Peanut Butter Sundae Sauce - cooking recipe

Ingredients

1 (14 ounce) can sweetened condensed milk (NOT evaporated milk, I use fat-free with good results)
1/3 cup peanut butter (I use smooth, but chunky is fine if you prefer)
1/3 cup chopped peanuts (optional)
1 teaspoon vanilla extract
1/2 teaspoon ground cinnamon (optional)

Preparation

Combine sweetened condensed milk and peanut butter in a heavy saucepan. Cook over low heat, stirring often, until thickened.
Remove from heat. Stir in vanilla and optional peanuts and cinnamon (if using).
Refrigerate leftovers.
May be used as a dip for sliced apples, too.
