More Great Good Desserts Naturally is a wonderful place to start (it includes the best recipes from her earlier book). Fran Costigan is a vegan cake maven, for sure! =) I like that her cakes are just sweet enough, without being cloyingly over-sweetened...and they don't taste like they came from a health-food store! I've gotten fabulous responses from non-vegan friends/family. I made the "Chocolate Cake to Live For" for my husband's non-vegan cousin's birthday (I also filled it with some berries cooked down in just a touch of maple syrup and cinnamon) and the cousin and aunt said it was the best chocolate cake they'd ever had!
(Disclaimer: I haven't tried her non-cake recipes.)
