Why the swap works
An egg is a remarkably multifunctional ingredient. Its white is mostly water and protein, which coagulates at 60–65 °C to set structure; its yolk is an emulsion of fat, lecithin and protein that adds richness, colour and tenderness. In a cake the egg proteins trap expanding air bubbles and then set to hold the crumb; in cookies the yolk emulsifies fat and sugar for chewiness; in meringue the proteins unfold and bond into a stable foam; and in custards the whole egg thickens smoothly as it coagulates. No single plant ingredient does all of this, which is why the right substitute depends on which job matters most. Binders like flax and chia form gels that mimic the setting of egg white; aquafaba contains plant proteins and saponins that help stabilise foam and can whip like it; apple sauce and banana add moisture and some binding through pectin; and commercial replacers blend starches and leavening agents to approximate the structure egg provides in muffins and cakes. The secret is matching the substitute to the recipe's dominant need rather than looking for a one-to-one replacement.

Best for: meringue, macarons, mousse
Apple sauce
60 g = 1 eggAdds moisture and mild sweetness; reduce sugar slightly.
Best for: cakes, quick breads
Mashed banana
half a banana = 1 eggDistinct flavour — best where banana suits.
Best for: pancakes, loaf cakes
Commercial egg replacer
per pack instructionsPotato and tapioca starch blends behave most neutrally.

Tips
- For egg-heavy recipes, use a tested vegan version
- Adjust leavening only as a tested recipe directs
- Chill batter so starches hydrate before baking
Avoid
- Using banana in delicate vanilla cakes
- Skipping the flax resting time
Three dishes with the swap applied
Vegan chocolate brownies
Replace each egg with 1 tbsp ground flax + 3 tbsp water; rest 10 minutes. The gel mimics the binding of egg white for a fudgy centre.
One-bowl vanilla cupcakes
Use about 60 g unsweetened apple sauce per egg in a suitable cake recipe; adjust leavening only if the tested recipe calls for it.
Aquafaba meringue
Whip 90 ml chilled aquafaba with 1/8 tsp cream of tartar until stiff, then add 100 g sugar gradually. Bake low and slow.
Banana pancakes
Half a ripe banana replaces one egg in pancake batter; adds moisture and a gentle binder without gluten development.
Questions people ask
What replaces eggs in a cake?
About 60 g unsweetened apple sauce per egg can work in moist cakes; flavour, lift and structure may change.
Does aquafaba really make meringue?
Yes. Whip chilled chickpea liquid 8-12 minutes with sugar and acid for stable peaks.
Can I use one substitute for every egg recipe?
No. The best result comes from matching the substitute to the egg's main role in that recipe — binding, leavening, moisture or richness.
Why do my vegan cakes sink?
Common causes include under-baking, too much liquid, weak structure or excess leavening. Check measurements and oven temperature before changing the recipe.
Is aquafaba from any bean okay?
Chickpea aquafaba is most reliable; other bean liquids can work but may taste beany or foam less stably.
How do I replace just the yolk?
For richness use 1 tbsp plant yoghurt, blended silken tofu, or a little avocado per yolk.
Can I make an omelette without eggs?
Yes — chickpea flour batter with black salt (kala namak) for an eggy flavour is the classic approach.

A substitution is not a nutrition guarantee
Choose a replacement for the job the original ingredient performs: binding, aeration, thickening, fat or flavour. A mushroom can imitate a patty's shape while providing much less protein; a nut cream can mimic dairy texture without its calcium or B12 fortification. Check the actual product and the rest of the meal.
Ratios are starting points unless a complete recipe has been tested with that exact replacement. Brand formulation, water content and cooking method change the result. Try a small batch for important bakes, and check soy, nuts, sesame and wheat allergens even when a product is labelled vegan.
