Half and Half Substitute: Exact Mixes for Baking, Custard and Coffee

Baking Resources Editorial · Reviewed by Joan Ramos · Updated October 2026 · 9 min read

The easiest half and half substitute is equal parts whole milk and heavy cream: 1/2 cup of each makes 1 cup. If you want a closer match on richness, use 3/4 cup whole milk plus 1/4 cup heavy cream. No cream? Mix 3/4 cup plus 2 tablespoons of whole milk with 2 tablespoons of melted butter for cooked recipes.

Half and half is just a light blend of milk and cream, so it's one of the simplest dairy items to rebuild at home. Pick how much your recipe needs and what you have in the fridge, and the calculator below works out the exact amounts for you, including dairy-free options.

What half and half actually is

Half and half is a mix of whole milk and cream. In the US it has to contain between 10.5 and 18 percent milk fat, and most cartons land around 12 percent. For comparison, whole milk is about 3.25 percent fat, light cream is usually around 20 percent, and heavy cream is at least 36 percent.

That fat number is the whole story. Half and half gives a recipe more richness and a silkier feel than milk, without the heaviness of cream. So the goal of any half and half replacement is to land somewhere near that 10 to 18 percent range. Go a little over and your custard is richer. Go a little under and your sauce is a bit thinner. Neither is a disaster.

One thing half and half won't do is whip. It doesn't have enough fat to hold air. If you need whipped topping, look at our guide on whipped cream without heavy cream instead.

Milk and cream mixes

Equal parts whole milk and heavy cream

This is the swap most people reach for, and it's the one in our baking substitutions finder. It runs a little richer than store-bought half and half, which most bakes welcome. Custards come out silkier, and coffee tastes creamier. If you're watching fat, use the lighter mix instead.

Three parts milk, one part cream

Mix 3/4 cup whole milk with 1/4 cup heavy cream and you're at roughly 11 percent fat, right in half and half territory. This is the closest everyday match and a smart way to stretch a small carton of cream. The same idea works if you have heavy cream but no milk at all. Our guide on using heavy cream instead of milk shows how to thin it with water.

Lower-fat milk plus cream

With 2% milk, use 2/3 cup milk and 1/3 cup heavy cream. With skim milk, use the same 2/3 to 1/3 split. It lands closer to 12 percent, slightly lighter but still fine for baking and coffee.

Milk and butter, when there's no cream

Butter is about 80 percent fat, so a little of it turns milk into something close to half and half. Melt 2 tablespoons of butter and whisk it into 3/4 cup plus 2 tablespoons of whole milk. That's about 12 percent fat.

The catch is that butter and milk don't truly blend. Without the emulsifiers that keep cream smooth, the butter floats back up as it cools. That's fine in a cooked sauce, a batter or a soup, where everything gets stirred and heated. It's not great in cold uses like coffee or a no-cook dressing, where you'd see little flecks of fat. Use unsalted butter if you have it. Otherwise it adds a small pinch of salt, which few recipes will notice.

Light cream, evaporated milk and plain milk

Light cream

Light cream sits around 20 percent fat, so mixing it half and half with whole milk lands you right at 12 percent. If you only have light cream, you can use it straight for a richer result.

Evaporated milk

Evaporated milk is milk with about 60 percent of its water cooked off, so it's thicker and richer than it looks, at about 7 to 8 percent fat for the whole-milk kind. Use it 1 for 1. It has a faint cooked, caramel-like flavor that tastes right at home in pumpkin pie, sweet potato pie and creamy casseroles. Our page on evaporated milk covers how it behaves in baking. Don't mix it up with sweetened condensed milk, which is very sweet and won't work here.

Whole milk on its own

In muffins, pancakes, quick breads and most cakes, half and half is only there for a little richness. Plain whole milk works 1 for 1. The crumb is a bit less tender, but most people won't notice. Just don't use plain milk in custards or panna cotta, where the fat is doing real work.

Dairy-free half and half options

For a dairy-free version, mix 1/2 cup of full-fat canned coconut milk with 1/2 cup of an unsweetened plant milk like oat, soy or almond. Shake the coconut milk can well first. That blend lands near 10 percent fat and acts a lot like half and half in baking, soups and coffee. Coconut flavor is mild but noticeable, so it suits spiced and chocolate bakes best.

Soy milk on its own is the next best choice for baking because its protein helps with structure. Oat milk is lovely in coffee, especially the thicker "barista" styles, but it's thin in custards. For whipping or heavier jobs, our list of vegan heavy cream substitutes has stronger options, and our dairy-free baking substitutions guide covers the butter and milk in the rest of the recipe.

