Not every dairy free butter substitute behaves the same way once it hits heat or a mixing bowl. A swap that makes perfect sauteed vegetables can turn a cookie into a greasy puddle, and a swap that saves a pie crust can ruin a buttercream. The right choice depends on the job, not just on what is in your pantry.
Quick answer: For most baking, a vegan block-style butter works as a 1:1 dairy free butter substitute in cookies, cakes and frosting. For sauteing, use refined coconut oil or olive oil. Shortening gives flakier cookies and crusts but tastes waxy in frosting. Add a pinch of salt if your swap is unsalted.
| Substitute | Ratio to butter | Best jobs | Salt/water adjustment | Common failure mode |
|---|---|---|---|---|
| Vegan block butter (stick style) | 1:1 | Cookies, cakes, frosting, sauteing | Often already salted, check the label first | Can be softer than dairy butter, so dough may spread more if overworked or warm |
| Refined coconut oil, solid | 1:1 by volume | Cookies, pie crust, low to medium heat sauteing | Add a small pinch of salt if using unsalted | Greasy pooling in warm kitchens, low smoke point for high heat frying |
| Virgin or unrefined coconut oil | 1:1 by volume | Same as refined, when coconut flavor is welcome | Same as refined coconut oil | Same greasy risk plus a noticeable coconut taste in savory dishes |
| Olive oil | 3/4 cup oil per 1 cup butter | Sauteing, savory quick breads, some muffins | Reduce other liquid slightly, add a pinch of salt | Dense, greasy crumb in cookies and cakes, unsuitable for laminated dough |
| Vegetable shortening | 1:1, plus 1 to 2 tablespoons water per cup | Pie crust, cutout cookies, some frosting bases | Always add salt since shortening has none | Waxy mouthfeel and flat flavor, especially noticeable in frosting |
| Tub-style vegan margarine (spreadable) | Not recommended 1:1 for baking | Toast and spreading only | Not applicable | High water content makes cookies spread thin and greasy |
Dairy free butter substitute options by job
Think of the swap as answering one question: does this job need solid fat that holds air and shape, or does it just need fat for moisture and flavor. That single distinction explains most of the failures below.
Cookies
Vegan block butter is the closest structural match because it creams with sugar and holds air the way dairy butter does, which is what gives cookies their rise and chew. Plan on similar bake times to a dairy butter version, but check doneness by edge color and a slight give in the center rather than the clock, since brands vary in water content. Solid coconut oil works as a 1:1 swap too, though cookies made with it tend to spread a bit more if your kitchen runs warm, since coconut oil softens at a lower temperature than butter. Shortening produces a firmer, less spreading cookie, which is useful for cutout shapes but can taste flat without extra vanilla or salt.
Cakes and quick breads
Vegan block butter is again the safest 1:1 choice for creaming methods where butter and sugar are beaten together first. Oil-based cakes tolerate olive oil reasonably well since the recipe already expects a liquid fat, but reduce it slightly from a straight 1:1 swap and add a touch more leavening if the crumb turns dense. Coconut oil works in cakes that suit its flavor profile, though it needs to be measured while solid, not melted, if the original recipe calls for creaming rather than whisking.
Frosting and icing
This is the job where the swap choice matters most for taste, not just texture. Vegan block butter whips into a frosting closest to traditional buttercream. Shortening whips light and holds shape well in warm rooms, which is why it shows up in bakery-style frosting, but it can leave a waxy film on the tongue that vegan butter and blends of vegan butter with shortening tend to avoid. Straight oils are not workable for frosting since they never firm up enough to hold a shape.
Sauteing and pan work
For stovetop cooking, oils generally outperform solid fats because they handle heat more predictably. Refined coconut oil and olive oil both work well for medium heat sauteing, but watch the pan rather than a fixed number, since smoke point varies by refinement level and by how hot your specific burner runs. If a recipe calls for finishing a seared protein in butter, such as the browning step in a dish like pressure cooked chicken breast that gets a quick sear afterward, a vegan block butter melts and browns closer to the real thing than a pure oil does. A kitchen thermometer helps confirm oil is in a safe sauteing range rather than approaching its smoke point, which matters more with unrefined oils that smoke sooner.

