Every Christmas, we make peanut butter Rice Crispies. Love them, since there's no cooking involved, and you get to get your hands all sticky! We also don't measure... it's pretty much the easiest recipe ever, since you really just do everything until it "feels" right, sticks together, and you can roll them into balls.
It's Rice Crispies, peanut butter, marshmallow fluff, and M&Ms. Once the ingredients are mixed and rolled into balls, wrap them in wax paper the same way you would wrap salt water taffy. You can make them as big or as small as you would like. Store in an airtight container at room temperature.
LOVE, LOVE, LOVE!!!
