Per the Birthday Girl's Request . . . a Rainbow Cake
"I knew a rainbow cake would be perfect for the celebration, and I thought she would like that more than her request for a vegetable cake (what's that?)," said Rubyellen. "I baked the cake the night before we left home, using a Martha Stewart recipe, wrapped each layer in saran wrap separately, and froze it all. Then, when it was time to put it together, it was easy-peasy. This was all a surprise to her, so you should have seen her face when she came back to the room."
