Egg Substitutes for Muffins, Cookies and Brownies
Want your number first? Open the free Baking Substitutions, or read on for how it works.

The three best egg substitutes for muffins, cookies and brownies are a flax egg (1 tablespoon ground flaxseed plus 3 tablespoons water, rested 5 minutes), 1/4 cup of unsweetened applesauce, and 3 tablespoons of aquafaba from a can of chickpeas. Each one replaces one large egg, and each one is right for a different bake.

Pick by what the egg was doing. Cookies and brownies need the egg to bind, so use flax or chia. Muffins usually just need the moisture, so applesauce or yogurt is enough. Anything that needed the egg for lift needs aquafaba, or baking soda plus vinegar.

Egg substitutes for muffins, cookies and brownies at a glance

Every row below replaces one large egg. Multiply for two, and read the last column before you multiply for three.

Substitute Amount per egg Best in What it does Watch out for
Flax egg 1 tbsp ground flaxseed + 3 tbsp water, rest 5 min Cookies, brownies, bran muffins Binds, adds a little moisture No lift at all. Faintly nutty
Chia egg 1 tbsp ground chia + 3 tbsp water, rest 10 min Cookies, brownies, dark muffins Stronger gel than flax Slightly gummier crumb. Grind the seeds first
Aquafaba 3 tbsp Muffins, light cookies, blondies Binds and genuinely leavens when whipped Less stable than egg white. Do not hold it for hours
Unsweetened applesauce 1/4 cup Muffins, cakey brownies Moisture only Does not bind. Cut the sugar back a little
Mashed ripe banana 1/4 cup Muffins, oat cookies Binds and moistens Tastes of banana. There is no hiding it
Silken tofu, blended 1/4 cup Fudgy brownies Binds, moistens, adds body Makes light bakes leaden
Plain yogurt or buttermilk 1/4 cup Muffins, soft cookies Tender, moist crumb, gentle tang Contains dairy. Does not aerate
Baking soda + vinegar 1 tsp soda + 1 tbsp vinegar Muffins, cupcakes Pure lift No binding, no moisture, no richness
Pumpkin puree 1/4 cup Spiced muffins, blondies Moisture and some binding Turns the batter orange
Commercial egg replacer Packet portion per egg All three Predictable, neutral, mostly starch and leavening Check the packet for wheat

Print that table and stick it inside a cupboard door. It is the whole article in one screen, and the rest of this page is the reasoning behind it.

First, work out what the egg was for

An egg does four separate jobs, and no substitute does all four. Get this part right and the swap almost picks itself.

The egg's job How you spot it What replaces it
Binding 1 to 2 eggs in a mixture that would otherwise crumble: cookies, brownies, bars Gels. Flax, chia, aquafaba
Moisture 1 egg in a muffin or quick bread that already has baking powder Purees. Applesauce, banana, pumpkin, yogurt
Leavening Eggs beaten before folding, or 3 or more eggs and little other leavener Whipped aquafaba, or soda plus acid
Richness Custards, curds, enriched doughs, anything where the egg is the point Nothing, honestly

Most home baking sits in the first two rows, which is why egg-free muffins, cookies and brownies work so well. The failures cluster in rows three and four: angel food, chiffon, meringue, curd, custard. Those are built out of egg protein rather than flavored with it, and no plant swap carries them.

Our longer piece on what eggs actually do in baking breaks the four jobs down further if you want the science.

Egg substitutes for muffins

Muffins are the easiest of the three, because a muffin recipe almost always contains baking powder or soda already. The egg is not holding the muffin up. It is adding moisture, a bit of structure and a little richness.

Best all round: 1/4 cup of unsweetened applesauce. It keeps the crumb damp for days. It also adds a mild apple sweetness, so pull back the sugar by a tablespoon or two per egg replaced.

Best for a light, high muffin: 3 tablespoons of aquafaba. This is the only swap that adds any lift on its own, so it is the right choice for a plain vanilla or blueberry muffin where you want the dome.