Which swap for baking, custards and coffee

A quick word on coffee, since it's the most common use. Equal parts milk and cream is the closest taste. Whole milk alone tastes thinner but works fine. Very hot, very acidic coffee can sometimes make cream mixes look feathery. Let the coffee cool for a minute, or warm the mix first, and it stays smooth. In cheesecake, a creamy mix also helps the batter stay smooth, and our guide on preventing cheesecake cracks covers the baking side.

Worked example: pumpkin pie for Thanksgiving

Say your pumpkin pie calls for 1 1/2 cups of half and half, and the carton in the fridge is empty. You have whole milk and a small carton of heavy cream.

1. Pick the mix. Equal parts gives the richest custard, so use 3/4 cup whole milk plus 3/4 cup heavy cream.
2. Or stretch the cream. If you only have a little cream, use the 3 to 1 mix: 1 1/8 cups (1 cup plus 2 tablespoons) milk and 3/8 cup (6 tablespoons) cream.
3. Whisk and use cold. Mix the milk and cream before adding them to the eggs and pumpkin, so the fat is spread evenly.
4. Bake to the right point. Pumpkin pie is done when the center reads about 175°F and still jiggles slightly. Cool it, then refrigerate within 2 hours.

Holiday uses and mistakes to avoid

Half and half shows up all over the holiday table: pumpkin and sweet potato pies, Christmas morning breakfast casseroles, creamy mashed potatoes, homemade eggnog-style custards flavored with vanilla and nutmeg, and bread pudding. Any of the milk and cream mixes work in all of these. Evaporated milk is a classic in pies. Milk plus butter is great in mashed potatoes, where a little extra butter only helps.

Common mistakes

• Using fat-free half and half in custard. It's skim milk with thickeners and sweeteners added, and it can bake up loose or gummy. Stick with real milk and cream.
• Boiling a sauce after adding the swap. Lower-fat mixes curdle more easily. Add them near the end and keep the heat at a gentle simmer.
• Swapping in sweetened condensed milk. It's far too sweet and thick. Evaporated milk is the one you want.
• Undercooking egg dishes. Breakfast casseroles and quiche need to reach 160°F in the center. Custard pies should be chilled within 2 hours and eaten within 3 to 4 days.
• Using half and half to whip. It won't hold peaks. See our guide on how to make whipped cream for what does.

Questions people ask

How do I make half and half from milk and cream?

Mix 1/2 cup whole milk with 1/2 cup heavy cream for 1 cup. That runs a bit richer than store-bought, which most recipes like. For a closer match, use 3/4 cup whole milk and 1/4 cup heavy cream. Stir well before using, and keep it in the fridge for as long as the earliest date on your milk or cream.

Can I use milk instead of half and half?

Yes, in most baking. Whole milk works cup for cup in muffins, pancakes, quick breads and cakes, with a slightly less tender crumb. In custards, cheesecake and pumpkin pie, plain milk can bake up thinner and less silky, so add a little cream or melted butter, or use evaporated milk instead.

Can I use heavy cream instead of half and half?

You can, but it is about three times richer. Thin it down for a closer match: mix 1/4 cup heavy cream with 3/4 cup milk, or use 1/2 cup heavy cream with 1/2 cup water if you have no milk at all. Straight heavy cream works in a pinch but makes custards and sauces very rich.

What is a good dairy-free half and half substitute?

Mix 1/2 cup full-fat canned coconut milk with 1/2 cup unsweetened oat, soy or almond milk. It lands near half and half in richness and works in baking, soups and coffee. Soy milk alone is the next best pick for baking. For coffee, thicker barista-style oat milks taste closest.

Is evaporated milk a good substitute for half and half?

It is one of the best for pies and custards. Use it cup for cup. Whole evaporated milk has a bit less fat than half and half but more milk protein, so it sets custards well. It adds a faint caramel note that suits pumpkin pie. Do not use sweetened condensed milk, which is much too sweet.

Why did my milk and butter mix separate?

Butter and milk do not stay blended on their own, because they lack the natural emulsifiers that keep cream smooth. As the mix cools, the fat floats up. It is fine in cooked sauces, soups and batters where you stir and heat it. For coffee or cold recipes, a milk and cream mix works much better.

How long does homemade half and half last?

A milk and cream mix keeps as long as the earliest date on the milk or cream you used, as long as it stays cold in a covered jar. Shake or stir before each use, since the cream can rise to the top. The milk and butter version is best made fresh, right before you add it to a cooked recipe.
