The best egg replacements depend on what the eggs do in your recipe
Eggs serve different purposes in baking: they bind ingredients together, add moisture, create lift, or enrich flavor. The replacement you choose depends on which job the eggs are doing in your specific recipe. A cookie that needs structure requires a different substitute than a cake that needs rise, and a dense brownie needs something different from both.
The most reliable replacements are applesauce, mashed banana, aquafaba (the liquid from canned chickpeas), flax eggs, and commercial egg replacers. Each works best in certain situations. Knowing which to reach for saves you from dense, gummy, or flat results.
Key Takeaways
- Applesauce and mashed banana work well in moist cakes and brownies but can make cookies too soft unless you reduce other liquids in the recipe.
- Aquafaba (chickpea liquid) whips into stiff peaks like egg whites and is the best choice for meringues, angel food cake, and recipes that need airy structure.
- Flax eggs (ground flaxseed mixed with water) bind well in dense baked goods like muffins and quick breads but add a noticeable nutty flavor.
- Commercial egg replacers like Bob's Red Mill work across most recipes but perform best in cookies and cakes rather than recipes that depend on eggs for rise alone.
- The amount of liquid in your batter matters: applesauce and banana add moisture, so you may need to reduce other wet ingredients to avoid a soggy result.
Applesauce and mashed banana for moisture-based baking
Use unsweetened applesauce or mashed banana when you need eggs to add moisture and bind ingredients. These work best in brownies, chocolate cakes, spice cakes, and muffins—recipes where the crumb is already dense and forgiving. Replace one egg with one-quarter cup of applesauce or mashed banana.
The trade-off is texture. Applesauce and banana add liquid, so your batter becomes wetter. If your recipe calls for three eggs and you use three-quarter cup of applesauce, the result will be softer and more cake-like than the original. This is fine for brownies and muffins. For cookies, reduce the other liquids (milk, oil, or water) by two to three tablespoons per egg replaced, or your cookies will spread too much and bake unevenly.
Mashed banana adds sweetness and flavor, which works in chocolate, spice, and fruit cakes but can overpower delicate flavors like vanilla or lemon. Applesauce is more neutral and works in almost any recipe. Both brown slightly during baking, so they won't lighten the color of a white or yellow cake the way whole eggs would.
Aquafaba for recipes that need rise and structure
Aquafaba is the liquid left in a can of chickpeas (or other legumes). It behaves remarkably like egg white: it whips into stiff peaks, stabilizes foam, and creates lift. Use it when you need eggs to do the heavy lifting—in angel food cake, meringues, mousses, or any recipe where the eggs are whipped separately and folded in.
Replace one egg white with three tablespoons of aquafaba. For whole eggs in recipes that don't require whipping, use three tablespoons of aquafaba plus one tablespoon of cornstarch or tapioca starch per egg. The starch helps bind and adds structure that aquafaba alone cannot provide.
Aquafaba has almost no flavor and no color, so it won't change the taste or appearance of your baked good. The main limitation is that it works best in recipes where structure comes from air (whipped foam) rather than from chemical leavening alone. A straightforward vanilla cake leavened only by baking soda may be denser than the original, but a chiffon cake or angel food cake will be nearly identical.
Flax eggs for binding in dense baked goods
A flax egg is one tablespoon of ground flaxseed mixed with three tablespoons of water, left to sit for five minutes until it thickens. Use it in muffins, quick breads, cookies, and brownies where you need binding and structure but not necessarily lift. Replace one egg with one flax egg.
Flax eggs work because the ground seeds release a gel-like substance that holds ingredients together. They add a subtle nutty flavor, which is pleasant in chocolate, spice, and whole-grain baked goods but noticeable in vanilla or lemon recipes. They also darken the crumb slightly.
Flax eggs absorb moisture, so your batter may be thicker than the original recipe. If the batter looks too dry, add a tablespoon of water or milk. Flax eggs work less well in recipes that depend on eggs for rise alone—a sponge cake or soufflé will be denser and flatter than intended.
Commercial egg replacers for all-purpose baking
Products like Bob's Red Mill Egg Replacer, Ener-G, and store-brand equivalents are powders made from starches and leavening agents. They work across most recipes and are the most predictable option if you bake frequently without eggs. Follow the package directions, which typically call for mixing the powder with water to create a slurry before adding to your batter.
