Best Egg Substitutes for Baking (With Ratios)
The best all-round egg substitute for baking is a flax egg: stir 1 Tbsp (7 g) ground flaxseed into 3 Tbsp (45 mL) water and let it gel for 5–10 minutes. It replaces one large egg (about 50 g out of the shell) in muffins, cookies, pancakes and quick breads.
Egg substitutes and ratios
| Substitute | Amount per 1 large egg | Best for | Why it works |
|---|---|---|---|
| Flax egg | 1 Tbsp ground flax + 3 Tbsp water | Muffins, cookies, quick breads | Mucilage gel binds like egg protein |
| Chia egg | 1 Tbsp chia seeds + 3 Tbsp water | Same as flax; dense loaves | Similar gel, slightly firmer |
| Aquafaba | 3 Tbsp (2 Tbsp per white) | Meringues, macarons, light cakes | Chickpea proteins and starches foam and set |
| Unsweetened applesauce | 1/4 cup (60 g) | Moist cakes, brownies, quick breads | Pectin holds water; adds moisture |
| Mashed ripe banana | 1/4 cup (55 g) | Banana bread, pancakes, muffins | Starch and pectin bind; adds flavour |
| Plain yogurt | 1/4 cup (60 g) | Cakes, muffins | Protein and moisture; acid helps baking soda |
| Silken tofu, blended | 1/4 cup (60 g) | Dense cakes, brownies, quiche-style bakes | Soy protein sets with heat |
| Vinegar + baking soda | 1 Tbsp vinegar + 1 tsp baking soda | Light cakes and cupcakes | Replaces eggs' lift with carbon dioxide |
| Commercial egg replacer | As per package | Cookies, general baking | Starches and leaveners blended for the job |
What eggs actually do
An egg is about 75% water, 12% protein and 10% fat, and it does several jobs at once:
- Structure. Egg proteins denature and coagulate between about 62 and 80 °C (145 and 175 °F), setting the crumb.
- Emulsifying. Lecithin in the yolk keeps fat and water blended for a smooth batter.
- Leavening. Beaten eggs trap air that expands in the oven.
- Moisture and browning. Water turns to steam, and proteins feed the Maillard reaction.
No single swap copies all four. Flax and chia gels bind well but don't lift. Fruit purées add moisture but make the crumb denser. Vinegar and baking soda lift but don't bind. Pick the swap that matches the egg's main job in your recipe.
When not to swap
- Egg-heavy recipes. Custards, soufflés, sponge cake, chiffon, flan and quiche rely on many eggs and won't set properly with swaps.
- Angel food cake. It needs about a dozen whites; even aquafaba gives a shorter, gummier cake.
- Enriched breads like brioche and challah. The yolks give richness and colour that purées can't.
- Glazes and egg washes. Brush with milk, cream or a little maple syrup thinned with plant milk instead.
- Expect shorter bakes to run long. Purée-based swaps hold more water, so add 3–5 minutes and test with a toothpick.
Questions
How many eggs can I replace in a recipe?
Most egg substitutes work well for one or two eggs. Once a recipe uses three or more, the eggs are doing structural work that swaps struggle to copy, so look for a recipe written to be egg-free.
What replaces egg whites?
Aquafaba, the liquid from a can of chickpeas. Use 2 Tbsp per egg white; it whips into stable peaks for meringues and macarons.
Can I use applesauce instead of eggs in brownies?
Yes, 1/4 cup per egg, but brownies turn more cakey and moist and less fudgy. For fudgy brownies, a flax egg or a commercial egg replacer is better.
Does a flax egg taste like flax?
Slightly nutty, but in spiced, chocolate or whole-grain baking it is nearly undetectable. Golden flax is milder and less speckled than brown.
