Cream shortening and peanut butter. Gradually add sugar and brown sugar. Cream well. Add egg, milk and vanilla. Blend in dry ingredients. Mix well. Shape in balls. Roll in the extra white sugar. Bake as a cookie “ball” (dont press down on them…yet) on ungreased cookie sheet for 9 minutes. Start unwrapping the hershey kisses while the cookie balls are baking. Remove the cookie balls from oven and place a kiss (the chocolate kind of kiss ) on each cookie ball and press down until edge of cookie cracks around the edge a bit. Return to oven and bake an additional 3 minutes.
