For my daughter's 4th birthday, I made a princess castle cake to go along with her princess themed party. I got a few ideas from other pic's and put together my favorite parts to make this cake.
I used 2.5 cakes made in square pans (two full ones and one cut into fours that I used two pieces from.
I put the bottom two together to make the bottom of the castle and then stacked the smaller squares in the center (all bound by icing in between). I used buttercream icing for all of the cake, homemade from a recipe I use. Once it was all iced, I made the sides by taking two ice cream cones and 'glueing' them together with chocolate with an sugar cone 'glued' on top to be the top.
I cut the tip of the sugar cones off so that the candles could fit in just a bit. The sugar cones were iced and rolled in sprinkles, while the normal cones were sprayed with Wilton decorator spray, making it much faster and easier. The middle part of the castle was made with one ice cream cone and one sugar cone - giving it just enough lift.
The walkway was 'jr mints pastels', the buttons on the castle were a candy I found at the dollar tree, and the door of course was a graham cracker. The figures I also found at dollar tree, and they worked out great!
I really looked through this site and took a little bit from a lot of people to create my own Princess castle cake. The recipe I used from allrecipes.com called the Heavenly White Cake (a wonderful cake recipe).
For the frosting I used a basic buttercream frosting only without butter. I also added a half teaspoon of almond extract to compliment the cake. I used a 9 inch square for the bottom, 6 inch round for the top and one regular cupcake for the very top.
For the windows I cut pieces of fruit roll up and outlined with twizzlers ropes. I also used this for the drawbridge. The door was a graham cracker. I used edible Easter grass and caramel rounds for the pathway. The turrets are ice cream cones that I painted with corn syrup and rolled in red sugar crystals or shook in a bag of red sugar.
I used dots around the bottom layer and yogurt pretzels on the top layer. I used tootsie rolls for the draw bridge, and a candy jewel ring over the door. I used skewer sticks to hold the the ice cream cones to the cake. It turned out great especially for the first time making it!
For my daughters 7th birthday I wanted her to have a Princess Castle Cake. She has been a princess from the day she was born. The pink was very specific. In our house it's called Shau'Rae pink. We used the neon food colors to get it just right.
The towers, windows and door are from the castle kit by Wilton you can purchase almost anywhere that sells cake supplies. The cake it's self is two nine inch rounds and two extra thick six inch rounds, using strawberry jam as filling.
Tips used (sorry I don't have the numbers right off) were the medium star, the small and medium standard writing and the small leaf. I had my husband drill small holes in the top of the plastic tower toppers for the candles to stick into.
Total decorating time was 4.5 hours. Her face when she saw it was well worth every minute!
