Grease a small pan and add the chocolate chips to the bottom.
Sprinkle the crushed chocolate chip cookies evenly over the chocolate.
Top with plain mini marshmallows, then finish with red and green sprinkles.
Grill at medium-low heat with the lid closed for 6 to 9 minutes, until the chocolate is melted and the marshmallows are puffed and lightly golden. Serve warm with extra cookies for dipping.
