Aquafaba – the seemingly magical liquid leftover from cooking chickpeas – has revolutionized vegan baking. For years, eggs were considered irreplaceable in many recipes, providing structure, leavening, and moisture. But aquafaba has stepped onto the scene as a powerful and versatile egg substitute, opening up a world of possibilities for plant-based bakers and those with egg allergies. But can you really use aquafaba in baking? The answer is a resounding yes! Let’s dive into the world of aquafaba baking and discover its secrets.
What Exactly Is Aquafaba?
Aquafaba, quite simply, is the water that chickpeas have been cooked in. This liquid, once discarded, is now a prized ingredient. During the cooking process, starches and proteins leach from the chickpeas into the water. This creates a solution with unique properties, particularly its ability to whip into a meringue-like foam. This foaming ability is the key to aquafaba’s success in baking.
The consistency of aquafaba can vary depending on the brand of chickpeas, the cooking time, and even the variety of chickpeas used. Some aquafaba will be thin and watery, while others will be thicker, almost like egg whites. The thicker the aquafaba, the better it will whip.
Where does aquafaba come from? It’s easily obtained by draining a can of chickpeas. You can also make your own aquafaba by cooking dried chickpeas and reserving the cooking liquid.
The Science Behind Aquafaba’s Baking Prowess
Understanding why aquafaba works in baking involves looking at its composition. The proteins and starches present in aquafaba mimic the properties of egg whites. When whipped, these proteins unfold and create a network that traps air, forming a stable foam. This foam provides leavening and structure to baked goods.
The starches contribute to binding and moisture retention, preventing baked goods from becoming dry or crumbly. The concentration of these proteins and starches is crucial for achieving the desired results.
This process is similar to what happens when you whip egg whites. The proteins in egg whites denature and create a similar network, trapping air and giving volume to meringues, cakes, and other baked goods.
How to Use Aquafaba as an Egg Replacement
Using aquafaba as an egg replacement requires a little understanding of substitution ratios. Generally, 3 tablespoons of aquafaba can replace one whole egg, and 2 tablespoons can replace one egg white.
However, these are just guidelines. The best approach is to start with the recommended ratios and adjust as needed based on the recipe and the consistency of your aquafaba.
Before using aquafaba, it’s often recommended to reduce it slightly. Simmering it on the stovetop until it reduces by about a third can concentrate the proteins and starches, making it even more effective as an egg replacer. Be sure to let it cool completely before using it.
When whipping aquafaba, use a clean, dry bowl and whisk. Start on low speed and gradually increase to high speed. It will take several minutes for the aquafaba to form stiff peaks, similar to egg whites.
Baking Applications: Where Aquafaba Shines
Aquafaba isn’t a one-size-fits-all egg replacement. It excels in certain baking applications more than others.
Meringues and Macarons
Aquafaba has gained immense popularity for its ability to create perfect meringues and macarons. Its foaming properties are almost identical to egg whites, resulting in light, airy, and stable structures. Vegan meringues and macarons made with aquafaba are virtually indistinguishable from their traditional counterparts.
The key to successful aquafaba meringues is to whip the aquafaba with cream of tartar or lemon juice to stabilize the foam. Adding sugar gradually while whipping will create a glossy and stiff meringue.
Cakes and Cupcakes
Aquafaba can be used to add moisture and lightness to cakes and cupcakes. It works best in recipes that don’t rely heavily on eggs for structure. For example, it’s excellent in recipes for chocolate cake, vanilla cake, and cupcakes.
When using aquafaba in cakes, be careful not to overmix the batter, as this can deflate the foam and result in a dense cake.
Cookies and Brownies
Aquafaba can also be used in cookies and brownies, adding a chewy texture and moisture. It works particularly well in recipes for chocolate chip cookies, oatmeal cookies, and fudgy brownies.
In cookies, aquafaba can help to bind the ingredients together and create a soft, chewy texture. In brownies, it contributes to a fudgy, moist consistency.
Other Baking Applications
Beyond meringues, cakes, cookies, and brownies, aquafaba can also be used in other baking applications, such as waffles, pancakes, and quick breads. It can even be used as a binder in veggie burgers or as a base for vegan mayonnaise.

What exactly is aquafaba, and where does it come from?
