Does this look right? It doesn't say anything about the cookies getting crinkly, but, perhaps this is close.
Lemon Whippersnappers
1 pkg. lemon cake mix
2 C. prepared whipped topping
1 tsp. lemon flavoring
1 egg, beaten
powdered sugar
Combine all ingredients, except powdered sugar, and mix well. Shape in 1 inch balls and roll in powdered sugar. Bake on lightly greased cookie sheet for 10 min. at 350. Do not overbake. These do not brown on top, only on the bottom.
