This is a recipe I got from my friend Carolyn many years ago. It is easy (only 4 ingredients) but pretty cookie.
The cookies in the photo were made using a Red Velvet/Green Velvet cake mix I found at Aldi's. You can use any cake mix. I have used German Chocolate, Lemon and Strawberry. All were good.
1 cake mix (dry)
2 cups non-dairy whipped topping (Cool-Whip)
Mix together the cake mix, egg and whipped topping. The dough will be very stiff. You can chill it at this point and then roll into balls before placing in the powdered sugar but if you don't have time to chill the dough, you can just drop small spoonfuls into the powdered sugar Roll around to coat with the sugar and then place on a baking sheet. The cookies will spread some so leave about 1.5 inches between them.
Bake at 350 for 10 minutes (chewy) or 12-15 minutes (crispy). Remove from baking sheet to a cooling rack. Store in an airtight container.
