If you need to replace an egg in baking, try these tested egg substitutes! I've done the experimenting for you, so you'll know what works best in cookies, brownies, and more.
To make an egg substitute, choose one of the options above per egg you plan on replacing. For example, if a muffin recipe calls for 2 eggs, you'll replace that with ½ cup of yogurt or mashed banana.
To make a flax egg, combine 1 tablespoon of ground flaxseed plus 2 to 3 tablespoons of water. (Use 2 tablespoons of water for a fluffy recipe, like muffins or cake.) Stir these together and let the mixture rest for 5 minutes.
When using an egg substitute in baked goods, you may need a slightly longer bake time. Cookies might need 2 more minutes, and cakes or muffins might need 5 more minutes. Let baked goods cool completely before enjoying them.
