Peanut Butter Kiss Cookies

Taken from www.allrecipes.com (I tweaked the recipe a bit though)

• 1/2 cup white sugar
• 1/2 cup brown sugar
  
• 1 cup peanut butter
• 1 egg
• 1 tsp vanilla
  
• 18 milk chocolate candy kisses, unwrapped

1. Preheat oven to 350 degrees F.
2. Combine sugar, peanut butter, and egg.
3. Shape into 1 inch balls and place on ungreased cookie sheet. NOTE: If dough is too sticky, refrigerate 1/2 hour or until easy to handle.
4. Bake for 10 minutes. Remove cookies from oven. Press a chocolate kiss into the center of each warm cookie.
