This was my 2nd Mario cake. I made one just like this back in April for my little boy's birthday. This is a 10in square cake with an 8in. round on top, all butter cream icing with fondant decorations to match the Mario game. I made the topper by using a styrofoam bowl. This cake is especially cute when the little Mario figures are added. I had a lot of fun making this cake, I can't believe Mario is coming back.
