Substitute for Heavy Cream: Make 1/2 Cup for Cooking

This quick heavy cream substitute combines whole milk and butter to make about 1/2 cup for sauces, soups, casseroles, and many baking recipes. It adds dairy richness, but it cannot be whipped like heavy cream, so it works best when a recipe uses cream as an ingredient rather than relying on it for volume or a fluffy topping.

Ingredients

1/3 cup (79 ml) whole milk, preferably not skim
2 tablespoons plus 2 teaspoons (38 g) unsalted butter

Instructions

Measure the milk. Pour 1/3 cup (79 ml) whole milk into a small bowl or measuring cup. Have it ready before melting the butter so the butter does not sit and cool for too long.
Melt the butter gently. Place 2 tablespoons plus 2 teaspoons (38 g) butter in a small microwave-safe bowl and heat in short bursts until just melted, about 1 minute total. Alternatively, melt it in a small saucepan over low heat, then take the pan off the stove. Do not let the butter bubble, brown, or separate.
Let the butter cool briefly. Set it aside for about 1 minute. It should still be liquid but no longer piping hot. Very hot butter can warm the milk abruptly and make the mixture harder to blend smoothly.
Whisk into the milk. Slowly drizzle the melted butter into the milk while whisking continuously. Whisk for about 1 minute, until the mixture looks evenly blended and slightly creamy. Use it promptly in a recipe calling for 1/2 cup heavy cream; whisk again if it stands and begins to separate.

Tips

Use it where cream is cooked into a dish. This mixture is useful in creamy pasta sauces, soups, savory casseroles, and some cakes or quick breads. It is a practical ingredient swap, not a perfect duplicate of heavy cream: its texture, fat level, and behavior under heat differ. It will not hold air or form peaks, so do not use it for whipped cream, mousse that depends on whipped cream, or a topping that needs to stay fluffy.
Choose whole milk for the closest result. Whole milk gives the mixture more body than skim milk. Two-percent milk can work in a forgiving soup or sauce, but the result will be a little less rich and may seem thinner. Skim milk is a poor choice when the creaminess is central to the dish.
Keep the heat gentle. The butter should be melted, not browned, and the finished mixture should be whisked into the recipe rather than boiled on its own. If a sauce is simmering, lower the heat and add the substitute gradually. Hard boiling can encourage separation, especially in a thin sauce.
Adjust seasoning for salted butter. Unsalted butter makes the salt level easier to control. If salted butter is what you have, use it, then taste the finished dish before adding more salt. Avoid trying to fix a separated mixture by adding extra butter; whisking it into the recipe or blending the sauce is usually more helpful.

Serving Suggestions

Stir the substitute into a soup near the end of cooking, allowing it to heat through gently rather than boil for a long time. It works in many blended vegetable soups and in brothy soups that benefit from a creamier finish. For a particularly acidic soup, such as one with a lot of tomato or wine, add the mixture slowly over low heat; acidity and high heat can make dairy look grainy or split.

For pasta, add it to a warm sauce along with a splash of pasta water if the sauce needs loosening. The pasta water helps the sauce cling, while the milk-and-butter mixture contributes richness. It can also be stirred into mashed potatoes, a savory casserole filling, or a pan sauce that calls for a small amount of cream. In baking, measure it as you would the cream listed in the recipe, but expect some recipes to have a slightly different crumb or browning because this is not identical to cream.

Use the substitute in a dish that will be served hot or warm, and avoid using it as a stand-alone cold cream topping. If a recipe specifically depends on the high fat content of heavy cream—for example, a ganache with a precise set, a reduction that must thicken substantially, or a custard designed around cream—the swap may change the final texture. For the most dependable result, choose a recipe where the cream is one of several liquid or enriching ingredients.

Variations

For a slightly lighter version: Use 1/3 cup (79 ml) of 2% milk with the same 2 tablespoons plus 2 teaspoons (38 g) butter. It will be less rich than the whole-milk version, so it is best in soups, sauces, or casseroles where other ingredients provide body. Avoid skim milk if you want the mixture to feel creamy.

