I didn't take step-by-step pictures of this cake. I started putting it together after getting up from a nap so I was a bit fussy. But as I was making it, I became more cheerful. Note to self: don't decorate cakes right after a nap, take some time to wake up. =)
I frosted the cake pink and then added fondant "brick" panels. Some of the bricks didn't match up, but it worked because most castles have cracks and imperfections. The tops of the towers are sugar cones covered in fondant and then painted with pink pearl dust. The front of the castle has a brown fondant door, purple fondant flowers and green grass/vines piped on.
This was my first castle cake. I loved how it turned out. It's fit for a queen!
