CRAVE Bar - M&M Cookie/Oreos/Brownie/Frosting

A special layered treat: M&M cookie base, a layer of Oreos, and brownie on top, with vanilla buttercream frosting and holiday sprinkles. This treat weighs in at nearly 3/4 lb!
**NOTE: these will NOT have a lid. The frosting is piled too high for the lids to fit properly.**
