Egg Substitute Calculator

Find the best egg replacement for cookies, cakes, brownies, muffins, and meringues — scaled to your recipe.

Best substitutes for cookies (2 eggs)
  • Flax egg2 tablespoon ground flaxseed

    Binds well and adds a subtle nutty flavor; great for hearty bakes.

    Per egg: 1 tablespoon ground flaxseed + 3 tablespoons water, rested 5 minutes

  • Chia egg2 tablespoon chia seeds

    Gels into a strong binder; the seeds can stay visible in light batters.

    Per egg: 1 tablespoon chia seeds + 3 tablespoons water, rested 10 minutes

  • Commercial egg replacer2 egg's worth

    Powdered starch-and-leavening blend; reliable across most bakes.

    Per egg: Mix per the package directions for 1 egg

  • Egg substitutes work best in recipes calling for three eggs or fewer — beyond that, eggs do too much structural work to replace cleanly.
  • Let flax and chia eggs gel fully before adding them, so they bind like a real egg.

Tips & best practices

  • Match the substitute to the egg's job — binding, moisture, or structure — rather than picking one for everything.
  • Let flax and chia eggs gel fully before adding them so they bind like a real egg.
  • Use unsweetened applesauce so you do not accidentally add extra sweetness to the recipe.
  • Reach for aquafaba whenever a recipe needs whipped, airy structure like meringues or mousse.
  • Keep egg-free recipes to three eggs or fewer for the most reliable results.
  • Expect a slightly denser crumb — a small bump in baking powder can restore some lift.

Frequently asked questions

What is the best egg substitute for baking?
It depends on the bake. Flax and chia eggs bind well in cookies, muffins, and quick breads; applesauce and yogurt add moisture to cakes; and aquafaba whips up for meringues. The right choice matches what the egg was doing in the recipe.
How do I make a flax egg?
Mix 1 tablespoon of ground flaxseed with 3 tablespoons of water and let it sit for about 5 minutes until it thickens to a gel. That gel replaces one large egg and works best in hearty bakes like cookies and muffins.
How do I make a chia egg?
Stir 1 tablespoon of chia seeds into 3 tablespoons of water and let it rest for about 10 minutes until it forms a gel. It replaces one large egg and binds strongly, though the seeds can stay visible in light-colored batters.
Can I use applesauce instead of eggs?
Yes. Use 1/4 cup of unsweetened applesauce per egg. It adds moisture and tenderness, which makes it a good fit for cakes and muffins, though it does not provide much binding structure.
What is aquafaba and how does it replace eggs?
Aquafaba is the liquid from a can of chickpeas. Three tablespoons replace one whole egg, and because it whips into a foam much like egg whites, it is the go-to substitute for meringues and recipes that need airy structure.
How many eggs can I replace in a recipe?
Substitutes work most reliably in recipes calling for three eggs or fewer. Beyond that, eggs are doing so much structural and leavening work that replacements struggle to hold the bake together.
Will egg substitutes change the flavor or texture?
Sometimes. Mashed banana adds banana flavor, applesauce and yogurt add moisture and slight tang, and flax adds a mild nuttiness. Texture can be a little denser since substitutes rarely match an egg's lift exactly.
Do I need to adjust leavening when I skip eggs?
Eggs add some lift, so in recipes that relied on them you may want a little extra baking powder. A commercial egg replacer already includes leavening, which is one reason it works across many bakes.
