My SIL is allergic to gluten, dairy, tree nuts AND soy! It has been a great learning experience. I had a head strat because one of my daughters was vegan - but she ate soy products. But, after researching, I have found a lot of recipes. An easy out is Bob's red mill products. The have a great cake mix and a brownie mix (bonus, they actually taste good to folks who eat 'regular' desserts). And, for a treat, Sprouts and Lassens carry a cheescake that meets all our requirements! Just thaw and eat!
