Use butter at a 1:1 ratio, but reduce other liquids slightly

You can swap shortening for butter in most recipes using equal amounts—one cup of shortening becomes one cup of butter. The main difference is that butter contains about 15 to 20 percent water, while shortening is pure fat. This water changes how your baked goods turn out: crusts become flakier, cookies spread a bit more, and cakes may be slightly less tender. For most home baking, these differences are small enough that you won't notice them.

If your recipe calls for shortening plus milk or another liquid, reduce the liquid by about 2 to 4 tablespoons per cup of shortening you're replacing. This prevents your dough or batter from becoming too wet. Start with 2 tablespoons less and add more liquid only if the mixture looks too dry—it's easier to add than to remove.

Butter works best when it's at the temperature your recipe specifies. If the recipe says "softened shortening," use softened butter. If it says "cold shortening," use cold butter straight from the refrigerator. Temperature matters because it affects how the fat mixes into your dough and how your final product bakes.

Key Takeaways

  • Replace shortening with butter using a 1:1 measurement—one cup shortening equals one cup butter.
  • Reduce other liquids in the recipe by 2 to 4 tablespoons per cup of butter because butter contains water that shortening does not.
  • Butter makes baked goods slightly flakier and causes cookies to spread more than shortening does, but the difference is usually small in home baking.
  • Match the butter temperature to what the recipe calls for—softened butter for creaming, cold butter for pastries and biscuits.
  • Unsalted butter is the safer choice so you can control the salt level in your recipe.

Why butter and shortening behave differently

Shortening is 100 percent fat with no water. It has a higher melting point than butter, which means it stays solid longer in the oven. This creates steam pockets that make pie crusts and biscuits flaky and light. Shortening also produces a more tender crumb in cakes because the fat coats flour particles more completely, preventing gluten from developing.

Butter is about 80 percent fat and 15 to 20 percent water, plus milk solids. The water evaporates during baking, which can make crusts less flaky and cakes slightly less tender. However, the milk solids add flavor and can create a richer, more golden color. For most everyday baking, this trade-off is worth it because butter tastes better and is easier to keep on hand.

The milk solids in butter also brown at higher temperatures, which is why butter-based cookies often have darker, crispier edges than those made with shortening. If you prefer a lighter, more delicate cookie, you may want to lower your oven temperature by 25 degrees Fahrenheit when using butter.

Adjusting recipes for pie crusts and pastries

Pie crusts and pastries are where the difference between butter and shortening matters most. Shortening creates a more tender, flaky crust because it doesn't absorb water the way butter does. If you're replacing shortening with butter in a pie crust, use cold butter cut into small cubes and work it into the flour quickly—don't let it warm up. The colder the butter stays, the flakier your crust will be.

You may also want to add an extra tablespoon or two of ice water to your dough because butter's water content is locked inside the fat, not free to hydrate the flour. Mix just until the dough comes together; overworking develops gluten and makes the crust tough. Chill the dough for at least 30 minutes before rolling it out.

For biscuits and scones, the same rule applies: use very cold butter, cut it in quickly, and handle the dough as little as possible. The result will be slightly less tender than one made with shortening, but still delicious and much more flavorful.

Adjusting recipes for cookies and cakes

Cookies and cakes are more forgiving. Replace shortening with butter at a 1:1 ratio and reduce the liquid by 2 to 3 tablespoons. Butter will make cookies spread slightly more and brown a bit faster, so watch them carefully during the last few minutes of baking. If they're browning too quickly, lower the oven temperature by 25 degrees.

For cakes, the swap is nearly invisible. Butter may make the cake slightly less tender and a touch drier, but the flavor improvement usually outweighs this. If you find your cake is too dry, add 1 to 2 tablespoons more liquid next time. Keep notes on what works so you can adjust future batches.

Creamed butter and sugar will look lighter and fluffier than creamed shortening and sugar, which is normal. Cream them together for 2 to 3 minutes until the mixture is pale and fluffy before adding eggs and other ingredients.

