These cookies are from the Blue Owl Restaurant in Kimmswick, MO. This is one of the best dessert restaurants (and regular food) I've ever been to.
You will need:
1 box lemon cake mix
2 cups Cool Whip (thawed)
Mix first 3 ingredients together. The dough will be very runny. In a separate bowl with powdered sugar, drop in about a tablespoon of dough and shake the bowl around to coat the dough ball. Remove the coated dough from the powdered sugar and place on a cookie sheet. Space cookies about 3 inches apart. Bake for about 10 minutes at 350 degrees.