Best for a tender crumb: 1/4 cup of plain full fat yogurt. The acid reacts with baking soda, so you get a small bonus rise, and the fat gives a softer bite than applesauce does.

Best for bran, oat and whole wheat muffins: a flax egg. These batters are already dense and nutty, so flax disappears completely, and the gel helps hold together a crumb that heavy bran tends to shred.

One warning specific to muffins. Applesauce and banana both weigh the batter down. If your muffins already come out heavy, that swap will make it worse, and our guide to dry muffins covers the mixing habits that usually cause it.

Worked example: a 12-muffin recipe with one egg

Take a standard batter: 2 cups of all-purpose flour (250 g on the scale, since a cup is 125 g), 1/2 cup of sugar (100 g), 2 teaspoons of baking powder, 1 cup of milk, 1/3 cup of oil, 1 egg.

Replace the egg with 1/4 cup of unsweetened applesauce. Then make two small adjustments:

  1. Drop the sugar to 6 tablespoons (about 75 g), because the applesauce brings sweetness.
  2. Cut the milk by 2 tablespoons, because you have added a quarter cup of wet ingredient where there was 50 g of egg before.

Bake at the recipe's own temperature. The muffins come out slightly denser, noticeably moister, and they keep an extra day. Nobody at the table works out that there was no egg in them.

Egg substitutes for cookies

Cookies are where binding matters most. One egg in a batch of drop cookies is doing real structural work, holding a very high fat, very high sugar dough together while it spreads and sets.

Best all round: a flax egg. It gels firmly, it browns well, and its faint nuttiness is invisible in chocolate, oats, brown sugar or spice. Rest it a full 5 minutes until it thickens visibly before you add it, because unrested flax is just gritty water.

Best for pale, delicate cookies: 3 tablespoons of aquafaba. Sugar cookies, shortbread style rounds and anything vanilla stay pale and clean with aquafaba, where flax would leave visible brown specks.

Best for chewy oatmeal cookies: 1/4 cup of mashed banana or a chia egg. Both add chew. Banana brings flavor you will taste, so only use it where that fits.

Here is the spreading issue nobody warns you about. Flax and chia eggs hold a dough together more tightly than a real egg does, so cookies made with them spread less. If your cookies come out domed and cakey instead of thin and chewy, that is the cause. Fix it by flattening the dough balls before baking, or by adding a tablespoon of extra liquid per flax egg. Our page on cookies that will not spread covers the other causes if flattening does not do it.

Egg substitutes for brownies

Brownies are the most forgiving of the three, because a good brownie is already dense, wet and fudgy. You are not trying to protect a light crumb.

Best for fudgy brownies: 1/4 cup of blended silken tofu per egg. Blend it completely smooth first or you get pale lumps through the finished pan. Tofu is heavy and rich, which is exactly what a fudgy brownie wants.

Best for a middle-ground brownie: a flax egg. It binds without adding much weight and gives you a chewy edge and a set middle.

Best for cakey brownies: 1/4 cup of applesauce plus 1/4 teaspoon of baking powder. The applesauce brings moisture and the baking powder replaces the lift the egg was giving. Skip the baking powder if you want them fudgy, and read why brownies turn out cakey before you decide which side you are on.

Worked example: brownies with two eggs

A typical pan of brownies uses 1/2 cup of butter (113 g), 1 cup of sugar (200 g), 1/2 cup of cocoa powder (about 43 g, since a cup of cocoa is 85 g), 3/4 cup of flour (94 g) and 2 eggs.

Swap in 2 flax eggs: 2 tablespoons of ground flaxseed and 6 tablespoons of water, stirred and rested 5 minutes until it looks like loose jam. Add it where the eggs went, at the same point in the method.

What changes: the batter is thicker going into the pan, so spread it rather than pouring it. The bake runs a couple of minutes longer. The result is fudgier than the original and holds a cleaner cut edge once cooled.

