My son is head over heels for Mario, so for his birthday a week ago, we got him a few games and I made him a cake. It's not perfect, but you never would have known from the shrieks he and his brother let out when they saw it!
It was just a regular sheet cake, one layer chocolate, one layer yellow cake, then decorated with buttercream and buttercream fondant.
(please excuse the mess, I took some of these before cleaning my disastrous kitchen . .. which actually my husband later cleaned for me AND did dishes!)
And the excited birthday boy who told me, "Thank you for making this AWESOME cake, mama!"
