The best substitute for eggs depends on what the eggs are doing in your recipe. Eggs serve three main roles in cooking: binding ingredients together, helping baked goods rise, and adding moisture. No single substitute does all three equally well, but once you know which job the egg is performing, you can pick a replacement that handles it reliably.
Why Eggs Are Hard to Replace
Eggs are multitaskers. The whites contain proteins that trap air when whipped, which is how angel food cake and meringues get their lift. The yolks contribute fat and act as an emulsifier, helping oil and water-based ingredients blend smoothly. In something like a muffin or a cookie, eggs do a bit of everything: they bind the flour and sugar together, add moisture, and contribute to the rise. That’s why a substitute that works perfectly in brownies might fail in a soufflé. The trick is matching the substitute to the function you need most.
Best Substitutes for Binding
If you’re making cookies, muffins, pancakes, or quick breads where the egg mainly holds everything together, seed-based “eggs” are your strongest option.
Flax egg: Mix 1 tablespoon of ground flaxseed with 3 tablespoons of water and let it sit for a minute or two until it thickens into a gel. This replaces one egg. Flax eggs work well in heartier baked goods like oatmeal cookies, banana bread, and whole wheat muffins. They add a very slight nutty flavor and can darken the color of lighter batters.
Chia egg: The ratio is the same: 1 tablespoon of ground chia seeds to 3 tablespoons of water, but chia needs closer to 10 minutes to fully gel. It’s a bit more neutral in flavor than flax. Both seed eggs scale easily. For two eggs, use 2 tablespoons of seeds and 6 tablespoons of water.
Both options add fiber but very little protein compared to a real egg’s 6 to 7 grams. They won’t contribute any lift, so they’re not ideal for recipes that rely on eggs for rise.
Best Substitutes for Leavening
When a recipe needs eggs primarily for lift (think fluffy cakes and light cupcakes), you need something that creates gas or traps air.
Vinegar and baking soda: Mix 1 tablespoon of vinegar (white or apple cider) with 1 teaspoon of baking soda for each egg you’re replacing. The acid-base reaction produces carbon dioxide bubbles that help the batter rise and stay fluffy. Add this mixture last, right before baking, so you capture the bubbles before they escape. This works especially well in chocolate cake and vanilla cupcakes where the slight tang disappears during baking.
Aquafaba: The liquid from a can of chickpeas whips into stiff peaks just like egg whites. Use about 3 tablespoons of aquafaba per egg. It’s one of the few substitutes that can handle meringues, macarons, and mousses, recipes where whipped egg whites are the entire structural foundation. It adds no noticeable flavor.
Best Substitutes for Moisture
In dense, fudgy recipes like brownies, banana bread, or spice cake, the egg is mostly contributing moisture and richness. Fruit purees handle this well.
Applesauce: Use 1/4 cup of unsweetened applesauce per egg. It adds moisture and a touch of sweetness without a strong flavor. Baked goods made with applesauce tend to be slightly denser and more tender than those made with eggs.
Mashed banana: Also 1/4 cup per egg. Banana adds more noticeable flavor than applesauce, so it works best in recipes where that taste is welcome. Both fruit purees make baked goods a bit heavier, so they’re not the right choice for anything that needs to be light and airy.
Best Substitutes for Scrambles and Breakfast
If you’re looking to replace eggs on a plate rather than in a recipe, the options are different.
Tofu scramble: Drain a 12-ounce block of extra-firm silken tofu and add it to a hot, oiled skillet. Let it sit for 2 to 3 minutes to develop a light crust before breaking it into bite-sized pieces with a spatula. Go gently here. Overworking the tofu turns it crumbly instead of giving you satisfying chunks that mimic scrambled eggs. Season with nutritional yeast, turmeric for color, onion powder, and black pepper. For a more convincing egg flavor, add a pinch of kala namak (black salt), which has a sulfurous, eggy taste.
Liquid egg replacers: Products like Just Egg use mung bean protein as their base, combined with canola oil and turmeric for color. You shake the bottle, pour it into a pan, and cook it the same way you’d cook scrambled eggs. The texture is closer to real eggs than tofu, though the protein content and flavor profile are different from chicken eggs.

How Many Eggs You Can Replace
Most substitutes work reliably when a recipe calls for one or two eggs. Once you get to three or more, the eggs are doing serious structural work, and substitutes start to struggle. A recipe calling for nine egg whites, like angel food cake, is nearly impossible to replicate with flax or applesauce. In those cases, aquafaba is your best bet, though even it requires some trial and error at high volumes.
For recipes with three or more eggs, consider combining substitutes. A flax egg for binding plus the vinegar-baking soda combo for lift can cover more ground than either one alone. Start by replacing just one or two eggs with substitutes and keeping the rest as real eggs if your situation allows it. This lets you reduce eggs without risking a complete texture failure.
Matching Substitutes to Common Recipes
Brownies and dense cakes do well with applesauce or mashed banana, since they’re already meant to be rich and moist. Cookies hold together best with flax or chia eggs. Fluffy cakes and cupcakes need the vinegar-baking soda reaction or aquafaba. Pancakes and waffles are forgiving and work with almost any substitute, though mashed banana adds a nice flavor bonus. For anything that relies on whipped egg whites (meringue, macarons, pavlova), aquafaba is the only reliable plant-based option.
No substitute perfectly replicates everything an egg does. But in most everyday baking, you won’t notice a significant difference if you pick the right one for the job.
