Dulce de Leche

1. Step 1

   Combine sweetened condensed milk and corn syrup in a large (2 to 2½ quart) microwave safe bowl.

2. Step 2

   Microwave on 50% power, stopping and stirring every 2 minutes initially then more frequently as needed during the middle of the cooking time for a total of 10 to 12 minutes or until the mixture is thick and caramel colored. It is important to watch the mixture as it cooks and stir frequently to avoid boil over. The mixture develops a somewhat curdled appearance that will smooth out when stirred. Whisk in butter and set aside.