What does not change: temperature, pan size, or the skewer test. Check an inch in from the edge and look for thick sticky crumbs rather than wet batter.

How many eggs can you actually replace?

This is the question that decides whether the bake works, and the honest answer is a small number.

Eggs in the recipe Realistic outcome
1 egg Any substitute in the table works. Almost no visible difference
2 eggs Works well. Pick a binder, expect slightly denser results
3 eggs Risky. Use aquafaba or a commercial replacer, not purees
4 or more Do not swap. Find a recipe designed without eggs

The reason is stacking. One quarter cup of applesauce per egg means a full cup of applesauce in a four-egg recipe, and a cup of extra wet puree turns any batter into pudding. Purees especially do not stack. Gels stack a little better, and whipped aquafaba stacks best of a bad set of options.

For a four-egg sponge, a genoise, a chiffon or a meringue, do not substitute. Those cakes are egg protein with some flour added, and the general egg substitute guide explains where the line sits. If it is only the whites you need, the vegan egg white substitutes page goes deeper on aquafaba technique.

Troubleshooting: what went wrong

Problem Likely cause Fix next time
Cookies domed and refused to spread Flax or chia bound the dough too tightly Flatten dough balls, or add 1 tbsp liquid per flax egg
Muffins dense and gummy Too much puree, or the batter got overmixed Use aquafaba instead, and stop mixing while lumps remain
Brownies would not set Applesauce with no binder Use flax, chia or tofu for the binding job
Everything tastes faintly of banana Banana in a bake that could not carry it Use applesauce or pumpkin instead
Cake sank in the middle Substitute could not carry the leavening job Add 1/4 tsp baking powder per egg replaced
Visible brown specks in a pale cookie Ground flaxseed Switch to aquafaba or a commercial replacer

Frequently asked questions

What is the best egg substitute for cookies?

A flax egg, made from 1 tablespoon of ground flaxseed and 3 tablespoons of water rested for 5 minutes. It binds the way an egg does and its mild nuttiness vanishes in chocolate, oats or brown sugar. For pale cookies where specks would show, use 3 tablespoons of aquafaba instead.

How much applesauce replaces one egg in muffins?

One quarter cup of unsweetened applesauce per large egg. It works best in a recipe that already contains baking powder or soda, since applesauce provides no lift at all. Cut the sugar by a tablespoon or so per egg, because applesauce is sweet on its own. The full applesauce egg substitute guide covers the sweetened versus unsweetened question.

Can you make brownies without eggs and still get a fudgy texture?

Yes, and brownies are the easiest of the three to make egg-free. Use 1/4 cup of blended silken tofu per egg for the fudgiest result, or a flax egg for something closer to the original. Skip applesauce unless you want cakey brownies, because it adds moisture without binding.

Does aquafaba really work as an egg substitute?

It does, and it is the only plant swap that makes a genuine foam. Use 3 tablespoons of the liquid from an unsalted can of chickpeas per whole egg. Whip it with a pinch of cream of tartar if the recipe beat the eggs. It is less stable than egg white, so it weeps sooner and will not carry a four-egg sponge.

Do I need to add baking powder when I use an egg substitute?

Only where the egg was providing lift. Flax, chia, applesauce, banana and tofu add none, so if the recipe was leaning on beaten eggs for rise, add 1/4 teaspoon of baking powder per egg replaced. Most muffin and cookie recipes already have enough leavening and need nothing extra.

Can I replace three or four eggs in one recipe?

Two is the comfortable limit. Three is possible with aquafaba or a commercial replacer, but purees at that level make the batter too wet and too heavy. At four eggs the recipe is built on egg protein, and you are better off finding a recipe written without eggs than patching one that was not.

Which egg substitute has no taste at all?

Aquafaba and a commercial egg replacer are the two truly neutral options. Chia is close behind, especially once ground, which makes it the better pick than flax in pale bakes. Banana is the strongest tasting of the group and pumpkin is not far behind, so save those for spiced or oaty recipes.
