The cake was decorated using fondant, even the characters around the cake were made from fondant. I made Piranha Plants, Goomba's, Mushrooms & Koopa Troopa shells. The cake was finished off with figurines, which also make a great present for the birthday boy/girl to keep afterwards.
The same cake and frosting recipes that was used to make the Lego cake, were used to make this cake too. I used one quantity of the cake recipe but divided it between a 6" tin & 8" tin to make the two layers. Here is a picture of the inside of the cake.
Tip: if you want more height for your cake, just cut each of the two layers in half. Then ice and sandwich each of the 2 layers together (i.e. total of 4 separate pieces, 2 for the 6" cake and 2 for the 8" cake). I added an extra 1 cup of evaporated milk to 1 quantity of the frosting and found that it was enough to cover both layers with a bit extra to spare.
It was such a fun cake to make and all the kids absolutely loved it... so mummies (and daddies) give it a go and surprise your little one with this special cake for their next birthday! :)
PPS: Figurines were purchased from Anime at Abbotsford in a pack for $20.
