Rich and creamy butterscotch sauce

This luxurious sauce, which features brown sugar, half-and-half, corn syrup, butter, apple cider vinegar, and a touch of vanilla extract, and requires just one saucepan to make, is delicious over baked apples or pears, but it also makes a fabulous butterscotch sundae. Here's how to do it: Simply place a couple of scoops of frozen vanilla-flavored yogurt in a dish and top with a dollop of fat-free whipped topping. Drizzle with 2 tablespoons butterscotch sauce and garnish with a sprinkling of chopped toasted hazelnuts. You can refrigerate the sauce for up to one week, so you can have some on hand for however you'd like to use it.
