I made vegan snickerdoodles last night. I used this recipe. Although they didn't turn out as tasty as classic snickerdoodles, they are still good. The recipe itself could use a little work. The ingredients list says baking powder, but the directions say baking soda [I used the soda], and it makes about 2 dozen cookies, not 2½. It also says use 3T of dough for each cookie, which makes gigantic cookies, I used about 1½T for each cookie. The first batch I made were too sugary, so I cut it down by ¼C in the second batch. The taste was better, but the consistency was a bit too floury. If I make them again, I'll cut both the sugar and the flour by ¼C.
I've never made any vegan chow before, but I'm under the impression that these problems are probably pretty common when baking without eggs and milk. Corn starch has to take the place of the egg, but it doesn't behave the same in the mix.
