Preheat oven to 350°. Combine flour, baking soda and salt; set aside. Cream together remaining ingredients; add dry ingredients and mix until blended. Roll into 1-inch balls and roll in 2 tablespoons of granulated sugar. Bake on ungreased cookie sheet for 7 to 8 minutes. The cookies just start to turn brown and crack. Remove from oven and press a chocolate kiss or peanut butter cup into center. Set on paper towels until cool and the candy is hard again.
