Hi Stephanie, nYou could check out the recipe section of this website. If you don’t find what you’re looking for there, a google search for “pku recipes” will turn up hundreds of recipes. Some of them have phe counts for the recipe, and others you have to figure out yourself, or estimate. I imagine that most of the recipes for cake will involve special order flour or cake mix. I’m not the one to talk to about where to get all that, but you should be able to find a good recipe pretty easily online. nHappy cooking!
