Peanut Butter Fudge -Amy

1 can evaporated milk
4 1/2 cups sugar
1 (12 oz.) package peanut butter chips
1/2 cup chunky peanut butter
1 cup butter

In a large saucepan bring the sugar and milk to a boil. Boil for exactly 7 minutes. Measure remaining ingredients into a separate bowl. Pour boiling mixture over the rest of the ingredients and stir until smooth. Spoon into a 9x13 pan that has been buttered on both the sides and bottom. Let cool and cut into squares. If you want to get really decadent, you can dip the squares in melted dipping chocolate (recipe on page 130).
