The most common egg replacements and how they work

Eggs bind ingredients together, add moisture, and help baked goods rise. When you need to replace them, the substitute you choose depends on what role the egg plays in that particular recipe. A cookie needs different support than a cake, and a cake needs different support than a quick bread. The good news is that most kitchens already have at least one working replacement on hand.

The three categories of replacements are binders (which hold dry ingredients together), leaveners (which help baked goods puff up), and moisture providers (which keep them from drying out). Many recipes need all three, so you may use a single substitute that does multiple jobs, or combine two or three different ones.

Key Takeaways

  • Applesauce, mashed banana, and yogurt replace eggs by adding moisture and binding power, though they can make baked goods denser than eggs do.
  • Baking soda mixed with an acid (vinegar or lemon juice) creates lift in the oven the way eggs do, and works best in cakes and quick breads.
  • Flax or chia seeds mixed with water create a gel that binds ingredients and works well in dense baked goods like brownies and muffins.
  • Aquafaba (the liquid from canned chickpeas) whips into foam and can replace eggs in recipes that need airy texture, like angel food cake or meringues.
  • Different recipes call for different substitutes—a dense brownie needs a different replacement than a light sponge cake.

Applesauce, banana, and yogurt for moisture and binding

These three are the easiest replacements because most people have them in the kitchen. Use one-quarter cup of unsweetened applesauce, mashed banana, or plain yogurt per egg. They all add moisture and help bind dry ingredients, but they do not create the same lift that eggs provide, so baked goods will be denser and more compact.

Applesauce works in brownies, muffins, and quick breads without changing the flavor much. Mashed banana adds sweetness and banana flavor, so reduce the sugar in the recipe slightly and use it only in recipes where banana flavor fits—chocolate cakes, oatmeal cookies, and spice cakes work well. Yogurt adds tanginess and works best in recipes that already have some acidity, like lemon cakes or recipes that call for buttermilk.

All three can make the texture slightly gummy if you use too much, so do not exceed the one-quarter cup per egg ratio. These work best in recipes that call for one or two eggs, not in recipes that rely on three or more eggs for structure.

Baking soda and acid for lift and rise

When a recipe needs eggs mainly for leavening—to make the baked good rise and become fluffy—mix one teaspoon of baking soda with one tablespoon of vinegar or lemon juice per egg. Let the mixture sit for a few minutes until it stops fizzing, then add it to your wet ingredients. This combination creates carbon dioxide bubbles that puff up your cake or quick bread in the oven, much the way eggs do.

This method works best in cakes, pancakes, waffles, and quick breads. It does not work well in cookies or brownies, which do not need much rise. The acid in the mixture also reacts with baking soda to create lift, so do not use this method in a recipe that already calls for both baking soda and an acidic ingredient like buttermilk or vinegar—you will end up with too much leavening and a cake that rises too fast and then collapses.

Flax or chia seeds for binding in dense baked goods

Mix one tablespoon of ground flaxseed or chia seed with three tablespoons of water per egg, and let it sit for five to ten minutes until it becomes gel-like. This replacement works well in brownies, muffins, cookies, and dense cakes where you do not need much rise. The seeds add a slightly nutty flavor and a bit of texture, which most people do not notice in chocolate or spice-forward recipes.

Flax and chia are stronger binders than applesauce or banana, so they work in recipes with three or more eggs. They do not add much moisture, so if your recipe is already on the dry side, combine this method with applesauce or another moisture provider. Do not use this in delicate cakes or anything where you want a light, airy crumb—the baked good will be heavier than it would be with eggs.

Aquafaba for whipped texture and airiness

Aquafaba is the liquid left in a can of chickpeas. Three tablespoons of aquafaba replace one egg, and it can be whipped into stiff peaks just like egg whites. This makes it the best choice for recipes that need airiness and structure—angel food cake, chiffon cake, meringues, and mousse.

Whip the aquafaba with an electric mixer for three to five minutes until it forms stiff peaks, then fold it gently into your other ingredients. The result will be lighter and airier than most other egg replacements. Aquafaba does have a faint bean flavor, so it works best in recipes with strong flavors like chocolate, vanilla, or spice. It does not work well in delicate vanilla cakes where the egg flavor is part of the taste.

Cornstarch and arrowroot powder for binding without moisture

If you need binding power without adding extra moisture, mix two tablespoons of cornstarch or arrowroot powder with three tablespoons of water per egg. Let it sit for a minute or two until it thickens slightly, then add it to your wet ingredients. These starches bind ingredients without adding the richness or flavor that eggs provide, so they work well when you want the other flavors in your recipe to shine.

Cornstarch and arrowroot work best in cookies, shortbread, and other recipes where you want a crisp or tender texture rather than a moist crumb. They do not provide any leavening, so use them only in recipes that do not rely on eggs for rise. If your recipe calls for more than two eggs, combine this method with baking soda and acid to get both binding and lift.

Choosing the right replacement for your recipe

The best replacement depends on what the recipe needs. Look at the number of eggs and what role they play. If the recipe calls for one or two eggs and does not emphasize rise or airiness, applesauce or mashed banana will work. If the recipe is a cake that needs to rise and puff, use baking soda and acid. If you want the lightest possible texture, use aquafaba. If you want a dense, fudgy brownie, use flax or chia seeds.

Start by replacing only the eggs and keeping everything else the same. If the result is too dry, add a tablespoon of extra liquid (milk, water, or oil) to the next batch. If it is too dense, try a different replacement or add baking soda and acid for lift. Most replacements work on the first try, but small adjustments often improve the result.

Frequently Asked Questions

Can I use oil or milk instead of eggs?

Oil adds moisture but does not bind ingredients, so it cannot replace eggs on its own. Milk is similar—it adds moisture but lacks binding power. You can use oil or milk as part of a combination (like applesauce plus a bit of extra oil), but they do not work as a single replacement.

What if I use the wrong replacement and the baked good turns out dense?

Dense texture usually means the replacement did not provide enough lift. Next time, add baking soda and acid to the recipe, or try aquafaba if the recipe allows it. If the baked good is also dry, add a tablespoon of extra liquid along with the leavening.

Do egg replacements work in all baking recipes?

Most work in cakes, cookies, muffins, and quick breads. Recipes that rely heavily on eggs for structure—like soufflés, custards, or meringues—are harder to adapt. Aquafaba works well in meringues, but custards and soufflés are better left to recipes written specifically without eggs.

Can I mix different replacements in one recipe?

Yes. In fact, combining replacements often gives better results than using one alone. For example, applesauce for moisture plus baking soda and acid for lift works well in many cakes. Start with one replacement and add another only if the first one does not give you the texture you want.

Does the replacement change the flavor of the baked good?

Applesauce and flax add subtle flavor. Banana adds noticeable sweetness and banana flavor. Aquafaba has a faint bean taste. Baking soda and acid, cornstarch, and chia seeds are mostly neutral. Choose based on whether the added flavor fits your recipe.
