It is hard to believe a box cake, especially Duncan Hines Moist Deluxe Dark Chocolate Fudge, is vegan…but it is.
I use Ener-G-Egg Replacer to substitute for the eggs.
One thing, don’t try to get fancy and make a layer cake. I’ve found while a 9×13 works, my vegan layer cakes never hold up. They fall a bit and get gummy. I’m going to overcome, and I will give you the secret recipe as soon as I find it, but make do with a 9×13 until then.
