Birthday Cake - number and heart M&M's, Kit Kats, Whoppers

This cake is simple and easy to make, but has a big wow factor.  I like that.  All you do is make a two-layer cake and frost it (both layers are upside down so that the top is flat).  Lay down a row of Whoppers.  Press on Kit Kat sections (use a knife to cut the sections apart--you'll have neater edges).  This cake used nine Kit Kat bars.  We like how they look like exclamation points, but I don't sweat making sure the Whoppers and Kit Kat sections line up.  Then create the number and heart, and then the outlines, all in M&Ms.  And there you have it!
