You’ll need just two ingredients: heavy cream and milk. The ratio is embarrassingly simple. For one cup of half-and-half, combine ½ cup heavy cream with ½ cup milk. That’s it. No magic spell required.
If you’re a “guesstimater” like me, you can pour a splash of cream into a measuring cup, then top it off with milk. But don’t be that person who eyeballs too much cream—you’ll end up with ultra-rich half-and-half that’s closer to single cream. Which, hey, maybe that’s your vibe. I’m not here to judge your fat content preferences.
What If You Want It Thicker?
For a slightly richer version (great for scones or pasta sauces), go with one part heavy cream, one part milk is the standard, but you can push it to ¾ cup cream + ¼ cup milk if you’re feeling rebellious. Just know that your coffee might get a tiny, delicious mouthfeel upgrade.
And if you’re out of milk entirely? You can use water. Yes, I said it. Water and heavy cream create a makeshift half-and-half that’s thinner, but it works in a pinch for baking. Please don’t try this in your coffee unless you enjoy existential dread with your caffeine.