Most commercial replacers use a ratio of one and one-half teaspoons of powder plus two tablespoons of water per egg. They perform well in cookies, cakes, and quick breads. They are less reliable in recipes where eggs are the primary source of structure—angel food cake or a custard-based filling will not work as well.
The advantage of commercial replacers is consistency: the formula is the same every time, so your results are more predictable than with applesauce or banana. The disadvantage is cost and the fact that they contain additives. If you bake only occasionally, a single can lasts a long time, but if you bake weekly, you may find applesauce or aquafaba more economical.
Silken tofu for rich, moist cakes
Silken tofu (not firm tofu) blended smooth works in rich, moist cakes and brownies. Use one-quarter cup of blended silken tofu per egg. It adds moisture and creates a tender crumb without adding flavor or sweetness.
Silken tofu works best in chocolate cakes, brownies, and recipes with strong flavors that mask any subtle soy taste. It does not work well in cookies or recipes where you need structure from whipping. The texture is very smooth, so your batter will be thinner than with applesauce or banana, and you may need to add a tablespoon of flour or cornstarch to compensate.
Oil and water for straightforward, sturdy baked goods
In a pinch, you can replace one egg with three tablespoons of water or milk mixed with one tablespoon of neutral oil (vegetable, canola, or coconut). This works in brownies, dense cakes, and muffins where the recipe already has enough structure from flour and leavening.
This method adds moisture and fat but no binding power, so it works only in recipes that are already sturdy. It will not work in cookies, sponge cakes, or anything that depends on eggs for structure. The result will be slightly less rich and tender than the original, but still acceptable in chocolate or spice cakes.
How to choose the right replacement for your recipe
Start by asking what the eggs do in your recipe. If the recipe calls for whipping eggs or egg whites separately, use aquafaba. If the recipe is a moist cake or brownie, use applesauce, banana, or silken tofu. If you need a reliable all-purpose option, use a commercial egg replacer or flax eggs. If you are baking something sturdy like a muffin or quick bread, any of these will work, so choose based on flavor and what you have on hand.
Test one recipe at a time and take notes on what works. A replacement that is perfect for chocolate cake may not work for sugar cookies, and a replacement that works in one brand's recipe may not work in another's because the ratios of dry to wet ingredients vary. Once you find a replacement that works for a particular type of recipe, you can use it again with confidence.
Frequently Asked Questions
Can I use mayonnaise as an egg replacement?
Yes, in small amounts. Mayonnaise is mostly oil and eggs, so it adds fat and binding. Use three tablespoons of mayonnaise per egg in brownies and dense cakes. It works less well in cookies or recipes where you need lift. The flavor is neutral enough that it won't change the taste of chocolate or spice cakes.
What if my recipe calls for eggs but doesn't say how many?
Look at the ingredient list and count them. If the recipe is vague (like "eggs as needed"), it is usually an older recipe or one that was not tested with precision. Start with the assumption that the recipe calls for one egg per cup of flour, then adjust based on how the batter looks. If it seems too dry, add liquid; if too wet, add flour.
Do I need to change baking time or temperature when I use a replacement?
Usually not. Most egg replacements bake at the same temperature and time as the original recipe. The main difference is texture: replacements may produce a slightly denser or softer crumb, but the baking time stays the same. If your baked good is browning too fast on top, lower the oven temperature by 25 degrees and bake a few minutes longer.
Why did my cookies spread too much when I used applesauce?
Applesauce adds moisture, which makes the dough softer and causes cookies to spread more during baking. Reduce the other liquids in the recipe by two to three tablespoons per egg replaced. You can also chill the dough for 30 minutes before baking, which helps cookies hold their shape.
Can I mix different egg replacements in the same recipe?
Yes, if the recipe calls for multiple eggs and they serve different purposes. For example, in a cake that calls for three eggs, you could use aquafaba for one (to add lift), applesauce for another (to add moisture), and a flax egg for the third (to bind). This is advanced baking and requires testing, but it can produce better results than using the same replacement for all three eggs.
