I sat near a girl at work who loved M&Ms. So, just for fun, I made her this birthday cake.
It's 2 8" rounds of chocolate cake and one 12" round. Layered - 8-12-8 with chocolate frosting between the layers. Then I carved it into the shape of an M&M candy, covered that with frosting, and then wrapped the whole thing in fondant that I'd tinted green. Then I iced the "m" on the top with royal icing and surrounded the whole thing with mini M&Ms.
