Custard Powder

Custard powder is a finely milled, starch-based powder that turns milk into a smooth, golden, vanilla-scented custard with hardly any effort. It's built mostly from cornstarch, with vanilla flavoring, a little sugar, and usually a touch of yellow coloring to give that classic sunny hue. Unlike traditional custard, which leans on eggs for its richness, custard powder thickens through starch alone — which is exactly why it's such a reliable shortcut for anyone who's ever watched an egg custard curdle at the wrong moment.

The flavor is gentle and familiar: sweet, creamy, and warmly vanilla, without the eggy note you'd get from a baked custard. Cooked properly, it sets into a velvety pour that's thick enough to coat the back of a spoon but still loose enough to flow over a warm crumble or a slice of sponge. Because it's egg-free in its dry form, it's a handy pantry staple for households cooking around egg allergies, though you'll still want milk (or a plant-based milk) to bring it to life.

Most cooks reach for it to make an everyday pouring custard, but it does far more than that. Fold it into cake batters for a softer crumb, use it as the base for a quick pastry cream, or stir it into fruit fools and trifles. As a thickening agent, it behaves much like plain cornstarch — just with vanilla and sweetness already built in.
