dish into the hole we’d made and frosted the cakes and the side of the plastic dish so it all blended well. We even added some “white caps” to the water. We used our son’s toy kayak, fisherman, and fishing pole to make it look like the fisherman had caught the shark.
The kids LOVED the Fishing Birthday Cake – and even fought over the blue Jell-O!
