You kind of buried the lede. Obviously the pancakes are going to turn out differently than traditional pancakes if you sub out like half the usual ingredients.

I mean, apple sauce instead of egg works wonders. (Or banana if you like the flavor. Or pumpkin. Or plenty of things. Bob’s red mill makes an egg substitute that works fine too.) Make sure if you’re using baking soda you add some lemon juice or some acid of some kind to activate it (apple sauce generally does that but other egg subs won’t.)

I have used off the shelf vegan mix. The one I had needed milk (substitute) added to it. Maybe you need to do that rather than add water?

Do you not add an egg to it? I've tried using mashed banana instead which sort of works but still isn't as good.

Not Milk or Next Milk sub in well for regular milk
