Dairy Free Baking Substitutions

Updated August 2026 · Baking Resources

Replacing dairy is mostly about matching fat and water content, not flavor. Milk is roughly 88% water with about 8 grams of fat per cup. Butter is about 80% fat and 16% water. Heavy cream is about 36% fat. Match those two numbers and the swap usually disappears into the recipe.

That is exactly why some dairy free baking substitutions disappear into a recipe and others fall apart. Almond milk instead of whole milk changes the fat by 5 grams a cup, which a muffin absorbs without complaint. A tub spread instead of butter can add 60 grams of extra water to a batch of cookies, and no amount of good technique saves that.

So the rule is simple. Before you swap, ask how much fat and how much water the original ingredient was carrying, then pick a replacement that carries about the same.

Changing more than one ingredient? Our free baking substitutions chart lets you check eggs, fats, dairy and leavening side by side so you do not accidentally change three things at once.

Dairy free baking substitutions start with fat and water

Here is what dairy is actually contributing when a recipe calls for it.

Two practical takeaways come out of that table.

First, milk is mostly water, so plant milks substitute easily. The fat gap is small and easy to close with a teaspoon of oil.

Second, butter is not mostly fat by accident. That 16% water turns to steam in the oven and does real work in biscuits, scones and pastry. Swap butter for pure oil and you lose the water. Swap it for a tub spread and you get far too much.

Weighing rather than measuring makes all of this easier, since gram weights are the only way to compare fats honestly. Our ingredient weights chart has the standard numbers, including butter at 227 g per cup and all-purpose flour at 125 g per cup spoon-and-level.

Milk substitutes: which plant milk to use for what

Plant milks are not interchangeable. They differ in fat, protein and sugar, and protein is the one people forget. Protein is what browns a crust and what sets a custard.

All of them weigh close to 240 g per cup, near enough to water at 236 g per cup for kitchen purposes, so you can swap by weight one to one and be fine.

The thin ones behave differently in enriched doughs. Brioche, cinnamon rolls, challah-style breads and soft dinner rolls lean on milk protein and fat for their soft, close crumb. Rice, almond and carton coconut milk have almost no protein, so an enriched dough made with them proofs faster, browns pale and tears more easily. If you are baking an enriched dough dairy free, use unsweetened soy milk. It is the only plant milk with protein in the same range as dairy, and the difference in the finished loaf is obvious.

For flat batters, muffins, pancakes, brownies and most cookies, use whatever you have. The protein gap does not show.

Watch the sweetened versions. A cup of sweetened vanilla plant milk can add 12 to 15 grams of sugar to a recipe, which is close to a tablespoon. Buy unsweetened for baking.

Butter substitutes: use blocks, never tubs

This is where most dairy free baking goes wrong, so read the warning first.

Vegan tub spreads carry far more water than butter and will ruin a creamed or laminated recipe. Butter is about 80 to 82% fat. Soft tub spreads are often 50 to 60% fat, and light versions can drop to 35%. The rest is water and emulsifiers. Cream a tub spread with sugar and it will not hold air. Laminate it into pastry and it will steam the layers into a soggy block instead of separating them. Cookies made with it spread into thin, cakey puddles.

Buy vegan butter in a foil-wrapped block or stick. The packaging is doing you a favor: block-style vegan butter is formulated at 75 to 80% fat precisely so it can behave like butter.

The 80% rule is just arithmetic. One stick of butter, 113 g, is about 90 g of fat and 18 g of water. So 113 g butter becomes 90 g of oil or shortening plus about 20 g of extra milk or water. Our butter converter does the sticks-to-grams part if you are working from a US recipe.

One more thing worth knowing. Creaming needs a solid fat that stays plastic, not greasy and not rock hard. Vegan butter blocks cream well at cool room temperature, around 65F, which is a touch cooler than dairy butter likes. If yours is soft and slumping, chill it for 10 minutes. The full method is in our guide on how to cream butter and sugar.

Dairy free buttermilk

Buttermilk is doing one main job in most recipes: supplying acid so baking soda can react and release carbon dioxide. You can supply that acid without any dairy at all.

