Peppermint Crunch Buttercream Marshmallow Brownies

"Peppermint Crunch Buttercream Marshmallow Brownies…where have you been all my life? OK, OK…maybe you haven’t been around, because you haven’t been invented yet, until now! This has insane layers of the really good stuff, like rich, lush chocolate-y brownies, bursting with Ghiradelli Limited Edition Chocolate Peppermint Baking Chunks, fluffy, gooey marshmallow, melty chunks of Ghirardelli Christmas Limited Edition Peppermint Bark Squares, and lastly, a heavenly layer of cream cheese buttercream frosting with random sprinkles of crushed peppermint. Uhh…yea…layers of really good stuff!! OMGosh!"
