How to make homemade dulce de leche

For this cake you can use purchased dulce de leche, or you can make your own. To make your own pour sweetened condensed milk into a glass baking dish and cover tightly with foil. Place the baking dish inside another larger baking dish. Fill the pan with water to reach halfway up the sides of the smaller pan.

Bake for about 2 hours, stirring once or twice, until the milk is a deep caramel color. Carefully remove the dish from the water bath and remove the foil. Transfer the caramelized milk to a bowl and whisk until smooth. Let it cool to room temperature before using, or store in the fridge to use later.
