Best Egg Substitutes for Baking (Complete Guide)
You are halfway through a cake batter, the oven is already warm, and the egg carton in your fridge is empty. I have lived this exact moment so many times that I stopped counting. That is why learning the best egg substitutes for baking became one of the most useful skills in my kitchen. Over the years I have baked soft cakes with yogurt, fudgy brownies with applesauce, and cookies held together with nothing but seeds and water. Some tests failed in funny ways. Most worked so well that nobody at my table could tell the difference.
This complete guide is my full notebook. Every swap below gives you the exact amount for one egg, what it bakes best, and my honest note from real testing. Where one swap needs a deeper guide of its own, like cookies or brownies, I linked my full post on it, so you can go as deep as you need.
What Does an Egg Do in Baking?
An egg in a batter does four jobs. It binds the mix so your bake holds together. It adds moisture so cakes stay soft. It helps the rise, so sponges and cupcakes come out light. And it adds richness and golden color.
No single swap does all four jobs at once, and that is fine. You just match the swap to the main job. In a dense brownie, binding and moisture matter most. In a light vanilla cake, lift matters most. The bakers at King Arthur share a guide to substituting eggs with test results very close to mine, and it is a good second source if you like to compare before you bake.
The 13 Swaps I Trust Most
1. Flax Egg — My Everyday Hero
Amount for 1 egg: 1 tablespoon ground flaxseed + 3 tablespoons water. Stir and rest 5 to 10 minutes until thick.
This is the swap I use most of all. It binds cookies, muffins, and quick breads with almost no change in taste, just a tiny nutty note. My first flax gel looked so odd that I nearly threw it away. Then it thickened, my muffins rose soft and golden, and I was sold for life. I keep ground flax in my freezer so it stays fresh. My full method, with the exact ratio and storage tips, is in my flax seed egg substitute guide.
I use Anthony’s organic flaxseed meal — it is ground fine, so the gel comes out smooth every time.
2. Chia Egg — The Strong Binder
Amount for 1 egg: 1 tablespoon chia seeds + 3 tablespoons water. Stir well and rest 10 minutes.
Chia builds a thicker gel than flax, so I pick it when a recipe needs real holding power. It is the binder I trust in my egg substitute for meatballs tests, where the mix sliced clean and stayed firm. In baking, it holds muffins and hearty quick breads together with no fuss. One honest note: the dark seeds can show in pale batters, so I save chia for chocolate and spiced recipes where nobody can see them.
Whole seeds gel better than ground here — I buy the BetterBody Foods organic bag, it lasts for months of baking.
3. Aquafaba — The Magic One
Amount for 1 egg: 3 tablespoons of liquid from a can of chickpeas. For 1 egg white, use 2 tablespoons.
The first time I whipped chickpea liquid into white peaks, I laughed out loud alone in my kitchen. Aquafaba foams like egg whites, so it is the only swap that makes real meringue, mousse, and soft sandwich cookies. It adds almost no taste once baked. My complete aquafaba as egg substitute guide covers whipping times, storage, and the recipes where it beat every other swap I tried.
4. Unsweetened Applesauce — The Moisture Maker
Amount for 1 egg: 1/4 cup unsweetened applesauce.
Applesauce keeps cakes and muffins soft for days. It gave the best moist crumb in my egg substitutes for brownies tests, where the squares came out dark, fudgy, and rich. Always use the unsweetened kind, or your bake may end up too sweet. If a recipe has more than 2 eggs, I add a small pinch of extra baking powder, because applesauce brings moisture but not much lift on its own.
5. Mashed Banana — Sweet and Simple
Amount for 1 egg: 1/4 cup ripe mashed banana, about half a medium banana.
Banana binds and adds moisture in one easy step, and kids love the taste. It is perfect for muffins, pancakes, and soft sweet breads. The rule is simple: your bake will taste a little like banana. In a chocolate muffin, that is a bonus. In a lemon cake, it fights the main flavor, so pick a different swap for citrus recipes. Use bananas with lots of brown spots. They mash smooth, taste sweetest, and mix in with no lumps.
6. Plain Yogurt — The Cake Saver
Amount for 1 egg: 1/4 cup plain yogurt.