Use 1 cup of unsweetened plant milk, about 240 g, plus 1 tablespoon of lemon juice or white vinegar. Stir and let it sit 10 minutes.

Soy milk is the one that genuinely curdles, because the acid coagulates its protein the way it does with dairy. You will see it thicken and separate slightly, which is what you want. Almond, oat and rice milk have too little protein to curdle much, so they will look thin. That is fine. The leavening still works, because the acid is present whether or not the milk visibly thickens.

If you need thickness as well as acid, whisk 1 tablespoon of dairy free plain yogurt into the mix, or use 3/4 cup plant milk plus 1/4 cup coconut yogurt.

Our full buttermilk substitute guide covers the dairy versions and the acid ratios in more detail, including what changes when a recipe calls for both baking soda and baking powder.

Heavy cream and whipping without dairy

Coconut cream is the reliable option. Everything else on the shelf is a compromise.

Whipping needs a fat that is solid at cold temperature and can trap air in a stable network. Dairy cream does this at about 36% fat. Almond, oat and soy milks cannot do it at all, because their fat is too low and not structured the right way. Full-fat canned coconut milk can, because coconut fat is highly saturated and firms up beautifully when chilled.

Here is the method that works:

1. Buy full-fat canned coconut milk or canned coconut cream. Not the carton beverage, which is mostly water.
2. Chill the unopened can in the back of the fridge for at least 12 hours, and overnight is better. This is not optional. The chill is what separates the fat from the water.
3. Open the can without shaking it. Scoop out only the thick solid layer on top and leave the thin liquid behind. Only the solid part whips. A 13.5 oz can usually gives about 1 cup of solid cream.
4. Whip the solid part cold, with cold beaters, for 2 to 3 minutes until it holds soft peaks.
5. Sweeten with 2 to 3 tablespoons of powdered sugar, which is about 15 to 23 g at 120 g per cup, plus a splash of vanilla.

Two honest warnings. Some brands emulsify their coconut milk so well that it never separates, no matter how long you chill it, so if a can fails you, buy a different brand rather than blaming the technique. And coconut whipped cream tastes like coconut. In chocolate, tropical fruit or spice desserts that reads as a feature. On a lemon tart it can fight the flavor.

The leftover thin liquid is not waste. Use it in place of milk in the same recipe.

For the dairy versions and the fat percentages behind all of this, see our heavy cream substitute guide and our step-by-step on how to make whipped cream.

For cooking and baking rather than whipping, full-fat canned coconut milk stands in for heavy cream one to one by volume. It is about 48 g of fat per cup against cream's 88 g, so it is leaner, but it thickens sauces and enriches ganache well. Cashew cream, blended raw cashews and water at about 1:1, is the neutral-flavored alternative if coconut is wrong for the flavor.

Cream cheese and sour cream alternatives

Be honest with yourself here: texture varies enormously by brand, and some dairy free cream cheeses will not hold in a frosting.

Dairy cream cheese is about 33% fat and firm enough to whip stiff. Plant-based versions are built from wildly different bases. Some are cashew and coconut oil, which are firm and behave well. Some are almond or oat with added starch and gums, which are softer and can loosen into soup the moment you beat them with sugar.

Rules that save a batch of frosting:

• Read the fat number on the label. Aim for 8 g of fat or more per 2 tablespoon serving. Anything much leaner is mostly water and starch, and it will slump.
• Coconut oil based is your friend for frosting. It firms up in the fridge, which is exactly the stability you need.
• Keep everything cold and beat as little as possible. Over-beating breaks the emulsion faster than it does with dairy. Combine, then stop.
• If it loosens, add powdered sugar or 1 to 2 tablespoons of cornstarch, not more fat. Sugar and starch bind water.
• Test a small batch first if the cake matters. A brand that worked last year may have reformulated.

For sour cream, unsweetened coconut yogurt is the best swap in batters, at 1:1 by volume. It brings both acid and fat. Plain unsweetened soy yogurt is a leaner substitute that works in quick breads and cakes but not in anything relying on richness. Cashew cream blended with 1 teaspoon of lemon juice per cup is the best homemade version.

