I made this cake for my Niece's 10th Birthday. She is a HUGE Harry Potter fan and asked for a cake that her figures could put put on. It was a lot of work, but I am fairly happy with how it turned out. The RKT roof on the main room started melting a little, but what can you do? I used 8" square and 6" square pans and carved them to the shape. Roof on both are RKT. All edible but a few skewers (and figures of course!)
