I usually do two versions of butter cookies

1) softer dough for using in the cookie press
2) less soft dough (more flour, sugar and egg but the same amount of butter as the previous) for cuttouts decorated with royal icing

Also chocolate chip cookies with chips & M&Ms, macaroons & White Trash (yes, terribly Un-PC but its been called that for as long as I can remember).

White Trash
Corn & Rice Chex (or Crispix)
Cheerios
M&Ms
Peanuts
Mini Pretzels

Coat it all in melted white chocolate chips and spread out over wax paper to harden. Break up the larger bits and enjoy!!

There's a newer recipe out there similar to this called "Puppy Chow" that involves peanut butter and milk chocolate to coat.
