has anyone tried doing the same thing with pound cake mix??? I have a great-niece turning 2 this weekend and just recently found out she's allergic to milk and eggs. I was planning on using a pound cake mix to make her a "fish tank" cake. Anyone have any suggestions????

ANYONE???????

I think you can do it with pound cake but you would use a 'light coloured' pop like Sprite or Mountain Dew.
