Dairy-free butter substitutes in baking and where each fails

Published 2026-10-21, updated 2026-10-21

Butter is more than fat. It is roughly 80 percent fat and most of the rest is water, and it is solid when cold, soft at room temperature and liquid when hot. Each of those behaviours matters somewhere in baking. No single dairy-free swap copies all of them, so the right choice depends on what the butter is doing in your recipe. This guide covers the main options, the amounts to use, and the bakes where each one tends to go wrong.

What butter does in a bake

Flavour and richness: butter carries flavour and gives baked goods a rounded taste.
Air: creaming soft butter with sugar traps tiny air bubbles that expand in the oven and give cakes and cookies their lift and fine texture.
Tenderness: fat coats flour proteins and shortens gluten strands, which is why it is called shortening.
Flakiness: in pastry, cold solid butter in pieces melts in the oven and the water in it turns to steam, leaving layers.
Spread and browning: the water, milk solids and sugars in butter influence how cookies spread and how deeply they brown.

A substitute that is liquid (oil) cannot be creamed or laminated. One that is solid but very soft (tub spread) can spread too far in cookies. Matching the swap to the job is the whole skill.

The options at a glance

Dairy-free substitutes for 1 cup (about 225 g) of butter
Substitute	Amount	Best for	Where it fails
Vegan butter block or stick	1 cup (225 g), same as butter	Almost everything: cakes, cookies, shortbread, pastry, frosting	Brands differ in fat and water content, so spread and flavour vary. Some are salted.
Vegan butter in a tub (soft spread)	Same amount, with care	Muffins and quick breads that melt the butter	Higher water content and soft texture make cookies spread and pastry greasy.
Refined coconut oil, solid	Same volume as butter	Pie crust, biscuits, scones, some cookies	It is 100 percent fat, so bakes can feel drier and crumble. Melts at about 24 C (75 F), so warm kitchens soften it quickly. Unrefined tastes of coconut.
Liquid oil (neutral, such as sunflower or light olive)	About 3/4 cup (180 ml) for 1 cup butter	Recipes that call for melted butter: brownies, muffins, quick breads, some cakes	Cannot be creamed, so it will not give lift in creamed-butter recipes. Cookies spread flat and can taste greasy.
Unsweetened applesauce	Replace up to half the butter, same volume	Muffins, quick breads, dense cakes, brownies	Gives a moist, cakey, denser crumb with less browning and no crisp edges. Never works alone in cookies or pastry.
Nut or seed butter	Recipe-specific only	Cookies and bars written for it	Strong flavour, and nuts or seeds are allergens.

Vegan butter blocks: the closest swap

Block or stick-style vegan butter is built to behave like butter. It is firm when cold, creams well and can be used one for one by weight or by the markings on the wrapper. For most recipes, this is the first thing to try.

What to check on the pack: whether it is salted (reduce added salt a little if so), whether it is labelled vegan or dairy-free (some table spreads contain milk ingredients), and for coeliac or allergy needs, the full ingredient list. Fat content is printed on many packs. Higher-fat blocks, closer to butter's roughly 80 percent, generally behave more like butter in pastry and cookies.

Keep the temperature the same as the recipe says for butter. If the recipe says cold, cube it and keep it in the fridge until the last moment. If it says softened, leave it out until it gives under a finger but still holds its shape. Some vegan butters soften faster than dairy butter, so check it sooner.

Oil: only for melted-butter recipes

Oil is 100 percent fat and butter is not, so a common rule of thumb is to use about three quarters of the butter's volume in oil. For 1 cup of butter, that is 3/4 cup (180 ml). The remaining water in the butter is, in effect, made up by the other wet ingredients, so you usually do not need to add water.

This works where the recipe already uses melted butter: brownies, many muffins, banana bread, some one-bowl cakes. It is a poor match when the method says to cream butter and sugar, because liquid oil holds no air. Choose a neutral-tasting oil unless you want the flavour of olive oil, as in some citrus or herb bakes.

Coconut oil: useful, with caveats

Solid coconut oil is the nearest plant fat to butter in pastry because it is firm when cool. Refined versions have almost no coconut taste; unrefined ones taste distinctly of coconut. For pie crust and biscuits, chill it until firm and rub it in like butter.

It melts at around room temperature, so keep it cold while working. It has no water in it, so a crust made with it can be crumblier and less flaky than one made with butter. If your dough feels dry, add cold water a teaspoon at a time.

Applesauce: replace part of the fat, not all

Unsweetened applesauce adds moisture and some binding, so it lets you cut fat. A sensible limit is to replace up to half the butter with the same volume of applesauce. Replacing all of it produces a gummy, dense, pale bake. It also does nothing for crisp edges or flakiness, so skip it in cookies meant to snap and in pastry.

If the applesauce is sweetened, reduce the sugar slightly. The bake will brown less and keep soft for longer.

Which bake, which swap

Choosing a butter substitute by bake
Bake	Good choice	Avoid	Tip
Creamed cakes (sponge, vanilla, lemon)	Vegan butter block	Oil, applesauce alone	Cream with sugar until pale before adding other ingredients.
Cookies	Vegan butter block	Tub spread, all oil	Chill the dough for 30 minutes if cookies spread too much.
Shortbread	Vegan butter block with higher fat	Oil, applesauce	Butter flavour matters here, so choose a good-tasting block.
Pie crust and biscuits	Cold vegan block or solid refined coconut oil	Oil, tub spread	Keep everything cold and handle the dough lightly.
Brownies, muffins, quick breads	Oil, or part oil and part applesauce	None really	These are forgiving and suit melted fat.
Buttercream and frosting	Vegan butter block	Oil, coconut oil alone	Beat for several minutes. In warm rooms the frosting softens quickly.
Laminated pastry (croissants, puff)	Specialist vegan block designed for lamination	Everyday blocks	Plain blocks often melt out and make greasy results.

Troubleshooting

Cookies spread flat: the fat was too warm or too soft. Chill the dough, use a block rather than a tub, or add a tablespoon of flour.
Cake is dense: the fat could not be creamed, or you replaced too much with applesauce. Use a block and cream it well.
Pastry is greasy or tough: the fat warmed up before baking, or too much water was added. Chill and rest the dough.
Bake tastes coconutty: switch to refined coconut oil or a block.
Bake is too salty: many vegan butters are salted. Reduce the added salt in the recipe a little.
Bake is dry and crumbly: coconut oil or oil alone can do this. Add a splash of plant milk or part applesauce where suitable.

Allergen and gluten-free notes

Dairy-free is not allergen-free. Some vegan butters contain nuts or soy, and some are made in facilities that handle gluten or milk. If you are baking gluten-free, butter swaps work the same way, but gluten-free doughs are more fragile, so chill them well. Look at the flour and gum advice in the gluten-free flour blends guide. For allergies or coeliac disease, rely on ingredient labels and your doctor or dietitian.

What this guide is based on

That butter is roughly 80 percent fat and that oil is 100 percent fat is general food knowledge, and the three-quarters rule for swapping oil is a commonly published rule of thumb. It is not a result from our own test baking.
Using vegan block butter one for one, replacing up to half the butter with applesauce, and the approximate melting point of coconut oil are widely published, general cooking knowledge.
The 'Where it fails' notes and the bake-by-bake choices are judgements from how each fat generally behaves, offered as a starting point. Brands vary, and we have not baked every combination for this guide.
Allergy and coeliac statements are general. Read ingredient labels and ask a doctor or dietitian about your own needs.
