Grandpa s Peanut Butter Fudge

2 cups brown sugar

2 cups white sugar

1 cup milk

1 ½ cups creamy peanut butter

1 tablespoon margarine

1 ¼ teaspoons vanilla extract

Mix brown and white sugar with the milk in large pot; bring mixture to a boil. Stir in peanut butter, reduce heat to medium, and bring the mixture back to boil (stirring constantly). Remove the pot from heat when a drop of the mixture forms a ball in a glass of cold water.

Stir margarine and vanilla into the mixture; stir vigorously until the fudge hardens. (Always stir in same direction.) Pour fudge onto buttered plates or waxed paper. Let cool and cut into 1-inch pieces.
