You're halfway through mixing cookie dough when you realize: no eggs. We've all been there. The good news? Plenty of everyday ingredients can step in for eggs and still give you a cookie worth eating.
Eggs do two things in cookies. They bind the dough together and add moisture. Some egg substitutes handle both jobs well. Others lean more toward one or the other. The trick is matching the right substitute to the kind of cookie you're making.
Here's a quick overview before we get into the details.
| Substitute | Ratio (= 1 Egg) | Texture Result | Best For |
|---|---|---|---|
| Flax Egg | 1 Tbsp ground flax + 3 Tbsp water | Chewy, slightly dense | Chocolate chip, oatmeal |
| Chia Egg | 1 Tbsp chia seeds + 3 Tbsp water | Chewy, holds shape well | Drop cookies, oatmeal raisin |
| Applesauce | 1/4 cup unsweetened | Soft, cake-like | Spice cookies, snickerdoodles |
| Mashed Banana | 1/4 cup mashed | Soft, moist | Peanut butter, oatmeal |
| Commercial Egg Replacer | Per package directions | Closest to eggs | Any cookie recipe |
| Aquafaba | 3 Tbsp chickpea liquid | Light, crispy edges | Meringues, thin & crispy cookies |
| Yogurt | 1/4 cup plain yogurt | Tender, slightly tangy | Sugar cookies, shortbread-style |
| Silken Tofu | 1/4 cup blended smooth | Dense, fudgy | Brownies, fudge cookies |
Now let's break each one down so you know exactly what to expect.
Ratio: 1 tablespoon ground flaxseed + 3 tablespoons water. Stir and let it sit for 5 minutes until it turns gel-like.
This is the go-to egg substitute for most bakers, and for good reason. Flax eggs bind dough beautifully and produce a satisfying chew. The flavor is extremely mild — you won't taste it in a finished cookie.
Flax eggs work best in chocolate chip cookies, oatmeal cookies, and anything where a slightly chewy center is a plus. They don't whip or add lift, so skip them for light, airy cookies.
Flavor notes: Neutral. Very faint nuttiness if you're really looking for it.
Ratio: 1 tablespoon chia seeds + 3 tablespoons water. Stir and wait 5 minutes.
Chia eggs work almost identically to flax eggs. The main difference? You'll see tiny dark specks throughout your dough. In darker cookies like chocolate or gingerbread, that's invisible. In pale sugar cookies, it's noticeable.
Chia eggs hold their shape a bit better during baking, which makes them a solid pick for drop cookies that you want to stay thick and round on the sheet.
Flavor notes: Completely neutral. No detectable taste.
Ratio: 1/4 cup (65g) unsweetened applesauce per egg.
Applesauce adds moisture and a gentle sweetness. Your cookies will come out softer and puffier — more cake-like than chewy. That's a feature, not a bug, especially in spice cookies and snickerdoodles where a tender crumb is exactly what you want.
You can reduce the sugar in your recipe by 1-2 tablespoons when using applesauce, since it brings its own sweetness to the party. Always use unsweetened — the sweetened kind throws off the balance.
Flavor notes: Light apple sweetness. Barely noticeable in spiced or chocolate cookies.
Ratio: 1/4 cup mashed ripe banana (about half a medium banana) per egg.
Let's be honest: banana adds banana flavor. That's not subtle, and it's not hiding. But in the right cookies, it's a bonus. Peanut butter cookies with mashed banana? Outstanding. Oatmeal cookies with banana and chocolate chips? Even better.
Use the ripest banana you have — the ones with brown spots. They mash smoothly and taste sweeter, which means better cookies.
Flavor notes: Distinct banana flavor. Plan your recipe around it.
Ratio: Follow package directions (typically 1.5 teaspoons powder + 2-3 tablespoons water per egg).
