Found this recipe floating around the internet in several forums; haven't tried yet, but will soon. The notes the author put up were as follows:
"This mixture is useful in any recipe where you'd ordinarily use sweetened condensed milk (like Eagle Brand.) Using the Diabetisweet adds less than 1 carb per serving but aids in proper consistency, however, it will still be delicious without it. Depending on your plans to use it, adding a bit of vanilla after cooking can be a nice touch."
Says the optional DiabetiSweet can be added at 2 Tbsp
