Use milk instead of evaporated milk at 1:1, diluted half with water. Evaporated milk and milk do similar work in a recipe, but they are not identical, and the ratio is what makes the swap succeed. This guide gives the exact ratio, an equivalence table for every amount you will need, what changes in the finished dish, and when you should not make the swap at all. All ratios on this page come from the CookScale substitution data, and every result is approximate; taste the dish before serving, and adjust the seasoning if the swap changes the flavour.
Evaporated milk to Milk: equivalence table
The table below scales the ratio — 1:1, diluted half with water — to every amount you will need, from a quarter of a cup up to three cups. Use the row that matches your recipe, and do not guess the scaling in your head, because a small error in the ratio grows with the size of the recipe.
| Evaporated milk needed | Milk | Water |
|---|---|---|
| 1/4 cup | 2 tbsp | 2 tbsp |
| 1/2 cup | 1/4 cup | 1/4 cup |
| 1 cup | 1/2 cup | 1/2 cup |
| 2 cups | 1 cup | 1 cup |
| 3 cups | 1 1/2 cups | 1 1/2 cups |
When a recipe calls for an amount that is not in the table, scale the ratio proportionally: work out how many cups of evaporated milk the recipe needs, then multiply the ratio by that number. For a single cup, the ratio is exactly as stated; for half a cup, halve it; for two cups, double it. Keep the recipe scaler open while you cook, and you can scale the whole recipe, including the substitution, in one step.
What changes when you use milk instead of evaporated milk
Milk diluted half with water is thinner and less rich than evaporated milk, which is concentrated milk with about half the water removed. The swap makes the result lighter: in a sauce, the diluted milk gives a thinner, less creamy texture, and the sauce may need a little longer to thicken. In baking, the diluted milk adds less richness, so the crumb is slightly less tender, and the bake may need a little extra fat to match the original. The flavour is the main change: evaporated milk has a slightly caramelised, cooked taste, because it is heated during production, while fresh milk tastes cleaner and fresher. In a soup or a sauce, the difference is subtle, but in a custard or a fudge, where the evaporated milk is doing real work, the swap is more noticeable.
When not to substitute evaporated milk with milk
Do not use sweetened or flavoured plant milk in savoury sauces, and do not expect the same browning in baking. That rule is the most important part of this page, because a substitution that works in one recipe can fail badly in another. Evaporated milk does a specific job in each recipe, and the swap only works when the substitute can do the same job. In a recipe where evaporated milk is the main structure — where it holds the bake together, or where its flavour is the point of the dish — the substitute will not do, and it is better to wait until you have the real ingredient, or to choose a different recipe. In a recipe where evaporated milk is a supporting ingredient, where it adds moisture, richness or flavour but does not carry the dish, the swap usually works well. The test is simple: if removing the evaporated milk would ruin the recipe, do not substitute it; if the recipe would still work without it, the substitute is probably safe.
Why this swap works
Plant milks swap 1:1 in most recipes; sweetened or flavoured versions change the taste. That is the principle behind the swap: the substitute does the same chemical or structural job as the original, even though it looks and tastes different. The acid in an acidic substitute activates baking soda, the fat in a fatty substitute shortens a dough, and the liquid in a liquid substitute hydrates the flour. When the substitute does the same job, the swap works; when it does a different job, the swap fails. The ratio on this page is the amount that makes the substitute do the same job as the original, and it is worth following exactly, rather than guessing, because a small error in the ratio changes the job the substitute does.
Worked examples: evaporated milk to milk in real recipes
1. A creamy soup without evaporated milk
A creamy soup for four needs a cup of evaporated milk, so use half a cup of milk and half a cup of water, mixed together before they go into the pot. The soup will be slightly thinner than the original, because diluted milk is less rich than evaporated milk, so simmer it a little longer to thicken, and taste it before serving. Use whole milk if you have it, because it is closer to evaporated milk than skimmed milk.
2. A batch of muffins that needs evaporated milk
A batch of muffins that needs two cups of evaporated milk takes a cup of milk and a cup of water, mixed together before they go into the batter. The muffins will be slightly less rich than the original, because diluted milk adds less fat, so add a tablespoon of extra butter if you want the richness back. Bake the muffins as usual, and watch the oven, because the crumb may be slightly less tender.
3. A white sauce for a pasta bake
A white sauce for a pasta bake needs half a cup of evaporated milk, so use a quarter of a cup of milk and a quarter of a cup of water, mixed together. Stir the mixture into the sauce over a low heat, and simmer it gently until it thickens, because diluted milk takes a little longer to thicken than evaporated milk. The sauce will be slightly thinner, so add a teaspoon of flour if it needs more body.
How to make the swap
Measure out half the amount of milk and half the amount of water, and mix them together before they go into the recipe. For a cup of evaporated milk, use half a cup of milk and half a cup of water, stirred together until combined. Use whole milk if you have it, because it is richer and closer to evaporated milk than skimmed milk. Pour the mixture into the recipe exactly where the evaporated milk would have gone, and do not change anything else. For a sauce, the diluted milk may need a little longer to thicken, so simmer it gently and stir regularly. For baking, the swap is a straight replacement, but the bake may be slightly less rich, so a tablespoon of extra butter can help.
Common mistakes
The most common mistake is using milk on its own, without the water, which makes the recipe too rich and too thick, because evaporated milk is concentrated and the recipe expects the diluted version. Always dilute half with water. The second mistake is using skimmed milk, which is too thin and makes the result watery; use whole milk if you can. The third mistake is expecting the swap to work in a recipe where the evaporated milk is doing structural work, such as a fudge or a caramel, where the concentration matters; in those recipes, the swap can make the result too soft. Finally, do not use this swap in a recipe where the caramelised flavour of evaporated milk is the point, such as a tres leches cake, because fresh milk tastes completely different.
Frequently asked questions
How do I replace evaporated milk with milk?
Use milk diluted half with water: for a cup of evaporated milk, use half a cup of milk and half a cup of water, mixed together. Evaporated milk is concentrated milk with about half the water removed, so diluting fresh milk gives you a liquid of a similar strength. Use whole milk if you can, because it is richer and closer to evaporated milk.
Can I use milk on its own instead of evaporated milk?
It is better not to. Milk on its own is too rich and too thick for a recipe written for evaporated milk, because the recipe expects the diluted version. Always dilute the milk half with water, or the sauce will be too thick and the bake too rich. The dilution is the whole point of the swap.
Does the swap work in baking?
Yes, in most baking, where the difference is small. The bake will be slightly less rich, because diluted milk adds less fat than evaporated milk, so a tablespoon of extra butter can help. The crumb may be slightly less tender, but the difference is subtle, and most cakes and muffins turn out well with the swap.
Can I use this swap in fudge or caramel?
It is risky. In fudge and caramel, the evaporated milk is doing structural work, and its concentration matters, so the swap can make the result too soft or too thin. For those recipes, it is better to use real evaporated milk, or to simmer the diluted milk first to concentrate it. For soups, sauces and baking, the swap works well.
Is evaporated milk the same as condensed milk?
No. Evaporated milk is unsweetened concentrated milk, while condensed milk is sweetened concentrated milk, with a lot of sugar added. The two are not interchangeable, and using condensed milk in a recipe written for evaporated milk will make the dish far too sweet. Check the tin before you use it.
