At the link below is a recipe and photo for a cake my mother used to make
for Easter when all her grandkids would be buzzing around the house.

This came from an old magazine clipping that was among my mother's
collection. It was obviously a recipe developed to promote sales of
Pillsbury products and I'm sure it could probably be improved on for taste.
But the methods given for assembling and decorating this cake are really
quite clever.
