Use heavy cream as a milk substitute by diluting it with water so it behaves more like milk in recipes. A common ratio is 1/2 cup heavy cream + 1/2 cup water for each 1 cup of whole milk.

Best use cases

This works best in baking, sauces, soups, and cooked dishes where a little extra richness is fine. It can make the final result thicker and creamier than milk, so it is not always ideal for delicate recipes or drinks.

Simple swap

  • For 1 cup milk , use 1/2 cup heavy cream + 1/2 cup water.
  • For 1/2 cup milk , use 1/4 cup heavy cream + 1/4 cup water.
  • Stir well before adding it to the recipe so the fat and water are evenly mixed.

What changes

Heavy cream has much more fat than milk, so the swap adds richness and body. That can be helpful in mashed potatoes, custards, creamy sauces, and baked goods, but it may slightly alter texture and flavor.

Practical tip

If your recipe depends on milk for a light texture, start with the diluted version and avoid using straight heavy cream unless the recipe is meant to be rich. For coffee or drinks, the result will usually be much thicker than milk.

Quick version

Mix equal parts heavy cream and water to replace milk in most recipes. That is the easiest and safest starting point.
