Preheat oven to 350.

In your electric mixer's bowl, beat the shortening and peanut butter on medium to high speed for 30 seconds, or until well combined.

Add the granulated sugar, brown sugar, baking powder and baking soda.

Beat until well combined and"fluffy", occasionally scraping the sides of the bowl.

Beat in egg, milk and vanilla until well combined.

Beat in the flour.

You may stir in any remaining flour with a wooden spoon if your mixer doesn't get it all.

Shape cookie dough into one inch balls.

Roll the balls (individually) in the 1/4 cup granulated sugar.

Place balls 2 inches apart on an ungreased cookie sheet.

Bake for 10 to 12 minutes, until bottoms are lightly browned.

Do not overbake.

Immediately press a Hershey's Kiss into the center of each cookie.

Transfer cookies to a wire rack to cool.

After cooling, hide them from your children, or you won't get any.
