mezzacotta Café patron Rebecca Curtis sent in this photo of an M&M smoothie.
You can't really see the little bits of M&M floating in the smoothie, so I put some on top of the whipped cream for added visual interest. This one is made with banana, vanilla ice cream, milk (rice, soy, or dairy will work), and peanut butter M&Ms in a blender; topped w/whipped cream and whole M&Ms. I could have added some peanut butter to the smoothie, but the peanut butter M&Ms took care of that. (Mmmmmmm... peanut butter banana..... Yummy!) Oh, and make sure to use an extra width straw, otherwise the M&M bits will get lodged in a regular sized one.
