Preheat oven to 375 degrees. Mix together butter and peanut butter. When blended, add white and brown sugar, mix again, then add egg, milk and vanilla, then mix again. Gently stir in flour mixed with baking soda and salt. Chill the dough for about an hour, then roll dough into grape-sized balls, roll in granulated sugar and place on ungreased (or Silpat-lined) cookie sheets. Bake about 8 minutes, until lightly browned. Place a mini-kiss in the center of the cookies right away, pressing gently. The cookies will crack, that’s fine. emove from pan, let cool.
