1 stick butter, softened
1 lg. egg
1 cake mix (this is the fun part, ANY kind of cake, can have lots of different flavored cookies)

Stir butter and egg together, add cake mix and stir to make cookie dough. (If real dry, add 1 more egg, NO LIQUID). Roll like sugar cookie dough (log style). Refrigerate for at least 2 hours so cookie dough will slice. Bake at 350 degrees on ungreased cookie sheet 6 to 8 minutes. COOKIES WILL DOUBLE IN SIZE. Can make several kinds of dough and freeze to have on hand when FAST cookies are needed.
