I like to keep a jar of this in the fridge for an ice cream topping or to make snack time a little more sweet and special. It fits perfectly between my homemade marshmallow fluff and chocolate syrup.
1 cup brown sugar
1/2 cup light corn syrup
3 Tablespoons butter
Pinch of salt
1 cup creamy peanut butter
1/2 cup evaporated milk (here's a substitute if you're out)
Combine all ingredients except the peanut butter and evaporated milk. Microwave for four minutes, stirring twice (or bring to a boil on the stove, stirring frequently). Add peanut butter and stir until smooth. Add in milk. Keep refrigerated. Reheat to serve over ice cream if desired.
