NotesTranslated from Spanish as “Sweet Milk,” Dulce de Leche is essentially a ridiculously intense caramel-flavored sauce made from sweetened milk. Unlike true caramel which is made by boiling sugar, dulce de leche is made by slowly simmering milk until it thickens and turns golden in color. These days it is possible to buy pre-made dulce de leche filling but if you’ve never had it freshly made you have been seriously missing out something special.
When I made this batch, I had to force myself to stop eating it by the spoonful while it was cooling because it was so darned tasty! Homemade dulce may be fantastically flavorful, but it does come at a price. The filling needs to simmer for 3-4 hours before it is ready to use so you definitely have to ready to invest a little time to make this treat. But if you take the time, you won’t be sorry. Dulce de leche can be used for much more than filling a cake. It can also be used to make brownies, fruit crisps and cheesecakes.
