I'll let everyone know if I get a chance to try it out! I'm not 100% positive about the applesauce + baking powder as an egg replacer, but it should work. That mix is good for replicating the fluffiness with a little bit of binder, but of course it provides a very different flavor. Follow Your Heart just came out with a full egg replacer that is supposedly pretty good, but getting a good egg replacer that performs all of the functions that egg can serve from common ingredients can be tricky.

If you're a vegan who eats honey (some do), adding a little bit of honey would give it some extra binding. Same thing with maple syrup.
