We're having a baby luau for my daughter's first birthday and I'd like to get a cake flavored with guava, passion fruit, mango, or something tropical (no coconut) to fit the luau theme. We live in the Berkeley area and I'd prefer not to have to battle commute traffic all the way down to Aki's in San Jose for their guava chiffon (although it is sooo yummy!). I've called around to several bakeries already with no luck. Does anyone know of a bakery or caterer in the SF-Oakland-Berkeley vicinity that does a tropical-flavored cake? Thanks in advance for your ideas!
