What is dulce de leche?
Dulce de leche is whole milk and sugar, cooked over low heat for hours until the milk itself browns and thickens. The name is Spanish for “sweet made of milk,” which is a fairly literal description of what happens in the pot.
Say it: DOOL·seh deh LEH·cheh
Where it comes from
People have been making it across South America for about two hundred years. In Argentina, Uruguay, Paraguay and Brazil (where it is called doce de leite) it is not a specialty item. It is a cupboard staple, roughly as ordinary as peanut butter is in an American kitchen, and it turns up on breakfast bread, inside cookies, over ice cream and in most birthday cakes.
Every one of those countries will tell you it invented the stuff. That argument is not getting settled here.
How it is made
The ingredient list is short: whole milk, sugar, low heat and a lot of stirring. Over a few hours the milk browns and thickens on its own. That browning is the Maillard reaction, the same thing that happens to bread crust and seared steak, and it is where the toasted-milk flavor comes from.
This is the part that separates it from caramel. The color and the flavor come from the milk, not from burnt sugar.
What it tastes like
Toasted milk and brown sugar, with a slightly salty edge at the finish. It is thicker than caramel sauce and much less sharp. On a knife it holds its shape. On warm bread it goes soft immediately, which is the entire reason bread is the first thing anyone does with it.
How to eat it
- On bread. Plain white bread, thick layer, around five in the afternoon. In Paraguay that small meal has its own name: la merienda.
- In coffee. A spoonful instead of sugar. It sweetens and creams the cup in one move.
- Over ice cream. Warm it fifteen seconds first so it pours. Also crepes, also flan.
- In baking. Cookie fillings, which is what alfajores are, plus cheesecake, cake layers and banoffee pie.
So is it just caramel?
No. Caramel is sugar cooked until it burns. This is milk cooked until it turns. The whole argument is on one page: is dulce de leche just caramel?
Questions people actually ask
Is dulce de leche the same as caramel?
No. Caramel is sugar cooked until it burns. Dulce de leche is whole milk and sugar cooked together over low heat until the milk itself browns. It tastes of toasted milk and brown sugar rather than scorched sugar, and it is thicker.
How do you pronounce dulce de leche?
DOOL·seh deh LEH·cheh. It's Spanish for “sweet made of milk.”
Is dulce de leche the same as cajeta?
They're close cousins. Cajeta is the Mexican version, traditionally made with goat's milk. Dulce de leche, the South American original, is made with cow's milk.
Is dulce de leche gluten free?
Traditionally yes. The base ingredients are milk and sugar. Always check the label of whichever brand you buy. Dulkitta is gluten free.

Unopened it lives in the cupboard. Once opened, refrigerate it and finish the jar within about 30 days.
