Preheat oven to 350 degrees F. In a large mixing bowl beat shortening and peanut butter with an electric mixer on medium to high speed for 30 seconds. Add the 1/2 cup granulated sugar, brown sugar, baking powder, and baking soda. Beat until combined, scraping sides of bowl occasionally. Beat in egg, milk, and vanilla until combined. Beat in as much of the flour as you can with the mixer. Stir in any remaining flour.

Shape dough into 1-inch balls. Roll balls in the 1/4 cup granulated sugar. Place 2 inches apart on an ungreased cookie sheet. Bake for 10 to 12 minutes or until edges are firm and bottoms are lightly browned. Immediately press a chocolate kiss into each cookie's center. Transfer to a wire rack and let cool. Makes 54 cookies.

Place in layers separated by waxed paper in an airtight container; cover. Store at room temperature for up to 3 days or freeze for up to 3 months.
