Hi, sorry you didn't get much help here, us raw Mom's are kinda uncommon and busy!
To be quite honest I know birthdays are important to us and fun, but I would not make a cake. Most of them here are delish, but too complex for a baby that young, at one year they should not eat anything that involved. That said if the cake is for friends and family, and not intended for the baby, I would definately recommend the blackforest chocolate cheese cake!!!!
For your baby, cut up some soft fruits and let him/her help themselves while you watch, that is grand fun for a baby that age. If you want it to be special, get a few special fruits, like organic papaya, mango, and I definately recommend avocado! My two little ones can't get enough!
Hope you come back to visit RFC, and check on this thread!