Once your frosting is stable, our guide on how to frost a cake covers the crumb coat and chilling steps that matter even more with a softer dairy free frosting.

Where dairy free is easy, and where it is genuinely hard

Some of this is straightforward. Some of it is not, and pretending otherwise wastes your ingredients.

Easy, often indistinguishable:

• Muffins and quick breads. The fat is usually oil or melted butter already, and the milk is mostly hydration.
• Most drop cookies. Vegan butter blocks handle chocolate chip cookies well.
• Oil-based cakes, including carrot cake, banana bread and most chocolate cakes. Many were already dairy free apart from the milk.
• Brownies. Oil or coconut oil works fine.
• Pancakes and waffles. Any plant milk plus a spoon of oil.
• Fruit crisps and crumbles. Vegan butter or coconut oil in the topping.
• Pie crust. Block vegan butter, cold shortening, or a mix of the two.

Genuinely hard, expect to lose something:

• Laminated pastry, meaning croissants and puff pastry. These need a fat that stays pliable across a wide temperature range while you fold it into paper-thin sheets. Vegan butter blocks can be made to work, but they are less forgiving. Coconut oil shatters when cold and melts fast when warm, which is the worst combination for lamination.
• Caramel. Classic caramel relies on butter's water and milk solids for both flavor and texture. Coconut oil and coconut cream make good caramel, but it is coconut caramel, not a copy.
• Custard and pastry cream. These set on egg proteins working together with milk proteins. Soy milk is the only plant milk with enough protein to come close. Almond, rice and oat versions need extra cornstarch and still set softer.
• Buttercream, especially Swiss and Italian meringue. The fat network is the whole point. Block vegan butter works but is softer than dairy butter at room temperature, so these frostings melt sooner and pipe less sharply. Chill the piped cake.
• Anything where dairy flavor is the point. Cheesecake, panna cotta, dulce de leche. You can make excellent dairy free versions of all three. They are different desserts, and that is fine, but do not expect a copy.

Milk allergy, labels, and cross-contamination

Milk is one of the major food allergens identified under US law, and milk allergy can be severe. If you are baking for someone with a milk allergy rather than a preference, the following matters more than any technique on this page.

"Non-dairy" on a label does not legally guarantee that a product is milk free. In the United States, the term "non-dairy" comes from dairy labeling standards, not from allergen law, and products labeled non-dairy can still legally contain milk-derived ingredients such as caseinate. Non-dairy coffee creamer is the classic example: many contain sodium caseinate, a milk protein.

Read the ingredient list and the "contains" statement every single time. Under the Food Allergen Labeling and Consumer Protection Act, packaged foods sold in the US must declare milk in plain language. The FDA's food allergen labeling guidance explains what manufacturers are required to disclose. Milk hides under names including casein, caseinate, whey, lactose, lactalbumin, ghee, curds and dairy solids.

Shared equipment is a real risk. "May contain milk" and "made on shared equipment" advisory statements are voluntary in the US, which cuts both ways. Their presence is a genuine warning. Their absence is not proof of anything. Dark chocolate, chocolate chips and baking chips are the most common surprise, since most are produced on lines that also run milk chocolate.

Your own kitchen counts too. A mixer bowl, a spatula, a pastry brush or a cooling rack that handled butter can carry enough milk protein to cause a reaction in a sensitive person. Wash with hot soapy water, and use separate equipment where you can.

The label and the manufacturer are the authority, not a recipe site. Formulations change without notice. If a label is unclear, call the manufacturer before you bake. If you are baking for someone else, tell them exactly which brands you used so they can make their own decision.

Worked example: converting a muffin recipe

Here is a standard muffin ingredient list in grams, then the dairy free version, so you can see the fat and water math in practice.

Original, 12 muffins:

Step 1, the butter. 113 g of butter is about 90 g fat and about 20 g water. Two options:

• Vegan butter block: use 113 g, straight swap, no other change. Easiest.
• Neutral oil: use 90 g of oil, then add 20 g of extra liquid to replace the water butter was carrying.

