I have been stumped over my grandmother's apple cake recipe, which I'd like to modify to make it vegan. Has anyone ever replaced FOUR eggs with flax eggs or Ener G? I want to be sure it'll work before I waste a bunch of staples and good apples. The original recipe has a dense, moist pound cake with tons of apples and cinnamon and I make it in a tube pan but,unfortunately,four eggs. Anything else I should add to replace some of the liquid? Aquafaba,maybe?
