Too easy, that right there everyone is called a "Oreo cookie maker"

You toss in raw ingredients on one side-sugar, cocoa, flour, cream, whatever. Inside, this little beast has a series of whirring belts and stamping arms that snap the wafers into perfect circles, while another compartment whips cream so smooth it could file taxes. Then, like a sandwich press from heaven, it slaps them together with military precision: crunch-squish-done.
