This is soooo good! I got this recipe from an Ice Cream Recipe Exchange site. Find the original at http://frozentreats.blogspot.com/2008/09/dulce-de-leche.html. I initially made it for Dulce de leche Ice Cream, but I cooked the left over part into candy. I didn't have any whole milk, so I subbed 2% and half and half and I used 1 tsp pure vanilla extract instead of the vanilla bean. My husband loved the texture and taste! Haven't made the ice cream yet, but this is the best Dulce de leche I've ever had! Cook time varies depending on desired consistency.