Choosing salted or unsalted butter

Use unsalted butter for baking whenever possible. Unsalted butter lets you control exactly how much salt goes into your recipe. Salted butter contains varying amounts of salt depending on the brand—some have a quarter teaspoon per stick, others have more. This makes it hard to predict how salty your finished baked good will be.

If you only have salted butter on hand, reduce the salt in your recipe by about one-quarter teaspoon per cup of butter. Taste your batter or dough if you can (raw eggs aside, most cookie doughs are safe to taste in small amounts), and adjust the salt to your preference.

For cooking and frying, salted or unsalted butter works equally well. The salt difference matters much less when you're cooking savory food because you'll be seasoning the dish anyway.

Butter substitutes when you don't have shortening

Coconut oil is the closest substitute to shortening in terms of how it behaves in baking. It's solid at room temperature and has a high melting point, so it creates flaky crusts and tender cakes much like shortening does. Use it at a 1:1 ratio with no liquid adjustment needed. The flavor will be slightly different—coconut oil adds a subtle coconut taste that works well in some recipes but not others.

Lard, if you can find it, also works well as a shortening substitute. It's pure fat like shortening and creates excellent pie crusts. Use it at a 1:1 ratio with no liquid adjustment. Lard has fallen out of favor in many home kitchens, but it's still available at butcher shops and some grocery stores.

Margarine is not a good substitute because it contains water like butter does, plus additives that can affect texture. Stick with butter or coconut oil for the most reliable results.

Common mistakes to avoid

The biggest mistake is forgetting to reduce the liquid. Butter's water content will make your dough or batter wetter than the original recipe intended. If you don't reduce the liquid, your baked goods may turn out dense, gummy, or spread too much. Start by reducing liquid by 2 tablespoons and add more only if the mixture looks too dry.

Another common error is using melted butter when the recipe calls for softened or cold butter. Melted butter mixes differently into dough and can change the texture of your final product. If you need softened butter, leave it on the counter for 30 to 60 minutes until it's soft enough to press your finger into easily but still holds its shape.

Don't skip the temperature adjustment for cookies. Butter browns faster than shortening, so your cookies may burn on the edges while the centers are still underbaked. Lower the oven temperature by 25 degrees and check them a minute or two earlier than the recipe suggests.

Frequently Asked Questions

Can I use salted butter instead of unsalted in baking?

Yes, but reduce the salt in your recipe by about one-quarter teaspoon per cup of butter. Different brands of salted butter contain different amounts of salt, so the result may vary slightly. For best results, use unsalted butter so you control the salt level exactly.

Why did my pie crust turn out tough when I used butter instead of shortening?

You likely overworked the dough or didn't keep the butter cold enough. Butter needs to stay in small, cold pieces throughout mixing so it creates steam pockets that make the crust flaky. Cut cold butter into small cubes, work it in quickly with a pastry cutter or fork, and chill the dough for at least 30 minutes before rolling.

Do I need to reduce the liquid if I'm using melted butter?

No. Melted butter mixes into dough differently than solid butter, and the water is already distributed throughout. Use melted butter at a 1:1 ratio with no liquid adjustment. However, melted butter produces a different texture than solid butter, so the result may not match the original recipe.

What temperature should my butter be for creaming with sugar?

Butter should be softened—soft enough to press your finger into easily but still holding its shape. This usually takes 30 to 60 minutes on the counter. Softened butter creams with sugar to a light, fluffy mixture that incorporates air and helps your cake or cookies rise. Cold butter won't cream properly, and melted butter won't incorporate enough air.

Can I use butter in a recipe that calls for vegetable oil?

Not directly. Vegetable oil is liquid at room temperature, while butter is solid. If you want to use butter, melt it first and use it at a 1:1 ratio. The result will be different—baked goods made with melted butter tend to be denser and more cake-like than those made with oil. For best results, stick with the oil the recipe calls for.
