Extra Work Peanut Butter Fudge - cooking recipe

Ingredients

cooking spray
1 (12 fluid ounce) can evaporated milk
2 1/2 cups white sugar
1 cup peanut butter
1 tablespoon butter
1 teaspoon vanilla extract

Preparation

Spray a 9x9-inch pan with cooking spray.
Mix evaporated milk and sugar together in a large, heavy-bottomed pot over medium-high heat. Bring mixture to a boil, stirring constantly, until syrup reaches 234 degrees F (110 degrees C), 5 to 7 minutes. A teaspoon of hot syrup dropped into a glass of cold water should form a soft ball of candy.
Remove from heat and immediately stir in peanut butter, butter, and vanilla extract. Stir constantly until fudge is smooth and thick. Pour fudge into prepared pan. Let cool before slicing into squares.