Yogurt is my quiet hero for cakes. It adds moisture, a gentle tang, and a tender crumb that tastes like it came from a good bakery. Greek yogurt is thicker and richer, regular yogurt is lighter, and both work well. I once saved a birthday cake with yogurt after finding my eggs had gone bad an hour before guests arrived. The birthday girl asked me for the recipe. After that day, yogurt stopped being my backup plan and became a first choice.
7. Silken Tofu — The Invisible Swap
Amount for 1 egg: 1/4 cup silken tofu, blended fully smooth.
Tofu in a cake sounds strange until you taste the slice. Blended silken tofu disappears into dense cakes, brownies, and cheesecake-style bakes. It adds body with zero taste of its own, which makes it great when you want no hint of fruit or nuts in the final bake. The one key word is blended. Skip the blender and you get white lumps in your batter. I learned that once, in a very sad chocolate cake, and I never skipped it again.
8. Baking Soda and Vinegar — The Lift Team
Amount for 1 egg: 1 teaspoon baking soda + 1 tablespoon white vinegar or apple cider vinegar.
This pair does not bind. It lifts. The soda and vinegar fizz together and fill your batter with tiny bubbles, so light cakes and cupcakes rise soft and fluffy. Mix it in at the very end and get the pan into the oven right away, because the bubbles start working at once. You will not taste the vinegar in the baked cake at all. This is my top pick for white and vanilla cakes where a soft crumb matters most.
9. Pumpkin Purée — The Warm and Cozy One
Amount for 1 egg: 1/4 cup pumpkin purée.
Pumpkin works like applesauce and banana, but with its own warm color and soft, cozy taste. I use it in muffins, pancakes, and soft cookies, and in chocolate recipes all year, because cocoa hides the orange color fully. Always use plain purée, not pie filling, which already has sugar and spice mixed in. One can covers many bakes, and the rest freezes well in an ice cube tray for the next round.
10. Nut Butter — The Rich Binder
Amount for 1 egg: 3 tablespoons smooth peanut butter, almond butter, or any nut butter you like.
Nut butter binds with power and adds rich, healthy fats, so cookies and bars hold together and taste deep and toasty. It was one of the top scorers in my egg substitute for binding in baking tests. The nut flavor does show, so use it where nuts taste right: oat bars, peanut butter cookies, and brownies. Stir your jar well before you measure, because the oil on top can make a batter greasy.
11. Cornstarch Slurry — The Quiet Helper
Amount for 1 egg: 2 tablespoons cornstarch or arrowroot + 3 tablespoons water, mixed smooth.
In baking, this slurry helps bind light batters and keeps pie fillings and custard-style bakes smooth when eggs run out. It is also the same swap I use as an egg substitute for fried chicken coating, where it holds the breading on and fries up crisp and golden. It has no taste and no color, which makes it a safe pick for pale, delicate recipes where banana or pumpkin would change the whole look of the dish.
12. Mayonnaise — The Strange One That Works
Amount for 1 egg: 3 tablespoons mayonnaise.
Stay with me here. Mayo is mostly egg and oil, so in a batter it acts like both at the same time. It makes boxed mixes taste rich and homemade, which is why it is a key trick in my egg substitute for cake mix guide. You taste zero mayo in the finished cake. I tested it on my family without telling them first, and the plate came back empty, with two requests for a second slice.
13. Store-Bought Egg Replacer — The Easy Button
Amount for 1 egg: follow the box, usually one spoon of powder mixed with water.
Powder replacers are a simple mix of starches that bind well in most home baking. I keep a box in my pantry for busy days and for the cookie tests in my egg substitute for cookies post, where it gave the cleanest, most neutral result of all. It has no taste, no color, and a long shelf life. If you are new to egg-free baking, this is the least stressful place to start, and it is very kind to beginners.
The box I keep in my own pantry is Bob’s Red Mill — it has never failed my cakes.

A second chart of substitute amounts and best uses lines up closely with my own test results, if you want to compare before your first try.
