I got asked to do a Harry Potter cake. It was a little hard to come up with an idea since I haven't read any of the books or seen any of the movies in the last 5 years, so I was really hoping that what I came up with wasn't totally lame to a Harry Potter fan.
So I tried to make it look like a big, well-worn book of spells. And on of the front I tried to put something that looked like the Hogwarts crest and an edible pair of Harry's glasses. When I delivered the cake (which was a surprise for her!) she seemed to like it so that made all the effort worth it!
