Egg Substitutes in Baking
Updated August 15, 2026
The most reliable all-purpose swap is a flax egg: 1 tablespoon ground flaxseed whisked with 3 tablespoons of water, rested 5 minutes, per egg. For lighter bakes, 3 tablespoons of aquafaba (chickpea-can liquid) per egg; for dense, moist bakes, ¼ cup applesauce or mashed banana.
| Substitute | Amount | Best in |
|---|---|---|
| Flax (or chia) egg | 1 tbsp ground seed + 3 tbsp water, rest 5 min | Cookies, muffins, pancakes, quick breads |
| Aquafaba | 3 tbsp (whips like whites) | Meringues, macarons, light cakes |
| Applesauce | ¼ cup | Moist muffins and snack cakes |
| Mashed banana | ¼ cup | Banana-friendly bakes — it will taste of banana |
| Yogurt | ¼ cup | Cakes and muffins needing richness |
| Commercial replacer | Per box | The most neutral, most consistent option |
Know which job the egg was doing
Eggs do three different jobs — binding, lift, and moisture/richness — and each substitute covers a different subset. Flax binds beautifully but adds no lift; aquafaba whips into a genuine foam, which is why it can even make meringue; fruit purées add moisture and slight binding while making the crumb denser. Match the substitute to the bake: a chewy cookie wants a binder, a sponge cake wants lift, a snack cake mostly wants moisture.
Where substitutes hit their limit
One or two eggs in a sturdy batter substitute cleanly. Recipes built ON eggs — custards, pastry cream, chiffon and angel food cakes, anything with six yolks — don't convert with a swap; they need a recipe developed eggless from the start. A useful rule: if eggs are more than a third of the recipe's structure, find a vegan version of the recipe instead of substituting into the original.
Quick answers
- What's the best all-around egg substitute?
- The flax egg — 1 tbsp ground flax + 3 tbsp water per egg. Neutral enough for most bakes and binds nearly as well as the real thing.
- What is aquafaba?
- The liquid from a can of chickpeas. Its proteins whip like egg whites: 3 tbsp ≈ one egg, and it genuinely holds peaks for meringue.
- Can I just leave the egg out?
- In a pancake or one-egg cookie recipe, sometimes — add 2–3 tbsp of extra liquid. In anything relying on structure, skipping it shows up as crumbly and flat.
