Line a baking sheet with parchment and set aside.
Pulse gingersnaps in a food processor until very fine crumbs form.
Stir crumbs, cream cheese, powdered sugar, molasses, vanilla, and spices until a soft dough forms.
Scoop about 1 tablespoon per truffle and roll into smooth balls. Arrange on the lined sheet.
Chill the tray until firm, 15–20 minutes.
Microwave white chocolate with coconut oil in 20–30 second bursts, stirring until glossy and smooth.
Dip each chilled ball in the coating, let excess drip, and return to the sheet.
Sprinkle with gingersnap crumbs and chill again until set, about 10 minutes.
