1Preheat oven to 350 degrees. Grease or spray cookie sheets with cooking spray. In medium bowl, combine flour, baking soda, baking powder and salt; set aside. In large bowl, thoroughly cream shortening, sugars, and vanilla. Add eggs and beat thoroughly; stir in peanut butter. Gradually beat dry ingredients into creamed mixture. Form into 1" balls and dip tops or roll in sugar; place on cookie sheet. Press each with back of a fork to make crisscross design. Bake 10-12 minutes or until golden brown. Remove from oven and cool on cookie sheets for 1 minute. Cool completely on wire rack.
2Peanut Butter Glaze: Combine peanut butter chips and shortening in microwave safe bowl. Stir at 15 second intervals until mixture is melted. Drizzle over cookies. Let set until glaze hardens.
3Note: These cookies are best when well browned.
For Giant Cookies: Roll 4 scoops into balls. Bake about 20 minutes or until well browned. I use a large cookie sheet which allows me to bake 4-6 large cookies at a time.
