Make a fish cake with one round cake and cupcakes. It's like the rainbow fish book. So cute for a kids birthday!
Homemade Fish Cake: This fish cake was made for my uncle who loves to fish and who my children named Fishing George instead of Great Uncle George. I used a cake mix and made
John Deere Cupcake Tractor for the little men in my life. or RED tractor.
Homemade Fish Birthday Cakes-- I'd adapt this for the rainbow fish theme.
