I "borrowed" the idea of butterscotch bars with dried mango from a Filipino snack with the same name. The package says it's from Iloilo; they're very good, somewhat chewy, and not overly sweet too. I adapted the Butterscotch Bars recipe from Betty Crocker cookbook using only half cup of sugar instead of one whole and substituting chopped dried mangoes for the nuts. I love these copycat bars. Delicious!
