Fluffernutter!

Take the flavor of a classic Fluffernutter sandwich—peanut butter and Marshmallow Fluff on white bread— and turn it into a shake, suggests Michelle Lettrich of Browneyedbaker.com. Simply blend a few crushed peanut butter cookies (such as Nutter Butters), 2 Tbs. peanut butter and 2 Tbs. Marshmallow Fluff into a vanilla shake. Garnish with whipped cream and a peanut butter cookie.
