Cyclops Cookies

For my eighth birthday, my grandparents gave me my first cookbook, Better Homes and Gardens Cookies for Kids. Twenty some-odd years later, I still turn to it to make some of my most loved cookies. Some pages are falling out, some are sticky, but whenever I flip through it, I feel like an eight year old again.
Give these peanut-buttery cookies a try. Don't you want to be a kid again?

1/2 cup butter, softened
1/2 cup creamy peanut butter (that's the only kind the cyclist will allow in the house)
1/2 cup sugar
1/2 cup brown sugar
1 egg
2 T milk
1 tsp vanilla
1 3/4 cups flour
1 tsp baking powder
1/4 tsp salt
1/8 tsp baking soda
granulated sugar
30-36 Hershey Kisses, unwrapped

In large mixer bowl, beat butter and peanut butter on medium speed about 30 seconds. Add the sugar and brown sugar and beat until fluffy. Add egg, milk and vanilla. Beat well.
In a medium mixing bowl, stir together flour, baking powder, salt and soda. With mixer on low speed, gradually add flour mixture to peanut butter mixture, beating well.
Cover and chill 1 hour (not completely necessary if you don't have the time, it just makes the dough easier to handle).
Preheat oven to 375*. Shape dough into 1-inch balls. Roll in additional sugar. Place about 2 inches apart on un-greased cookie sheets.
Bake for 10-12 minutes or until edges are firm. Immediately press a chocolate kiss atop each cookie. Cool on rack.
