How to substitute eggs in baking
Eggs do four different jobs in baking. Picking the right substitute starts with knowing which job matters in your recipe.

What eggs actually do in baking
Eggs play four roles: binding (holding the batter together), leavening (lift), moisture (tender crumb), and richness (flavor and color).
A good substitute matches the dominant role. Picking 'one substitute fits all' is why egg-free baking sometimes goes wrong.
Best substitutes by role
Binding (cookies, brownies): 1 egg = 1 tablespoon ground flax + 3 tablespoons water, mixed and rested 5 minutes.
Moisture (muffins, quick breads): 1 egg = 1/4 cup unsweetened apple sauce or 1/4 cup mashed ripe banana. Banana adds flavor; apple sauce is neutral.
Lift (cakes, soufflé-leaning): 1 egg = 1/4 cup aquafaba (chickpea brine) whipped if the recipe needs structure.
What doesn't substitute well
Anything custard-based (lemon curd, pastry cream, crème brûlée). The whole structure depends on egg proteins setting — there's no good vegan analog.
Meringues need aquafaba specifically; flax and apple sauce will fail.
People also ask
Will the texture be the same?+
Close, not identical. Vegan brownies are slightly fudgier; vegan cakes are slightly denser. Most people don't notice.
Can I use commercial egg replacers?+
Yes — Bob's Red Mill, JUST Egg, etc. They're consistent and easy. Pricier than DIY.
How many eggs can I sub before the recipe falls apart?+
Up to 2 reliably. 3+ eggs = the recipe is structured around eggs and substitutes will struggle.