Brands like Bob's Red Mill, JUST Egg, and Ener-G are specifically designed to mimic eggs in baking. They're the closest thing to a true drop-in replacement. If you want your eggless cookies to taste and feel like the original recipe, a commercial replacer is your safest bet.
These work well in virtually every cookie type. Keep a box in your pantry and you'll never be stuck without an option.
Flavor notes: Neutral by design. No flavor impact.
Ratio: 3 tablespoons of chickpea liquid (from the can) per whole egg. For egg whites only, use 2 tablespoons and whip to stiff peaks.
Aquafaba is the dark horse of egg substitutes. It's just the liquid from canned chickpeas, but it whips, foams, and binds like nothing else on this list. It's the only substitute here that can replace egg whites in meringue-based cookies and macarons.
For regular cookies, unwhipped aquafaba adds moisture and helps with spread, giving you thinner cookies with crispy edges and chewy centers.
Flavor notes: None. Despite coming from chickpeas, it tastes completely neutral once baked.
Ratio: 1/4 cup plain yogurt (dairy or non-dairy) per egg.
Yogurt brings moisture and a slight tang that works really well in sugar cookies and butter-forward recipes. The acidity also reacts with baking soda, giving your cookies a little extra lift.
Use plain, unsweetened yogurt — Greek or regular both work. Greek yogurt is thicker, so your dough will be a bit stiffer, which is helpful if your recipe tends to spread too much.
Flavor notes: Very mild tanginess. Complements vanilla and lemon flavors nicely.
Ratio: 1/4 cup silken tofu, blended until completely smooth, per egg.
Silken tofu creates dense, fudgy cookies. Think brownie-style chocolate cookies or thick peanut butter cookies that are almost truffle-like in the middle. It adds protein and structure without any detectable tofu flavor.
The key is blending it smooth. Chunks of tofu in your cookie dough won't do you any favors. A quick blitz in a blender or food processor is all it takes.
Flavor notes: Neutral when blended smooth. Completely undetectable in chocolate cookies.
A few things to keep in mind no matter which substitute you pick:
Start with one egg. If your recipe calls for two or more eggs, try replacing just one with a substitute and use a real egg for the rest (if you have one). This gives you a safety net while you learn how the substitute behaves.
Chill your dough. Egg-free cookie dough tends to be stickier. Thirty minutes in the fridge firms it up and makes it easier to scoop and shape.
Don't overmix. Without eggs providing structure, overmixed dough can turn out tough. Mix until just combined and stop.
Expect slight differences. Egg-free cookies won't be identical to the original. They'll be close — sometimes even better — but the texture will shift. That's normal, and it's part of the fun of figuring out what works for your kitchen.

Keep baking:
A flax egg (1 tablespoon ground flaxseed + 3 tablespoons water, rested 5 minutes) works best for chocolate chip cookies. It provides enough binding without changing the flavor, and you get a slightly chewier texture that pairs perfectly with melted chocolate.
Yes. Use 1/4 cup (about 65g) unsweetened applesauce per egg. Applesauce adds moisture and a touch of sweetness, making it ideal for oatmeal cookies, spice cookies, and snickerdoodles. Your cookies will be softer and more cake-like than with eggs.
Use 1/4 cup mashed ripe banana (about half a medium banana) to replace one egg. Banana works as both a binder and a moisture source. It adds a noticeable banana flavor, so it works best in cookies where that taste is welcome — like oatmeal raisin, peanut butter, or chocolate cookies.
Aquafaba is the liquid from a can of chickpeas. Use 3 tablespoons of aquafaba to replace one whole egg, or whip 2 tablespoons to stiff peaks to replace one egg white. It's flavor-neutral and works especially well in meringue-based cookies, macarons, and thin crispy cookies.
Yes, each substitute affects texture differently. Flax and chia eggs make cookies chewier. Applesauce and banana make them softer and more cake-like. Aquafaba produces lighter, crispier cookies. Yogurt adds moisture and tenderness. Choosing the right substitute depends on the cookie style you want.
