Cool Whip Cookies (Crinkles)

1 box any flavor cake mix (chocolate, orange, lemon, red velvet, carrot, spice, etc...)
8 oz. cool whip, thawed*
1 egg*
confectioners sugar

Mix all ingredients together except confectioners sugar. Batter will set up after a few minutes. Drop by teaspoonfuls into confectioners sugar. Place on cookie sheet. Bake at 350 degrees for 12-15 minutes. Cool. Store covered. 

*can also be made just using 1/4 c. + 1/2 T. oil and 2 eggs, instead of the cool whip. Follow the same directions as above. Either way they are yummy!