Step 2, the milk. 240 g of whole milk carries about 8 g of fat. Pick your plant milk and close the fat gap:

• Unsweetened soy milk, 4.5 g fat per cup: use 240 g, add 1 teaspoon of oil, about 4.5 g. Or skip it, since the difference is small in a muffin.
• Almond milk, 2.5 g fat per cup: use 240 g and add 1 1/2 teaspoons of oil, about 7 g, to match the original richness.
• Oat milk, 5 g fat per cup: use 240 g as is. Expect faster browning from the extra sugar, so check at the early end of the bake time.

Step 3, add the butter water back if you used oil. Your liquid becomes 240 g plant milk plus 20 g, so 260 g total.

The finished dairy free version using oil and almond milk:

Bake at the temperature the original called for. Most muffins go at 350F, which is 177C or gas mark 4, and oil-based batters brown slightly less than butter ones, so judge doneness with a toothpick rather than color.

The result is a slightly moister, slightly more tender muffin, because oil stays liquid at room temperature while butter sets firm. That difference is real and most people prefer it in muffins.

Working in cups instead of grams? Our grams to cups converter handles the flour densities, which change depending on how you fill the cup: 125 g spoon-and-level, 145 g scoop-and-sweep, 115 g sifted.

If you are also baking gluten free, run one change at a time. Our gluten free baking substitutions guide covers the flour blends and binders, and stacking both swaps at once makes it impossible to tell which one caused a problem.

Frequently asked questions

What is the best dairy free milk for baking?

Unsweetened soy milk, in almost every case. It has 7 to 8 g of protein per cup, close to dairy milk, so it browns and sets the way the recipe expects. Oat milk is the best-tasting runner-up for muffins and cakes. Rice and almond milk are the thinnest and are best kept to recipes where milk is a minor ingredient.

Can I use oil instead of butter in baking?

Yes, in muffins, quick breads, brownies and oil-based cakes. Use 80% of the butter weight in oil, so 90 g of oil for 113 g of butter, then add about 20 g of extra liquid. Oil cannot replace butter in creamed cookies, pie crust, laminated pastry or buttercream, because liquid fat cannot hold air or form layers.

Why did my vegan buttercream turn to soup?

Almost always a tub spread instead of a block, or a low-fat vegan cream cheese. Tub spreads can be 40% water and cannot hold an emulsion once sugar goes in. Use foil-wrapped vegan butter blocks, keep everything cool, and add powdered sugar rather than more fat if it starts to loosen.

Does coconut cream really whip like heavy cream?

Yes, if you chill an unopened can of full-fat coconut milk for 12 to 24 hours and use only the solid layer that rises to the top. A 13.5 oz can gives about 1 cup of usable solid cream. Some brands emulsify so thoroughly that they never separate, so switch brands rather than technique if a can fails.

Is "non-dairy" the same as milk free?

No. In the US, "non-dairy" is a dairy labeling term, not an allergen term, and non-dairy products can legally contain milk-derived ingredients such as sodium caseinate. Non-dairy coffee creamer is the usual culprit. Read the ingredient list and the "contains" statement instead of trusting the front of the package.

How do I make dairy free buttermilk?

Stir 1 tablespoon of lemon juice or white vinegar into 1 cup, about 240 g, of unsweetened plant milk and let it sit 10 minutes. Soy milk visibly curdles because of its protein. Almond and oat milk stay thin, which is fine, since the acid still reacts with the baking soda.

Can I substitute coconut oil for butter one to one?

Not by weight. Coconut oil is 100% fat and butter is about 80%, so use 90 g of coconut oil for 113 g of butter, plus 20 g of extra liquid. Use refined coconut oil unless you want the coconut flavor, and expect a firmer, crisper result because coconut oil sets harder than butter.

What is hardest to make dairy free?

Laminated pastry, caramel, custard and meringue buttercream. All four rely on specific properties of butter or milk protein rather than on generic fat and liquid. You can make good dairy free versions of each, but they will be a different dessert rather than an exact copy, so plan for that rather than fighting it.
