How to Sign "Cookies"
To sign 'cookies', start by holding your non-dominant hand flat in front of you with the palm facing up, acting as a baking sheet or rolled-out dough. Form your dominant hand into a loose 'C' shape, as if you are holding a round cookie cutter. Bring your dominant hand down to tap the palm of your non-dominant hand, twist your wrist slightly, and tap it again. The motion should look exactly like you are cutting shapes out of dough.
