I actually got the idea for this cake by searching for ideas online. I liked the Mario cake made by Su-Yin which I found at Cooking Is My Passion. I am not nearly that good at cake decorating so here is my poor attempt at my own version.
It's a chocolate mud cake with vile green fondant icing. I made the mushrooms, stars and plants out of fondant too. The eyes are a bit silly and wrong but I couldn't change them once they were done without ruining the rest of the cake. The Mario is a plastic figure. I did actually consider making a Mario out of fondant too, but I didn't think that I was that clever. I'm quite happy with it and my son was speechless (in a good way, I think) It's the first time I've covered a cake with fondant so I was quite happy with how it turned out.
And last but not least, it's green and it's Super Mario, so all boxes, ticked.
