Common egg replacements and what they do

Eggs bind ingredients together, add moisture, help things rise, and create structure in baked goods. No single replacement does all of these at once, so which one works depends on what you're making. A cookie needs different support than a cake, and a cake needs different support than a custard.

The most reliable replacements are applesauce, mashed banana, aquafaba (the liquid from canned chickpeas), flax eggs, chia eggs, and commercial egg replacers. Each one works best in certain recipes and fails in others. Knowing which to reach for saves you from a dense, gummy, or collapsed result.

Key Takeaways

  • Applesauce and mashed banana work well in moist cakes and quick breads but make cookies spread too much and won't help baked goods rise.
  • Aquafaba (chickpea liquid) whips into stiff peaks like egg whites and is the best choice for meringues, mousses, and angel food cakes.
  • Flax eggs and chia eggs bind and add moisture but work best in dense baked goods like brownies and won't create lift in layer cakes.
  • Commercial egg replacers like Bob's Red Mill are formulated to mimic eggs more closely and work across more recipe types than single-ingredient swaps.
  • Custards, scrambled eggs, and fried eggs have no reliable plant-based replacement and are better made with tofu or store-bought egg alternatives.

Applesauce and mashed banana for moisture and binding

Use unsweetened applesauce or mashed banana at a ratio of 1/4 cup per egg. Both add moisture and help ingredients stick together, which makes them good for brownies, quick breads, muffins, and dense cakes. They work because they contain pectin and fiber that hold water and bind the batter.

The downside is that they don't help baked goods rise, so cakes made with these replacements will be denser and flatter than the original. They also add their own flavor—banana is obvious, and applesauce can make a chocolate cake taste slightly fruity. Cookies made with these replacements spread too much and won't hold their shape well.

Applesauce is the safer choice if you want to hide the replacement. Unsweetened versions won't throw off your sugar balance. If you use sweetened applesauce, reduce the sugar in the recipe by 1/4 cup.

Aquafaba for whipping and lift

Aquafaba is the liquid inside a can of chickpeas. Three tablespoons of aquafaba replaces one egg. It's the only plant-based replacement that whips into stiff peaks like egg whites, which makes it the best choice for meringues, mousses, angel food cakes, and any recipe that needs air and structure.

Whip aquafaba with an electric mixer for 5 to 10 minutes until it forms peaks. It takes longer than egg whites and the peaks won't be quite as stable, but they will hold. Use it when ready after whipping—aquafaba foam collapses faster than egg foam.

Aquafaba doesn't work well in recipes that need eggs for binding and moisture, like brownies or cookies. It also has a faint bean flavor that some people notice in delicate cakes. Drain canned chickpeas over a bowl and save the liquid—don't buy it separately, as it's expensive that way.

Flax eggs and chia eggs for binding

Mix one tablespoon of ground flaxseed or chia seed with three tablespoons of water and let it sit for 15 minutes. This replaces one egg. The seeds absorb water and form a gel that binds ingredients and adds moisture, making these replacements good for brownies, cookies, and dense cakes.

Flax and chia eggs don't help baked goods rise, so they won't work in recipes that rely on eggs for lift. They also add a nutty or slightly earthy flavor that works in chocolate or spice cakes but can be noticeable in vanilla or lemon cakes. The texture of the seeds themselves can be gritty if you don't grind them finely.

These replacements are inexpensive and shelf-stable, so they're worth keeping on hand. Ground flaxseed and chia seed are sold in the baking aisle or bulk section of most grocery stores. Store them in the refrigerator after opening to keep the oils from going rancid.

Commercial egg replacers

Commercial egg replacers like Bob's Red Mill Egg Replacer, JUST Egg, or Orgran are formulated to mimic eggs across multiple functions. They usually contain starches, gums, and leavening agents that help with binding, moisture, and rise all at once. Follow the package instructions, as ratios vary by brand.

These products work in a wider range of recipes than single-ingredient swaps—they'll work in cookies, cakes, and quick breads without the same trade-offs. They're more expensive than applesauce or flax eggs, but they're more reliable if you bake often and want consistent results.

Some commercial replacers have a slight aftertaste or create a slightly different texture than eggs. Try a small batch first. Liquid replacers like JUST Egg are closer to whole eggs and work better in savory cooking, while powder replacers work better in baking.

What doesn't have a good replacement

Custards, scrambled eggs, fried eggs, and recipes where eggs are the main ingredient don't have reliable plant-based replacements. Aquafaba can't replicate the creamy, rich texture of a custard or scrambled eggs. Applesauce and flax eggs are too thick and won't cook the same way.

For these dishes, store-bought egg alternatives like JUST Egg or Orgran liquid replacers come closer, though they still won't taste identical. Silken tofu blended smooth can work in some custard recipes, but it requires adjusting the rest of the recipe. If you're making a dish where eggs are the star, a commercial alternative is your best bet.

How to choose the right replacement for your recipe

Start by asking what the eggs do in your recipe. If the recipe is a cake or brownie and eggs are there for moisture and binding, use applesauce, mashed banana, or a commercial replacer. If you're making a meringue or mousse and eggs are there for structure and air, use aquafaba. If you're making cookies or dense baked goods, flax or chia eggs work well.

Test one replacement at a time. Baking is sensitive to ratios, and switching multiple ingredients at once makes it hard to know what went wrong if the result isn't right. Keep notes on what worked and what didn't so you can repeat successes.

If a recipe fails, the most common reason is that the replacement didn't provide enough structure or rise. Add a teaspoon of baking powder to the next batch, or switch to a commercial replacer that includes leavening. If the result is too wet, reduce the liquid elsewhere in the recipe by a tablespoon or two.

Frequently Asked Questions

Can I use oil or milk instead of eggs?

Oil adds moisture but doesn't bind, and milk is mostly water. Neither one replaces what eggs do. Oil can make baked goods greasy, and milk alone won't hold the batter together. Use them alongside another replacement—for example, applesauce for binding plus a little extra oil for moisture—but not as a standalone swap.

Do I need to change the oven temperature when I use a replacement?

No. Bake at the temperature the recipe calls for. The replacement won't change how heat moves through the batter. What might change is the baking time—dense cakes made with applesauce may bake a few minutes faster because they're thicker, while aquafaba-based cakes may take a minute or two longer. Start checking for doneness a few minutes before the recipe says.

Why did my cake sink in the middle when I used a replacement?

The replacement probably didn't provide enough structure or rise. Applesauce, mashed banana, flax eggs, and chia eggs don't help cakes rise the way eggs do. Try a commercial replacer next time, or add a teaspoon of baking powder to give the batter more lift. Make sure you're not overmixing the batter, which can also cause sinking.

Can I use the same replacement in every recipe?

No. Each replacement works best in certain recipes. Aquafaba is great for meringues but won't work in brownies. Applesauce is good for moist cakes but makes cookies spread. Using the right replacement for the job gives you better results than trying to force one option into every recipe.

How do I know if a replacement is working?

The batter should look similar to the original recipe—not too thin or too thick. After baking, the result should be moist but not gummy, and it should hold together when you cut it. If it's dry and crumbly, the replacement didn't add enough moisture. If it's dense and heavy, it didn't provide enough lift. Adjust the next batch based on what you see.
