Egg Substitute Calculator
Quick answer: Replace 1 egg with 1 tbsp ground flax + 3 tbsp water for binding, ¼ cup applesauce for moisture, or 3 tbsp aquafaba for lift and whipping — substitutions work best in recipes with 3 eggs or fewer.
There's no single egg substitute — there's the right one for the job. Tell us how many eggs and what they're doing in the recipe, and we'll scale the exact swap: flax for binding, aquafaba for lift, applesauce for moisture.
Substitutes at a glance (per egg)
| Substitute | Per egg | Best for |
|---|
| Ground flax + water | 1 tbsp + 3 tbsp | Binding — cookies, pancakes |
| Chia + water | 1 tbsp + 3 tbsp | Binding |
| Silken tofu, blended | ¼ cup | Dense bakes, quiche |
| Applesauce | ¼ cup | Moisture — muffins, quick breads |
| Mashed banana | ¼ cup | Moisture (adds flavor) |
| Aquafaba | 3 tbsp | Lift, meringue, mayo |
| Baking soda + vinegar | 1 tsp + 1 tbsp | Lift — cakes, cupcakes |
How it works
An egg does up to three jobs in a recipe — it binds, it moistens, and it lifts — and every substitute covers only one or two of them, which is why 'just use a flax egg' sometimes produces a hockey puck. The tool asks what the eggs are doing (a cookie's egg binds; a muffin's mostly moistens; a cake's lifts) and scales the right substitute to your count: seed gels for structure, fruit purées and yogurt for moisture, aquafaba or the soda-vinegar reaction for rise. Above three eggs the recipe is probably built on them — at that point pick a recipe developed egg-free rather than converting.
Frequently asked
What is the best egg substitute for baking?
It depends on the egg's job. For binding, a flax or chia egg (1 tbsp ground seed + 3 tbsp water, rested 5 minutes). For moisture, ¼ cup applesauce or mashed banana. For lift and anything whipped, aquafaba — 3 tbsp per egg.
What is aquafaba?
The liquid from a can of chickpeas. Its proteins and starches behave remarkably like egg white — 3 tbsp stands in for a whole egg, 2 tbsp for a white, and it genuinely whips into meringue.
Do egg substitutes work in any recipe?
They shine in recipes with 1–3 eggs. When eggs are the structure — genoise, chiffon, soufflé, custard — substitutes fall short; look for a recipe developed egg-free instead of converting one.
How do I make a flax egg?
Stir 1 tablespoon of ground flaxseed into 3 tablespoons of water and rest 5 minutes until it gels. Grind whole seeds fresh if you can — pre-ground flax goes bitter with age.
Can I substitute eggs in an omelette or scramble?
Not with these swaps — they're for baking. Egg-style dishes use different bases entirely: crumbled or blended tofu with kala namak (black salt) for the eggy flavor, or chickpea flour batter for omelettes.
Do egg substitutes change the taste?
Flax and chia add a faint nuttiness, banana is unmistakably banana, and applesauce, tofu and aquafaba are close to neutral. In spiced or chocolate bakes, none of them are detectable.
