The Short Answer: Not Without Changes

No, you cannot swap sweetened condensed milk for evaporated milk in a 1:1 ratio. The two are different products with different water content and sugar levels. Sweetened condensed milk is thick, very sweet, and has about half the water removed. Evaporated milk is unsweetened, has about half the water removed, and tastes like regular milk. Using sweetened condensed milk where evaporated milk is called for will make your dish too sweet and change the texture.

You can use sweetened condensed milk as a substitute, but you need to adjust the recipe. The most common fix is to thin it with water and reduce the sugar elsewhere in the recipe. How much you adjust depends on what you are making.

Key Takeaways

  • Sweetened condensed milk has added sugar; evaporated milk does not, so a straight swap will make food too sweet.
  • To substitute, mix one can of sweetened condensed milk with about one-half can of water to approximate evaporated milk's consistency.
  • You must also reduce the sugar in your recipe by roughly one-half cup per can of sweetened condensed milk you use.
  • This substitution works best in desserts, coffee drinks, and sauces where sweetness is already expected.
  • For savory dishes, evaporated milk is the better choice, and sweetened condensed milk is harder to adjust without ruining the flavor.

Why These Two Products Are Not Interchangeable

Evaporated milk and sweetened condensed milk start the same way — as regular milk with half the water removed. But they diverge after that. Evaporated milk is canned as-is, with no added sugar. Sweetened condensed milk has sugar added before canning, which also acts as a preservative and makes the product thick and syrupy.

One 12-ounce can of evaporated milk contains roughly 10 grams of naturally occurring milk sugar (lactose). The same size can of sweetened condensed milk contains about 120 grams of added sugar — more than 10 times as much. That difference is why taste and texture change so dramatically if you use one where the other is meant to go.

How to Substitute Sweetened Condensed Milk for Evaporated Milk

If you have sweetened condensed milk on hand and no evaporated milk, you can make it work. The method is straightforward: dilute the sweetened condensed milk with water and cut the sugar in your recipe.

Mix one 12-ounce can of sweetened condensed milk with approximately 6 ounces (three-quarters cup) of water. Stir until combined. This gives you roughly the same consistency and milk flavor as evaporated milk, though it will still be sweeter. Then reduce the sugar in your recipe by about one-half cup. If your recipe calls for less sugar than that, reduce it by half instead.

The exact amount of water you add depends on how thick your recipe needs the milk to be. Custards and puddings need thicker milk; sauces and soups need thinner milk. Start with the three-quarters cup of water and add more if the mixture seems too thick.

Which Recipes Work Best With This Substitution

Sweetened condensed milk substitutes most easily in desserts where sugar is already a major ingredient. Flan, pumpkin pie, sweet potato casserole, and dulce de leche all tolerate the swap well because the added sweetness blends in. Coffee drinks like Vietnamese coffee or café con leche also work because the coffee flavor masks the change.

Cream sauces, caramel sauces, and chocolate sauces can work too, as long as you reduce the sugar in the sauce recipe itself. The key is that the dish should already be sweet or rich enough that the extra sugar does not stand out.

Savory dishes are much harder. If your recipe calls for evaporated milk in a cream sauce for pasta, a soup, or a savory custard, sweetened condensed milk will taste wrong no matter how much you adjust. The sweetness will fight the salt and spices. In these cases, it is better to use a different substitute — heavy cream thinned with milk, or regular milk with a little cornstarch to thicken it.

Other Substitutes If You Have Neither

If you do not have evaporated milk and sweetened condensed milk is not a good fit for your recipe, other options exist. Heavy cream mixed with regular milk in a 1:1 ratio mimics evaporated milk's richness and thickness without the sweetness. Use this in savory dishes, soups, and sauces.

Regular milk thickened with cornstarch also works. Mix one tablespoon of cornstarch with one tablespoon of cold water, then stir it into one cup of milk over low heat until it thickens. This gives you a milk product with body, though not quite the same depth of flavor as evaporated milk.

Powdered milk reconstituted to double strength — two tablespoons of powder per one-quarter cup of water instead of the usual one tablespoon per one-quarter cup — can stand in for evaporated milk in a pinch, especially in baking and desserts.

Adjusting Recipes Beyond Just Sugar

When you use sweetened condensed milk as a substitute, you may need to adjust more than sugar. Some recipes rely on evaporated milk's mild flavor to let other ingredients shine. Sweetened condensed milk's strong sweetness can overpower delicate flavors like vanilla or almond.

If your recipe is sensitive to texture — a custard that needs to set a certain way, or a sauce that needs to reach a specific thickness — the extra sugar in sweetened condensed milk can affect how it behaves. Sugar changes how liquids thicken and how custards set. Start with less of the diluted sweetened condensed milk than the recipe calls for, and add more if needed.

Taste as you go. Sweetened condensed milk substitutes are forgiving in some recipes and finicky in others. If you are making something for the first time with this swap, tasting at each stage lets you catch problems before the dish is finished.

Frequently Asked Questions

Can I use sweetened condensed milk in a cream sauce for pasta?

Not without significant changes. The sweetness will taste out of place in a savory sauce. If you must use it, dilute it with water and reduce the sugar in the recipe, but the result will still taste sweet rather than savory. Heavy cream mixed with milk is a better choice for pasta sauces.

How much water should I add to sweetened condensed milk to make it like evaporated milk?

Start with three-quarters cup of water per 12-ounce can of sweetened condensed milk. Stir well. If the mixture is too thick for your recipe, add more water a tablespoon at a time. If it is too thin, you have added too much.

Do I have to reduce the sugar in my recipe if I use this substitution?

Yes. Sweetened condensed milk contains far more sugar than evaporated milk. If you do not reduce the sugar in your recipe, the dish will be unpleasantly sweet. Cut the sugar by about one-half cup per can of sweetened condensed milk, or by half if your recipe calls for less sugar than that.

Will sweetened condensed milk work in a custard or flan?

Yes, it works well in custards and flans because these desserts are already sweet. Dilute it with water, reduce the sugar in the recipe, and proceed as normal. The result will taste slightly different from one made with evaporated milk, but it will still be good.

What is the best substitute if I do not have either evaporated or sweetened condensed milk?

For savory dishes, mix heavy cream and regular milk in equal parts. For desserts, powdered milk reconstituted to double strength works well. Regular milk thickened with cornstarch also works in most recipes, though it lacks the richness of evaporated milk.
