1 Box Cake Mix - any flavor (Devils Food, White, Spice are fabulous)
1/2 Can Sweetened Condensed Milk
1 Egg

Dump it all in a bowl and mix with a fork. It should be the consistency of cookie dough, if it's too dry, add a little more Sweetened Condensed Milk, or a little flour if it's too wet.

Roll into a ball (golf ball size) and roll in sugar, bake 350 for 10-12 minutes. I have found these are best baked on a baking stone if you have it.

Great mix ins:
Devils Food - chocolate chips, reeses pieces, peanut butter chips
White- Chocolate chips
Spice - butterscotch chips

Great recipe when you have a craving for cookies but don't have all the ingredients!
