I am no stranger to stamping on food. I include some projects and how-tos for stamping on royal icing and fondant to top cookies, cupcakes and cakes in my book (um, Sugarlicious, for those that haven’t bought it yet, go ahead, I’ll wait…). But I avoided marshmallows because their squishy surface isn’t ideal for stamping. But if you are careful, you can do it pretty easily. Find the how-tos HERE at the decorated cookie.
