Reese Peanut Butter Cups recipe

1 box confectioners' sugar
1 cup creamy peanut butter
1/2 cup (1 stick) butter
2 tablespoons water
1/4 pound paraffin
2 (16 ounce) bars sweet chocolate

Mix confectioners' sugar, peanut butter, and butter with enough water to hold together. Form into half dollar-size patties. Melt paraffin and chocolate bars. Place a spoonful into each of 60 tiny muffin cups, then put a peanut butter patty in, then pour enough chocolate over to cover the patty and go down the sides. Chill until firm.