For a dairy-free cooking swap: Use an unsweetened, unflavored plant milk and a dairy-free butter alternative in the same quantities. Oat or soy beverages tend to be more substantial than many almond beverages, but products vary in thickness and flavor. Check the package for added sugar or vanilla, which would be noticeable in savory food. This variation still will not whip, and it may separate more readily when heated.

For a tangier result: A mixture of plain, unsweetened yogurt and milk can replace cream in some dips, dressings, and gently heated sauces, but it is not a direct match for this butter-and-milk recipe. For a half-cup amount, start with 1/4 cup (60 g) plain yogurt and enough milk to thin it to the texture you need. Use full-fat yogurt for better body, and stir it in off the heat or over very low heat to reduce the chance of curdling. The tang will be more pronounced than with cream.

For recipes that need thickness rather than richness: Milk thickened with a small amount of flour or cornstarch can work in some sauces, but it changes both the method and flavor. It is not the same substitution and should not be poured into a baking recipe in place of the milk-and-butter mixture without adjusting the other ingredients. Pick the alternative according to what the recipe needs: fat and richness, or a thickened sauce.

Storage and Reheating

This substitute is best made just before using because butter can firm up as it cools and the mixture may separate. If you need to prepare it ahead, transfer it to a clean, covered container and refrigerate it within 2 hours. Keep it refrigerated at 40°F (4°C) or colder and use it within 3 days for best quality. The butter may solidify, and a thin layer or uneven texture is normal after chilling.

To bring it back together, warm it gently in a small saucepan over low heat or in short microwave bursts, stirring between each burst. Do not let it boil. Whisk until smooth, then add it to your recipe. If it remains slightly separated, whisk it into the warm dish or use an immersion blender on the sauce if appropriate. Discard it if it has been left at room temperature for more than 2 hours, or if it develops an off smell or appearance.

Freezing is possible, but it is not ideal: thawed milk and butter can separate and may need vigorous whisking or blending. If you freeze a portion, use a sealed freezer-safe container and thaw it in the refrigerator, then use it promptly. Do not refreeze a thawed portion. For a recipe that needs a smooth, dependable sauce, making a fresh batch takes only a few minutes and usually gives a better texture.

Frequently Asked Questions

Can I use this instead of heavy cream in any recipe?

No. It is most reliable when cream is mixed into a cooked sauce, soup, casserole, or forgiving baked good. It does not whip, and it may not provide enough fat or stability for recipes such as whipped cream, some custards, ganache, or sauces that rely on a long reduction. If the recipe needs cream to set or hold air, choose a substitute designed for that purpose or use actual heavy cream.

Will this make whipped cream?

No. Whipping cream needs a high enough fat content to trap and hold air, and this milk-and-butter mixture does not recreate that structure. Chilling it or whipping it longer will not turn it into a dependable whipped topping. Use heavy whipping cream, or a suitable non-dairy whipping product, when the recipe needs soft or stiff peaks.

Can I make this with margarine?

You can use a block-style margarine or dairy-free butter alternative, but the result may be softer or saltier depending on the product. Spreads sold in tubs can contain more water and may make the mixture thinner, so they are less predictable. Choose an unsalted product when possible, melt it gently, and use the substitute in a cooked dish rather than a recipe that depends on exact fat content.

Why did my mixture separate?

Butter and milk do not stay perfectly blended without continued mixing, so a little separation after standing or chilling can happen. Whisk it again before use. Separation is more likely if the butter was very hot, the mixture was boiled, or it was added quickly to a very hot or acidic dish. Lower the heat and whisk while adding it gradually; blending the finished sauce can help if it is suitable for blending.

How much substitute does this recipe make?

The quantities are intended to replace about 1/2 cup heavy cream in a recipe. Measuring can vary slightly with the way butter melts and the size of your measuring cup, so if the recipe requires a very exact liquid volume, stir the mixture thoroughly and measure the finished amount before adding it. For a larger amount, scale both ingredients evenly rather than adding extra butter alone.
