After ruining an embarrassing number of cakes, I can finally tell you which egg replacers actually work and which ones are committing crimes against baked goods.
Let me be honest with you. I went into this experiment thinking egg replacers were basically interchangeable. Flax egg, chia egg, aquafaba, whatever. They all bind stuff together, right?
Wrong. So incredibly wrong.
Over the past month, I baked the same vanilla cake recipe 10 times, swapping only the egg replacer. Some results were genuinely impressive. Others produced dense hockey pucks that even my partner's very polite mother couldn't pretend to enjoy.
The vegan baking world is full of advice about egg substitutes, but nobody tells you that context matters enormously. What works in brownies might destroy your muffins. Here's what actually happened when I put these popular options to the test.
1. Aquafaba: the overachiever
Three tablespoons of chickpea water whipped until foamy gave me the lightest, fluffiest cake of the entire experiment. The crumb was tender. The rise was beautiful. I genuinely gasped when I cut into it.
Aquafaba works because it contains proteins and starches that mimic egg whites when whipped. Research on aquafaba's foaming properties shows it can trap air bubbles almost as effectively as traditional egg whites.
For cakes and anything requiring lift, this is your best friend. Just make sure you whip it properly. Lazy aquafaba equals lazy results.
2. Commercial egg replacer (Bob's Red Mill): the reliable coworker
Not exciting, but consistently solid. The cake rose evenly, held together well, and tasted exactly like cake should taste. No weird aftertaste, no strange texture.
These products are specifically formulated for baking, usually combining starches and leavening agents. They're designed to be foolproof. If you're new to vegan baking or just want something that works without thinking too hard, keep a bag in your pantry.
It won't win any awards for innovation, but it won't embarrass you at a birthday party either.
3. Flax egg: the wellness influencer
One tablespoon ground flax plus three tablespoons water, rested until gooey. This is probably the most recommended egg replacer online, and I understand why. It's cheap, healthy, and available everywhere.
But here's the thing. My flax egg cake was noticeably denser than the aquafaba version. Still good, still edible, definitely cake-like. But the crumb was tighter and the texture slightly gummy.
Flax eggs excel in heartier baked goods like oatmeal cookies or banana bread. For delicate cakes, they're trying their best but falling a bit short.
4. Chia egg: the flax egg's mysterious cousin
Same ratio as flax. Similar results, but with tiny visible specks throughout my cake that made it look vaguely like it had a skin condition. Texturally, we're in the same territory as flax. Dense but functional.
Chia eggs work better in darker batters where the specks disappear.
Chocolate cake? Great. Vanilla cake? Your guests will ask questions. The binding power is real, but the aesthetics need consideration. Sometimes baking is about managing expectations and chia eggs require that conversation upfront.
5. Silken tofu: the secret weapon
A quarter cup of blended silken tofu produced a surprisingly moist, tender cake. The texture was slightly different from traditional cake, almost custardy in the best way. Rich and satisfying.
Tofu adds protein and fat, which contributes to that luxurious mouthfeel. It's particularly excellent in brownies and dense chocolate cakes where moisture is a feature, not a bug.
The flavor is completely neutral when blended smooth. This one deserves more attention than it gets in mainstream vegan baking conversations.
6. Mashed banana: the one-trick pony
Half a ripe banana mashed into my batter created something that tasted exclusively like banana cake. Which is fine if you want banana cake. I did not want banana cake. I wanted vanilla cake that happened to use banana as a binder.
The moisture level was good and the binding worked adequately. But banana is a flavor bully. It takes over everything it touches. Reserve this for recipes where banana flavor is welcome or at least not actively unwelcome. Banana bread, banana muffins, banana pancakes. See the pattern?
7. Applesauce: the sneaky moisture bomb
A quarter cup of unsweetened applesauce gave me a cake that was wet. Not moist. Wet.
The center never quite set properly, and the edges overcompensated by becoming slightly tough.
Applesauce can work in some recipes, particularly ones already designed around fruit. But as a straight egg replacement in a standard cake recipe, it throws off the liquid ratio dramatically. You'd need to adjust other ingredients to compensate. For a simple swap, this one requires too much babysitting.
8. Carbonated water: the TikTok trend
I saw this recommended online and figured why not. A quarter cup of sparkling water supposedly adds lift through carbonation. My cake rose initially, then collapsed into a sad crater during cooling.
The science sort of makes sense. Bubbles create air pockets. But those bubbles escape quickly, and there's nothing providing structure once they're gone. Eggs do more than just add air. They provide protein that sets during baking.
Carbonated water is all party, no commitment. Skip it.
9. Vinegar and baking soda: the science experiment
One tablespoon vinegar plus one teaspoon baking soda, added separately to wet and dry ingredients. The reaction creates lift, and honestly, the rise was decent. But the cake tasted faintly metallic and slightly sour.
This combination works better as a supporting player alongside another egg replacer rather than a solo act. The chemical reaction is real, but it can't do everything an egg does. Use it to boost lift in recipes that already have binding covered by something else.
10. Nothing: the control group gone wrong
Just for science, I made one cake with no egg replacer at all. It was flat, crumbly, and fell apart when I tried to remove it from the pan. The pieces tasted fine but structurally, this was a disaster.
Eggs matter. They provide structure, moisture, binding, and lift. Skipping them entirely without compensation produces something closer to a dense cookie than a cake. This confirmed what the whole experiment was about.
Choosing the right replacer for your specific recipe makes an enormous difference.
Final thoughts
After destroying my kitchen and eating way too much cake, here's my hierarchy. For light, fluffy cakes, aquafaba is undefeated. For foolproof everyday baking, commercial egg replacers earn their shelf space.
For dense, rich treats like brownies, silken tofu is underrated gold. Flax and chia work fine in heartier recipes where density is acceptable.
Everything else is situational at best. Banana and applesauce only belong where their flavors make sense. Carbonated water and vinegar-baking soda combos are supporting actors, not leads. And baking with nothing is just optimism without a plan.
The real lesson is that vegan baking isn't about finding one perfect substitute. It's about matching the right tool to the job. Your muffins have different needs than your cookies. Respect that, and your baked goods will respect you back.