What changes the ratio
- Brand and formulation: Vegan block butters vary in water content between brands, which changes how much a dough spreads. Check the package for whether it is labeled as a baking stick versus a spreadable tub.
- Room temperature: Coconut oil based substitutes soften and re-solidify with small temperature swings, so a dough that behaves in a cool kitchen can turn greasy in a warm one.
- Salted versus unsalted: Most dairy free substitutes are salted by default. If a recipe was written for unsalted butter, either buy an unsalted version of your substitute or reduce added salt elsewhere in the recipe.
- Solid versus liquid at swap time: Recipes that call for cold, cubed butter for a flaky texture need a solid fat swap, not a melted one. Shortening or refrigerated coconut oil, cut cold, work better here than melted oil.
- Water content of the original fat: Butter is roughly 80 percent fat and the rest water, while oils and shortening are close to 100 percent fat. This is why a straight oil swap for solid butter is not a true 1:1 by volume in most baking applications.
Common mistakes and failure modes
The most common mistake is substituting a spreadable tub margarine, meant for toast, into a baking recipe that expects a firmer stick butter. The extra water in tub margarine makes cookies spread thin and greasy and can prevent cakes from setting properly.
A second common mistake is skipping the salt adjustment. Shortening and some unsalted vegan butters have little to no sodium, and a recipe built around salted dairy butter will taste flat without a small addition, usually a pinch per stick of substitute.
A third mistake is using a straight oil in a job that needs a solid fat structure, such as pie crust or laminated pastry. Oil coats flour differently than a solid fat cut into pieces, which prevents the flaky layers that come from pockets of solid fat melting during baking.
Finally, greasy or oily finished baked goods are almost always a temperature problem rather than a bad substitute. Coconut oil based doughs benefit from a short chill before baking, similar to how a dairy butter dough is chilled, to keep the fat from melting out too early in the oven.
FAQ
Can I substitute coconut oil for butter in cookies?
Yes, solid refined coconut oil works as roughly a 1:1 swap for butter in most cookie recipes. Expect slightly more spread in a warm kitchen, and chill the dough for a short period before baking if the cookies come out flatter than you want.
See kitchen scale options on Amazon if you want to measure solid fat swaps by weight instead of volume, since that reduces guesswork with denser substitutes.
What is the best butter substitute for baking cakes?
A vegan block-style butter designed for baking is generally the best all-around choice for cake batters, since it creams with sugar similarly to dairy butter and holds air for rise. Oil works in recipes already written for oil, but is a poor swap in a creaming-method cake recipe.
Does dairy free butter work for frying and sauteing?
It can, but plain oils such as refined coconut oil or olive oil are usually more reliable for stovetop cooking than solid vegan butter blocks, which can burn or separate at higher heat. Watch the pan rather than a set time, since burner strength and oil refinement both affect how quickly a fat approaches its smoke point.
How much salt do I need to add when using an unsalted substitute?
There is no single published figure for this since it depends on the recipe and the brand of substitute, but a common starting adjustment is a small pinch, roughly an eighth of a teaspoon, per stick-equivalent of unsalted fat used in place of salted butter. Taste the batter or dough where food safety allows, and adjust from there.
Practical recommendation
Keep two substitutes on hand rather than one. A vegan block-style butter covers cookies, cakes and frosting closely enough to swap 1:1 in most recipes, and a neutral or refined oil covers sauteing and pan work where a solid fat is not necessary. Shortening is worth keeping only if pie crust or cutout cookies are a regular project, since its flavor is the weakest link in frosting and quick breads. If a swap comes out greasy or thin, the fix is almost always temperature, salt, or matching solid-to-solid and liquid-to-liquid rather than switching brands again.