How to Choose the Right Swap in 10 Seconds
Ask one question: what was the egg doing in this recipe? If it was holding things together, pick flax, chia, nut butter, or the replacer powder. If it was adding moisture, pick applesauce, banana, yogurt, pumpkin, or tofu. If it was making the bake rise, pick aquafaba or the soda and vinegar team. The best egg replacement is simply the one that matches the job of the egg in your recipe.
One more honest rule from my notebook: swaps work best in recipes with 1 to 3 eggs. If a cake asks for 5 or 6 eggs, the eggs are holding that whole cake up, and no swap will fully save it. For those, I bake a recipe that was made to be eggless from the start, like the tested ones in King Arthur’s egg-free baking collection.
Why You Can Trust These Swaps: Tested in My Own Kitchen
I am Amina, the recipe developer and culinary problem-solver behind CookingSubstitutes, with over a decade of cooking through dietary restrictions, tiny kitchens, and last-minute crises. Every swap in this guide was baked by me, most of them many times, in a normal home oven with normal home tools. When I say the applesauce brownie came out fudgy, it is because I cut a warm slice, ate it standing at my counter, and wrote the note right then. The fails are in my notebook too, and they are why the tips in this guide are so specific.
Amina’s Hacks
Speed Hack: I freeze aquafaba and flax gel in ice cube trays. One cube is about 2 tablespoons, so I pop out what I need and keep baking, with no new can to open and no fresh gel to mix.
Budget Hack: Never pour chickpea liquid down the drain. It is a free egg swap hiding inside a can you already bought. Ground flax is my other budget star, because one small bag makes dozens of flax eggs for very little money.
No-Mess Hack: I mix my flax and chia eggs right in the measuring cup I will pour from. One cup to wash, no extra bowls on the counter, and the gel slides out clean every time.
Questions People Ask Me
What can I use instead of eggs in a cake?
Yogurt gives the softest crumb in my cake tests, and the soda and vinegar team gives the best lift for light cakes. For a standard cake with 2 eggs, swap each egg for 1/4 cup of yogurt, keep the rest of the recipe the same, and do not overmix.
Which swap is best for cookies?
Flax eggs and store-bought replacer tie at the top of my cookie tests. Flax adds a tiny nutty taste that suits oat and chocolate cookies, while the powder stays fully neutral. My cookie guide, linked above in swap 13, has the full side-by-side results.
What is the healthiest swap on this list?
Flax and chia, in my view. They add fiber and healthy fats with very few calories, and they work in most everyday baking. Aquafaba is the lightest of all, with almost no calories, but it is a lift swap more than a full egg swap.
Can I swap eggs in a recipe with 4 or more eggs?
I do not recommend it. With that many eggs, the eggs are the structure of the dish, and swaps can turn it flat, dense, or gummy. Pick a tested eggless recipe instead. This is the one case where the kind choice is a new recipe, not a swap.
How do I make a flax egg?
Stir 1 tablespoon of ground flaxseed with 3 tablespoons of water, rest it 5 to 10 minutes until it turns thick like gel, then use it in place of 1 egg. If you grind whole seeds at home, grind them fresh, because ground flax slowly loses its binding power in the bag.
Your Kitchen, Your Rules
The whole point of baking at home is making it work for YOU. Not standing in front of an empty egg carton like the recipe is over, and not running to the store for one small thing.
You don’t need eggs to bake a soft cake, a chewy cookie, or a brownie that disappears in one evening.
You need the right swap for the job, an amount you can trust, and a baker who is willing to try once.
You already have all three.
Here’s what to do next:
- 📌 Pin this post so you have it next time a recipe calls for eggs you don’t have
- Open your pantry right now and find which of these 13 swaps you already own
- Try ONE eggless bake this week using that swap
- Adjust based on the guide above (more lift for light cakes, stronger binders for dense bakes)
- Feel proud that you adapted instead of giving up
Remember: Professional bakers adapt recipes constantly based on what they have on hand. Home bakers can too.
The egg doesn’t make the bake — you do.

P.S. — What’s the strangest swap that ever worked in your kitchen? I once used mayonnaise in a cake mix for guests and told nobody until the plates were clean. It worked perfectly. Tell me your creative solutions in the comments, and keep this guide close, because the best egg substitutes for baking are almost always already sitting in your kitchen.
