You can use silken tofu instead of an egg at a ratio of 1/4 cup of blended silken tofu per egg. That is the vegan egg replacer that surprises people most, because it is the one that most closely mimics an egg's protein: silken tofu is soft, smooth and rich in protein, and when it is blended until completely smooth, it adds body, moisture and binding to a batter in a way that fruit purees cannot. It is the egg substitute to use in dense, moist bakes — brownies, chocolate cake, muffins, quick breads — where the egg's job is binding and moisture and the tofu's neutral flavour disappears. It is not a substitute in recipes where the egg is the structure, and this page explains exactly where that line falls.

Silken tofu is different from the firm tofu used in stir-fries. It is soft, custard-like and undrained, with a delicate texture that blends into a smooth cream. That texture is what makes it work as an egg replacer: a quarter cup of blended silken tofu has the body and the protein of an egg, without any flavour of its own. A brownie made with silken tofu instead of eggs is dense, fudgy and rich, and nobody can tell the difference. A chocolate cake made with silken tofu is moist and tender, with a fine crumb. The key is to blend it until completely smooth — any lumps will show up as white specks in the finished bake — and to use silken tofu, not firm or extra-firm, which will not blend smoothly.

The ratio, in a table

The table below converts eggs to silken tofu for the amounts you are most likely to meet. The rule is always the same: 1/4 cup of blended silken tofu per egg. Blend the tofu in a blender or food processor until completely smooth before measuring — do not mash it with a fork, because it will stay lumpy.

Eggs called for Blended silken tofu to use Notes
1 egg 1/4 cup 60 ml, blended smooth
2 eggs 1/2 cup 120 ml
3 eggs 3/4 cup 180 ml
4 eggs 1 cup 240 ml — at the limit
5 eggs 1 1/4 cups Not recommended
6 eggs 1 1/2 cups Not recommended

One large egg weighs about 50 grams, and 1/4 cup of blended silken tofu weighs about 60 grams — a little heavier, because tofu is denser than an egg. If you are weighing ingredients, that is the number to use. A standard block of silken tofu is about 300 grams, which gives about 1 1/4 cups of blended tofu — enough to replace about five eggs, though you should not replace more than three in a single recipe.

Worked examples

Example 1: Vegan brownies that nobody can identify

A brownie recipe calls for 2 eggs. Replace them with 1/2 cup of blended silken tofu. The brownies will be dense, fudgy and rich, with a smooth crumb and no hint of tofu — the chocolate completely covers it. Bake them for the same time, but check them with a skewer, because the extra moisture can make the centre take a minute or two longer to set. Let them cool completely before cutting, because the crumb sets as it cools. This is the best first recipe to try the swap in, because brownies are forgiving and the tofu's protein gives them a structure that fruit purees cannot.

Example 2: A vegan chocolate cake

A chocolate cake recipe calls for 3 eggs. Replace them with 3/4 cup of blended silken tofu. The cake will be moist and tender, with a fine crumb and a deep chocolate flavour. Because the recipe contains baking soda, and the tofu adds moisture, the cake may need an extra minute or two in the oven — test it with a skewer. This is a good recipe for the swap, because the chocolate hides everything and the tofu's protein helps the cake hold together.

Example 3: Muffins with a protein boost

A muffin recipe calls for 1 egg. Replace it with 1/4 cup of blended silken tofu. The muffins will be moist and tender, with a slightly denser crumb than the egg version, and they will be higher in protein — which matters if these are a breakfast muffin rather than a treat. The tofu's neutral flavour means the muffins taste of their flavourings — blueberry, lemon, chocolate chip — rather than of the substitute. Blend the tofu until completely smooth, or you will have white specks in the muffins.

What changes in the result

Three things change when you swap silken tofu for an egg. First, the texture: the bake will be denser and moister, because tofu binds but does not leaven or set the way egg protein does. A cake made with silken tofu will be heavier and more compact than the egg version, and it will not rise as much. Second, the flavour: almost nothing. Silken tofu is flavourless, which is its greatest advantage over fruit purees — it does not add banana, apple or nuttiness, so the bake tastes of its own flavourings. Third, the nutrition: silken tofu adds protein, calcium and iron, and it is low in fat and calories, so the bake is more nutritious than the egg version in some respects, though an egg is also nutritious.

The practical consequence is that silken tofu is the most neutral vegan egg replacer, and the best choice when you want the substitute to disappear. It works in brownies, chocolate cake, muffins and quick breads, where the egg's job is mostly binding and moisture. It does not work in recipes where the egg provides lift, structure or aeration.

When not to substitute

Do not use silken tofu in meringues, custards, angel food cake, or any recipe where egg is the main structure. Silken tofu cannot whip to peaks, it cannot set into a custard, and it cannot provide the lift that beaten eggs give a sponge. Do not use it in a recipe that calls for more than three eggs — beyond that, the recipe relies too heavily on eggs. Do not use firm or extra-firm tofu: it will not blend smoothly, and it will leave lumps in the bake. Use silken tofu only, and blend it until completely smooth. And do not use it if anyone eating the food has a soy allergy — tofu is made from soybeans, and soy allergy is common. The swap is for vegan baking where the tofu's neutrality is an asset, and even there it is best in dense, moist recipes.

One more caution: silken tofu is perishable. Once opened, it keeps in the fridge for up to five days, covered in water that is changed daily. Do not use tofu that smells sour or has gone slimy. And do not blend the tofu hours ahead — blend it just before using it, because it thickens as it sits and the batter will be stiffer.

Frequently asked questions

How much silken tofu do I use instead of 1 egg?

Use 1/4 cup of blended silken tofu for 1 egg — about 60 grams by weight. For 2 eggs, use 1/2 cup; for 3 eggs, use 3/4 cup. Blend the tofu until completely smooth before measuring, and use silken tofu, not firm or extra-firm. Do not use it to replace more than three eggs in a single recipe.

Can I use silken tofu instead of eggs in a cake?

Yes, in a brownie, a chocolate cake, a muffin or a dense cake, where the egg's job is binding and moisture. The cake will be denser and moister than the egg version, and it will not rise as much. In a light sponge cake or an angel food cake, where the egg provides lift and structure, silken tofu will not work — the cake will be flat and dense.

Does silken tofu make baked goods taste like tofu?

No. Silken tofu is flavourless, which is its greatest advantage as an egg replacer. It does not add banana, apple or nuttiness the way fruit purees do, so the bake tastes of its own flavourings. In a chocolate cake, nobody can tell the difference. In a vanilla cake, the tofu is still flavourless — but the cake will be denser, which is the real change.

What is the difference between silken tofu and firm tofu?

Silken tofu is soft, custard-like and undrained, made by coagulating soy milk without pressing it. Firm tofu is pressed to remove water, giving it a dense, chewy texture. Only silken tofu blends smoothly enough to replace an egg — firm tofu will stay lumpy and will not bind a batter properly. Buy silken tofu in the aseptic box (usually in the Asian foods aisle), not the refrigerated firm tofu.

Can I use silken tofu instead of eggs in cookies?

In soft, chewy cookies, yes — the cookies will be softer and more cake-like. In crisp cookies, no — the cookies need the egg's protein for their texture. For cookies, a flax egg is often a better choice than silken tofu, because it binds more strongly and does not add as much moisture.

How long does silken tofu keep?

Unopened, silken tofu in an aseptic box keeps for months at room temperature — check the date on the box. Once opened, it keeps in the fridge for up to 5 days, covered in fresh water that is changed daily. Do not use tofu that smells sour, has gone slimy, or has been open for more than five days.
