I made this cake for my son's sixth birthday, at his request - he loves the Lego Batman game on the Wii. I used MMF to cover the cake and the legos (rice crispy treats), bit it was too soft for Batman and Robin - they kept collapsing and their edges were all squishy. I had to buy a package of Wilton's rolled fondant at the last minute and sculpt them out of that. Next time I'll just make the figures out of gumpaste!
