Aquafaba can replace egg yolks in baking, where the yolk's main job is to bind ingredients and hold in moisture. It works in recipes like cookies, cakes, brownies, and quick breads. It does not add the fat and richness a yolk brings, so it is not a one-to-one swap in custards or curds that depend on the yolk itself.
This guide explains what an egg yolk actually does in a recipe, where aquafaba stands in for it, and where it falls short.

The Quick Answer
Yes, aquafaba can stand in for egg yolks in most baking. In a cookie or a cake, a yolk is mostly there to bind the ingredients together and keep the crumb moist. Aquafaba does both of those jobs well, which is why it works as an egg substitute across so many recipes.
The honest limit is richness. An egg yolk is high in fat, and that fat adds a specific texture and mouthfeel to custards, curds, and other yolk-heavy recipes. Aquafaba is made from chickpeas and water, so it has no fat to contribute. In bakes where the yolk's fat is doing the work, aquafaba is not a direct replacement.
The good news is that for everyday baking, binding and moisture are what you need, and that is exactly what aquafaba delivers.
What an Egg Yolk Does in Baking
Before you replace a yolk, it helps to know what it was doing. Egg yolks play three roles in a recipe:
- Binding: The proteins in a yolk help hold the other ingredients together so a batter or dough sets into one structure instead of crumbling apart.
- Moisture and tenderness: Yolks keep baked goods soft and stop them drying out, which is why they make cookies chewy and cakes tender.
- Fat and richness: Yolks are high in fat, which adds a smooth, rich mouthfeel. This matters most in custards, curds, and ice cream bases built around the yolk.
Aquafaba covers the first two of those roles. The third, the fat, is the one it cannot replicate, and knowing that difference is the key to using it well.
How Aquafaba Binds
The proteins and starches in aquafaba are what let it bind and hold structure.
Aquafaba is the liquid from cooked chickpeas, and it carries dissolved proteins and starches out of the beans and into the water. Those two things are what make it work like an egg.
When aquafaba goes into a batter and bakes, the proteins set with the heat and the starches hold on to moisture, so the ingredients lock together into a stable structure as they cook. That is the same job a yolk does when it binds a recipe, which is why aquafaba can take its place in so many bakes.
This is the "It Binds" half of what aquafaba can do. The other half is whipping, where the same proteins trap air to make foams and meringues. For that side, see our guide on making vegan egg whites with aquafaba.
Where It Works
Aquafaba stands in for eggs, yolks included, in recipes where binding and moisture are the yolk's main job:
- Chewy cookies: Aquafaba binds the dough and keeps the centers soft.
- Cakes: It holds the crumb together and keeps it tender.
- Brownies: It binds the batter for that dense, fudgy texture.
- Quick breads and muffins: It gives structure without drying things out.
- Pancakes and waffles: It binds the batter and helps with lift.
These are the everyday bakes where most people reach for eggs, and they are exactly where aquafaba earns its place.

Being straight about the limits is what makes the rest trustworthy. Aquafaba is not a direct yolk replacement in recipes built around the yolk's fat and richness:
- Custards and pastry cream: These rely on the fat in the yolk for their smooth, rich set. Aquafaba has no fat to give.
- Lemon curd and other curds: The richness and body come from yolks. Aquafaba will not reproduce that texture on its own.
- Ice cream bases: A classic custard base leans on yolk fat for creaminess.
If a recipe calls for yolks specifically and is all about that rich, silky texture, aquafaba is the wrong tool. For everything in the section above, it is the right one.
How to Use It
In most recipes you are replacing whole eggs, and the ratio is simple:
| You need | Use this much aquafaba |
|---|---|
| 1 whole egg | 3 tablespoons |
| 1 egg white | 2 tablespoons |
When a recipe calls for yolks only, the cleanest approach is to think in whole eggs. Use the whole-egg ratio to match the binding and moisture the recipe needs, and know that you are replacing what the yolk does structurally, not the fat it adds. If the recipe depends on the yolk's richness, that is the case where aquafaba will not carry it.
For a full breakdown of every ratio, see our aquafaba to egg conversion guide. If you are new to aquafaba entirely, start with what is aquafaba.
One more thing worth knowing: aquafaba comes as a liquid or a powder, and the liquid skips the mixing step. If you are deciding between them, see aquafaba powder vs liquid.
How to Store Aquafaba
You do not have to use a whole carton at once. Here is how to store Plant Whip liquid aquafaba:
| Form | Storage Method | Duration |
|---|---|---|
| Plant Whip (unopened) | Pantry, shelf-stable | Until best-by date |
| Plant Whip (opened) | Refrigerator | 7 days |
| Frozen cubes | Ice cube tray, then freezer bag | Up to 3 months |

Freezing instructions
Pour unwhipped Plant Whip into ice cube trays, filling each compartment about three-quarters full. Freeze until solid, then transfer the cubes to a resealable bag and label with the date.
Each cube is roughly 1 tablespoon. When a recipe calls for aquafaba, thaw the cubes at room temperature and use as usual.
Frequently Asked Questions
Can aquafaba replace egg yolks?
Yes, in most baking. An egg yolk mainly binds ingredients together and holds in moisture, and aquafaba does both. It does not add the fat and richness of a yolk, so it is not a direct swap in custards, curds, or other recipes built around the yolk itself.
How much aquafaba replaces an egg yolk?
There is no clean one-to-one ratio for yolks, because aquafaba replaces what the yolk does structurally rather than the yolk itself. In practice, most recipes are easiest to handle by replacing whole eggs at 3 tablespoons of aquafaba per egg.
Does aquafaba work as a binder in baking?
Yes. The proteins and starches in aquafaba set as they bake and hold moisture, which locks a batter or dough into a stable structure. That is the same binding role a yolk plays in cookies, cakes, and brownies.
When should you not use aquafaba instead of yolks?
Skip it when a recipe depends on the yolk's fat for its texture, such as custards, pastry cream, lemon curd, or a custard-style ice cream base. Aquafaba has no fat, so it will not reproduce that rich, silky result.
