The great granny cake contest!

"Can you keep a secret? Pandora's granny is a witch! She causes magical mayhem wherever she goes. In these stories, she brings comic chaos to a televised baking competition, delightful disaster to a school fair, and tons of trouble to a stately home! But she makes everything right in the end, with a bit of help from Pandora. Everyone loves Granny, especially her long-suffering granddaughter!"--OCLC.
