This princess castle cake was a blast to make! I made it for my niece's 2nd birthday party. It did require a lot of time, but some steps can be done a few days in advance of baking and assembling the cake.
I purchased the Wilton Castle Kit that comes with the plastic pillars, windows and doors. Each of these pieces you can decorate and set aside days before assembling the cake.
The cake itself is just a two tier round cake. I tinted my icing purple and iced each piece of the pillar tops and roof. Before the icing dried, I sprinkled regular raw sugar that I also tinted purple (very easy to do and it added the sparkle effect that every princess castle should have). I also decorated all of the plastic parts with the window detail, door detail, etc. and let them sit overnight so that the icing would set.
I cut dowels rods to the length I needed to attach to the bottom of the plastic pillars. I attached them with melted sugar as it was cooling. Dunk the bottom of the rod in the melted sugar and hold into place on the bottom of the pillar for a few seconds.
Once the tiers of the cake were assembled, I used a small flower piping tip to place the pink flowers around the top and base of each cake. I added a small white dot in each flower center and some green for leaves. Then I placed each pillar into the cake with the dowel rods I had already attached. The pillar cone tops went on next. Just used icing to hold them in place. Then each pillar that went around the cake on the base was last. I used icing to hold these in place too.
The small cake on the side was the birthday girl's piece! I got the Tierra at Wal-mart for pretty cheap and bought enough for all the other girls at the party to wear! They were a big hit!
I would make this one again! I had so much fun putting this one together. I am not sure if it would travel well, one thing to think about. Once it is made, I would not try to move it!
