1 Tbsp ground flax seeds + 3 Tbsp water = 1 egg

Depending on what you’re making, you might want to add a little baking powder for the leavener.

Also, have you thought about using a recipe that just doesn’t call for eggs? There are lots out there! Here’s one for dinner rolls:

Flat foods such as pancakes and cookies don’t rely on eggs for lift. In fact, in many cases, you can eliminate the egg without noticeably affecting the final product. That’s especially true if the recipe calls for only one egg. If you do omit the egg, however, it’s a good idea to add a tablespoon or two of additional liquid — soymilk, fruit juice, or water, for example — for each egg omitted to restore the recipe to its original moisture content.

When a recipe calls for three or more eggs — as many cakes do — the eggs perform a vital function and need to be replaced with an ingredient that can deliver a similar effect.

In recipes for baked goods that have a light, airy texture, replace eggs with an ingredient that provides lift. Any of the following ingredients can replace one whole egg in a recipe:

Half a small, ripe, mashed banana. This substitution gives the food a mild banana flavor, which can be nice in recipes for muffins, cookies, pancakes, and quick breads.

1/4 cup of any kind of tofu blended with the liquid ingredients in the recipe. Light or reduced-fat tofu cuts down on the fat and calories in the finished product.

1-1/2 teaspoons of a commercial vegetarian egg substitute, such as Ener-G Egg Replacer, mixed with 2 tablespoons of water. This product is a combination of vegetable starches and works wonderfully in virtually any recipe that calls for eggs. Natural foods stores sell it in 1-pound boxes.

1/4 cup of applesauce, canned pumpkin or squash, or pureed prunes. If you use these foods, know that, depending on the recipe, they may add a hint of flavor. If you want to give the food a lighter texture, add an extra 1/2 teaspoon of baking powder, because using fruit purees to replace eggs can make the finished product somewhat denser than the original recipe.

A heaping tablespoon of soy flour or bean flour mixed with a tablespoon of water. This mixture works similarly to vegetarian egg replacer.

2 tablespoons of cornstarch beaten with 2 tablespoons of water. This, too, works much like vegetarian egg replacer.

1 tablespoon of finely ground flaxseeds whipped with 1/4 cup of water. The flaxseeds gel and bind with the other ingredients.

2 tbsp corn starch = 1 egg
2 tbsp arrowroot flour = 1 egg
2 tbsp potato starch = 1 egg
1 heaping tbsp soy powder + 2 tbsp water = 1 egg
1 tbsp soy milk powder + 1 tbsp cornstarch + 2 tbsp water = 1 egg.
1 banana = 1 egg in cakes.
