After I did the original dulce de leche I was anxious to see if it would work with non fat sweetened condensed milk. Well, it looked it exactly the same but it surely didn’t taste exactly the same. I had one bite of it and decided that it wasn’t worth eating. It was yucky. I really was sad because I was hoping that it would work out but this is one of those times where you need to eat the full fat version. Sorry! There is a low-fat version of sweetened condensed milk that might taste better…if you try it let me know how it tastes. 1 star.