Aquafaba is the viscous liquid left over after cooking legumes, most commonly chickpeas. This starchy water contains plant proteins and carbohydrates that give it unique properties, making it an exceptional egg replacement in vegan baking and cooking. It’s important to note that the liquid from canned chickpeas is just as effective as homemade aquafaba, provided it doesn’t contain any added salt or other ingredients.
The magic of aquafaba lies in its ability to mimic egg whites due to its similar protein composition. These proteins denature when whipped, forming stable foams, similar to meringue. It provides structure and moisture to baked goods, binding ingredients together and contributing to a desirable texture.
Why is aquafaba a good substitute for eggs in baking?
Aquafaba’s unique composition allows it to replicate many of the functions that eggs perform in baking. It acts as a binder, holding ingredients together; a leavening agent, creating air pockets for a light and airy texture; and an emulsifier, helping to combine fats and liquids smoothly. This versatility makes it a remarkable egg replacer for various recipes.
Moreover, aquafaba is vegan and gluten-free, expanding baking possibilities for those with dietary restrictions or preferences. It’s a cost-effective and readily available ingredient, especially if you frequently cook chickpeas, reducing food waste by repurposing the liquid that would otherwise be discarded.
How do I prepare aquafaba for baking? Do I need to whip it?
For most baking applications, aquafaba doesn’t necessarily need to be whipped, but it often improves the final product. In recipes where eggs act as a binder or emulsifier, simply adding the aquafaba as a liquid substitute is sufficient. However, for recipes requiring airy textures like meringues or macarons, whipping aquafaba is essential.
To whip aquafaba, use an electric mixer and whip until stiff peaks form, similar to egg whites. This process typically takes 5-10 minutes. Adding a stabilizer such as cream of tartar or lemon juice can help create a more stable and long-lasting foam. The resulting whipped aquafaba can then be folded into your batter or used as a meringue topping.
What’s the typical substitution ratio of aquafaba for eggs in recipes?
Generally, 3 tablespoons (45 ml) of aquafaba can replace one whole egg in a recipe. For egg whites, 2 tablespoons (30 ml) of aquafaba are equivalent to one egg white. When replacing egg yolks, use 3 tablespoons (45 ml) of aquafaba for each yolk. These are good starting points, but some recipes might require slight adjustments depending on the other ingredients and desired outcome.
Experimentation is key when adapting recipes to use aquafaba. Start with the recommended substitution ratios and observe the consistency of your batter or dough. You may need to add a bit more flour or liquid to achieve the desired texture. It’s also wise to consult vegan baking resources or aquafaba-specific recipes for tried-and-true formulas.
What types of recipes work best with aquafaba?
Aquafaba shines in a wide range of recipes, especially those where eggs contribute primarily to binding and moisture. Cakes, muffins, cookies, and brownies are excellent candidates for aquafaba substitution. It also works well in pancakes, waffles, and quick breads.
Beyond baking, aquafaba can be used to create vegan versions of mayonnaise, mousse, and even cocktails. Its versatility makes it a valuable ingredient in any vegan or plant-based kitchen. The most spectacular, perhaps, is its ability to create perfect meringue.
Are there any downsides to using aquafaba?
One potential downside is that aquafaba can sometimes impart a slight “beany” flavor to baked goods, especially if used in large quantities. This can be mitigated by using a good-quality aquafaba (either homemade or from canned chickpeas with no added salt or flavorings), or by adding flavorful ingredients like vanilla extract or citrus zest to mask any subtle aftertaste.
Another consideration is that aquafaba doesn’t provide the same nutritional value as eggs. Eggs are a good source of protein and essential nutrients, which aquafaba lacks. Therefore, if you are relying on eggs for specific nutritional needs, you’ll need to find alternative sources in your diet.
Can I freeze aquafaba for later use?
Yes, aquafaba freezes exceptionally well, making it a convenient ingredient to have on hand. Simply pour the aquafaba into ice cube trays or small containers and freeze until solid. Once frozen, transfer the cubes or portions to a freezer bag for longer storage.
When you’re ready to use it, thaw the aquafaba in the refrigerator or at room temperature. The consistency might change slightly after thawing, but it will still whip up beautifully. Frozen and thawed aquafaba can be used in the same way as fresh aquafaba in all your favorite recipes.
