Directions

1. In a small mixing bowl, stir together flour, baking soda and baking powder. Set aside. In a larger bowl (we used an automatic mixer bowl), mix together butter and sugar until smooth. Add in egg and vanilla and continue to mix. Slowly, add dry ingredients.
   
2. On an ungreased cookie pan, spoon dough into ping pong ball-sized balls (we use a cookie scoop). Using the back of a spoon, gently flatten out each ball (not all the way). Add sprinkles, if desired.
3. Bake for 8 minutes at 350 degrees. Let cool for 1 minute and then cool completely on cookie rack.
   
4. For the icing: In a small mixing bowl, combine cream cheese, powdered sugar and butter. Then, take a generous spoonful and spread on one cookie. Top with another cookie (should look like a sandwich).
   
5. Serve immediately, or store in air-tight container.
