Egg Substitute for Cake

Written by · Updated August 13, 2026

For cakes you want moisture and tenderness. Here are the egg swaps that keep cake soft, with amounts per egg.

Flax egg vegan

1 tbsp ground flaxseed + 3 tbsp water

For 1 egg · Binding

Mix and rest 5 minutes until gel-like. Adds a subtle nutty flavor; a reliable all-rounder.

Chia egg vegan

1 tbsp chia seeds + 3 tbsp water

For 1 egg · Binding

Like a flax egg; gels in 5–10 minutes. Leaves tiny specks.

Unsweetened applesauce vegan

1/4 cup unsweetened applesauce

For 1 egg · Moisture

Great for moist, tender bakes. Reduce other sugar slightly; not for structure-heavy recipes.

Plain yogurt

1/4 cup plain yogurt

For 1 egg · Moisture

Adds moisture and a little tang. Use dairy-free yogurt to keep it vegan.

Blended silken tofu vegan

1/4 cup silken tofu, blended smooth

For 1 egg · Structure + moisture

Neutral flavor; good for dense, fudgy bakes. Blend until completely smooth.

Aquafaba (chickpea brine) vegan

3 tbsp aquafaba

For 1 egg · Leavening / airy

Whips like egg whites, the go-to for meringues and light, airy bakes.

Baking soda + vinegar vegan

1 tsp baking soda + 1 tbsp vinegar

For 1 egg · Leavening

Creates lift for light, fluffy cakes and cupcakes. No binding power.

Commercial egg replacer vegan

1 1/2 tsp egg-replacer powder + 2 tbsp water

For 1 egg · All-purpose

Follow the package, but roughly this per egg. Consistent across most recipes.

Cake is more delicate than cookies, so an egg substitute needs to balance moisture and lift. For a single egg, a quarter cup of unsweetened applesauce or plain yogurt keeps the crumb tender, while a teaspoon of baking soda whisked with a tablespoon of vinegar helps the cake rise and stay light. For richer cakes, a quarter cup of silken tofu blended smooth adds structure without a strong flavor of its own.

Because cakes depend on a soft, even crumb, avoid overmixing once the substitute goes in, and don't lean only on heavy purées for cakes that call for several eggs, or the texture turns dense. A good approach is to combine a moisture swap with a leavening swap so you get both tenderness and rise. Choose your cake type and the number of eggs above to get the amount that fits, whether it's a light layer cake or a denser pound-style bake.

How to replace eggs in baking

Eggs do different jobs, binding, moisture and leavening, so the best substitute depends on what you’re making. Pick your recipe type above to see the swaps that work, with the exact amount per egg.

Which substitute for which job?

  • Binding (cookies, muffins, breads): flax or chia egg.
  • Moisture (cakes, brownies, quick breads): applesauce, mashed banana or yogurt.
  • Leavening / airy (meringues, light cakes): aquafaba, or baking soda + vinegar.
  • All-purpose: a commercial egg replacer is the most consistent.

Most substitutes work well up to 2–3 eggs. Beyond that, recipes that rely heavily on eggs (like sponge cakes) are harder to convert.

Frequently asked questions

What is the best egg substitute for cake?

For a tender, light cake, applesauce or yogurt for moisture paired with a baking-soda-and-vinegar reaction for lift works well. Silken tofu is a good choice for richer, denser cakes.

How many eggs can I replace in a cake recipe?

Replacing one or two eggs is usually reliable. Cakes built on three or more eggs depend heavily on them for structure, so they turn out best with a recipe designed to be eggless.
