Oh I love those princess cakes!
Here is the cake I did last year for DS's 2nd birthday.
Not super awesome but also not bad for my first try

I was pretty darn proud of that thing and was also up until 3am making it!
I will be doing Mickey Mouse this year...paid $50 for the cake pan! Luckily my friend's mom is a Disney fanatic too and he said he would buy it from me to give to her when I am done with it.
I am trying to come up with something neat to do for the cupcakes but I can't find anything Mickey anywhere. I found a couple cute ideas in a Wilton cupcake magazine. So we shall see. I know that I am itching to bake a cake though!
