How to Make Dulce de Leche


Dulce de leche recipes vary slightly from one country to another. It’s always based on milk and sugar, but different regions have their own take.

Puerto Rico makes it with unsweetened coconut milk.

Uruguay only uses milk and sugar, no vanilla.

In Argentina, dulce de leche is made from four ingredients; milk, sugar, vanilla bean, and baking soda.

The ingredients and their measurements are provided below:

  • 4 cups of milk
  • 1 1/2 cups sugar
  • 1 vanilla bean, split and the seeds scraped
  • 1/2 teaspoon baking soda


The classic Argentina Recipe steps go as follows:

  1. Combine the milk, sugar, and vanilla bean in a large saucepan over medium heat.
  2. Bring to a simmer, occasionally stirring until the sugar has dissolved. Be sure to stir the mixture, or it will burn on the bottom of the pot.
  3. Stir in the baking soda.
  4. Reduce heat to low and let simmer for 1 hour, stirring occasionally.
  5. Remove the vanilla bean and let simmer for another 1 1/2 to 2 hours, again stirring occasionally.
  6. When done, the dulce de leche will be a dark caramel color. And the remaining could be about a cup’s worth.
