Out of Milk, one case

Milk substitute for cereal

5 options, ranked, with the exact amount

Use thisBest of 5 options

Use Oat milk

1 cup for every cup of milk

Unsweetened oat milk or soy milk, in the same amount, is the closest pour for a bowl of cereal: oat is the creamiest and mildest, and soy has the most protein. With no plant milk in the house, mix ½ cup evaporated milk with ½ cup cold water, or 1/3 cup dry milk powder with 1 cup cold water, and chill it. Water with melted butter, the baking fix, does not work in a bowl.

What changes5 options

Oat milk

mildly oaty and slightly sweet

The plant milk nearest to dairy in a cold bowl: creamy, mild and naturally a little sweet.

Best for
everyday cold cereal, granola and muesli, anyone who finds soy or almond milk too strong
Prep
Shake the carton before pouring.
Suits
vegan
Where it fails
It has about 2 to 3 g of protein per cup against about 8 g in milk, so the bowl is less filling.

Soy milk

faintly beany, which shows more in a plain cereal than in a sweet one

The closest to milk in body and in protein, at about 7 to 8 g per cup.

Best for
cold cereal, granola, a bowl meant to keep you full
Prep
Shake the carton; soy milk settles.
Suits
vegan
Contains
soy
Where it fails
Plain unsweetened soy milk poured over an unsweetened cereal can taste flat or beany. The original or vanilla carton suits cereal better, with the added sugar that comes with it.

Almond milk

thin and faintly nutty

Thin and light, with a faint nutty taste that suits granola and bran cereals.

Best for
granola, muesli and nutty cereals, a lighter bowl
Prep
Shake it well; almond milk separates more than the others.
Suits
vegan
Contains
tree nuts
Where it fails
It is watery next to milk and has about 1 g of protein per cup. Flaked cereals go soft in it a little sooner.

Evaporated milk + water

close to milk, with a faint cooked, caramel note you can taste when it is cold

Canned milk with the water put back. It is real milk and has the body of whole milk.

Best for
any cereal when the carton is empty, hot cereal
Prep
Use cold water and chill the mix, or pour it over ice for a minute.
Contains
dairy
Where it fails
Poured straight from the can it is twice as concentrated: thick and strong. Sweetened condensed milk is a different can and is not a swap.

Dry milk powder + water

like skim milk, slightly cooked

Instant nonfat dry milk mixed back into milk. It is skim milk, so it is thinner than whole.

Best for
cold cereal from the pantry, hot cereal
Prep
Whisk the powder into cold water until smooth and chill it at least 30 minutes; the flavor improves as it sits.
Contains
dairy
Where it fails
Mixed and poured at once it tastes chalky and can leave lumps.

Water + butter

water, with fat floating on it

The stand-in that works in baking, 1 cup water with 1 tablespoon melted butter, depends on being mixed into a batter.

Best for
baking only, not a cereal bowl
Where it fails
In a cold bowl the butter hardens into flecks on the surface and the cereal sits in plain water.

How it behaves in this recipe

In this recipeMilk

On cereal nothing is cooked, so the swap is judged on taste, body and how it sits in the bowl. That reverses the baking order: plant milks you would hardly notice in a muffin are plain to taste here, and fixes that rely on mixing, such as water with butter, do not work.

Tips for substituting milk

5 tips
  1. Sweet cereal: use an unsweetened carton. The cereal brings the sugar, and an original or vanilla plant milk adds several teaspoons more per cup.
  2. Plain cereal such as shredded wheat or bran flakes: oat milk, or an original soy milk, tastes less flat than unsweetened almond.
  3. Evaporated milk: ½ cup from the can plus ½ cup cold water per cup of milk. A 12 fl oz can makes 3 cups.
  4. Dry milk: 1/3 cup instant powder per cup of cold water, whisked smooth and chilled 30 minutes.
  5. Hot cereal is easier. Oatmeal and cream of wheat cook well in water alone, and a splash of any of these goes on top.

Questions

5 questions

What can I use for cereal if I have no milk at all?

Check the pantry for a can of evaporated milk or a box of dry milk powder: either mixes with water into real milk. Failing that, spoon plain yogurt over the cereal as you would with granola, or eat it dry with fruit.

Can I eat cereal with water?

You can, and it is safe, but it tastes of wet cereal: water adds no body, sweetness or fat. It works better with hot cereal, where oatmeal is cooked in water as the package directs.

Which plant milk tastes most like milk on cereal?

Oat milk is the mildest and creamiest. Soy milk is closest in body and protein and has a faint beany taste. Almond milk is the thinnest. All three pour in the same amount as milk.

Is lactose-free milk a substitute for milk on cereal?

Yes, in the same amount. It is cow's milk with the lactose already broken down, so it pours and tastes like milk, only slightly sweeter. It is still dairy, so it does not suit a milk allergy or a vegan diet.

Can I use half and half or cream on cereal?

Yes. Thin it to match milk: 1/3 cup half and half plus 2/3 cup water per cup, or 3 tablespoons of heavy cream topped up to 1 cup with water. Straight half and half is rich but fine on a small bowl.
