Meet Mermaid, kind of an Ariel-meets-Raggedy Ann.
I have to confess, making this cake took precedent over all other 3-year-old party plans. This is including the ridiculous amount of time I spent wandering the bulk candy aisle at Superstore. And of course, I had to make two giant sheet cakes in order to produce enough cake to make two layers, because I love a cake with a filling. This mermaid wasn't just a pretty face, no she was delish: Vanilla cake; Buttercream frosting; and Joan's filling.
Joan's Pudding Filling
(If you mention this filling to Joan she'll look at you blankly, feigning ignorance due to high sugar content)
1 package instant vanilla pudding
1 cup milk
1 cup sour cream, low fat or regular
Prepare pudding but instead of 2 cups milk use 1 cup milk and 1 cup sour cream.
So good I could eat this straight from the bowl. Actually, I did.
On a related but somewhat awkward note: Mermaid boobs. I went with a discreet smarty bikini-style top with licorice straps. I think it worked.
