I love love love simple recipes!
1/2 cup milk
2 cups granulated sugar
3/4 cup Jif
1 tsp. vanilla
In medium pan mix milk and sugar. Heat on medium heat until it boils. Boil until it reaches soft ball candy stage or just over two minutes. Stir the whole time. Take off burner and add peanut butter and vanilla. Stir and put in desired pan. The thicher the better. I suggest using a small glass baking dish.
