I make a video cake for my husband every year, and this is the one for 2012. It's Minecraft! The figures are made with gumpaste, then handpainted with icing color.
I tried to make the cake as blocky as I could and covered each side separately. It's also made with 3 types of cakes: gluten-free yellow cake, normal yellow cake, and chocolate cake. There's a peppermint frosting underneath the fondant.
