I made this Castle Birthday Cake for my granddaughter's 4th birthday.
These cakes are iced first with buttercream icing. Then I rolled fondant out to the right height and width of each tier. I used the back side of a long knife to "etch" in the "stone work". Then just wrapped the fondant around the cake. I used the paste icing coloring mixed with a small amount of water to "paint" the purple color on. I used fondant with a toothpick inserted to make the battlements(or crenelations). I let them dry and painted them with the same paint and inserted them into the cake. Then I just decorated the doors and added vines and flowers.
I used the Wilton premade towers but wish I had just used ice cream cones, as I have on another cake (one regular cone with a waffle cone on top upside down, then iced and sprinkled). I did use fondant on the tower roofs, wetted very slightly and sprinkled with purple colored sugar.
I also cheated on the cake, we didn't need that much and I didn't have a pan that small, so the top is actually a plastic tub from store bought icing, just wrapped in fondant (icing applied to the backside to make it stick). I added the figurines that she wanted on the cake.
The Castle Birthday Cake was constructed out of three 9-inch square layers for the base and 3 6-inch round layers for the upper structure, all filled and frosted with white whipped frosting. The square brick perimeters of the castle were made with sugar cubes. After I got the basic cake assembled, I put it in the fridge to chill while I worked on the towers.
The perimeter towers are constructed out of two cake-type ice cream cups, "glued" together at the small end with frosting and then decorated. For the peaks I iced five sugar cones and then sprinkled them with pink decorating sugar. After this had set for awhile, I placed them into the top "cup" portion of the tower. The flags are made out of purple metallic craft paper. I also slightly trimmed the back side of the towers to ensure that they would sit flush against the corners of the cake.
The top tower was decorated the same way as the outer towers, but constructed out of only one upside-down cake cup with a sugar cone placed on top.
After "gluing" all of the towers in place with icing, I hand-piped the vines, pink flowers, purple heart "window" and the purple door.
All together, this cake took about 20 hours for both baking and assembly time.
This little girls homemade castle birthday cake was made with two hexagonal cakes placed on top of each other. The cake board was also iced with white frosting for a nice and neater finish. The frosting was butter icing and was left a natural butter icing color.
Ice cream cones with sweets (smarties) were used as castle towers. The sweets were attached with icing and the cones were finished off with a fringe made out of pink plastic icing. The doors were cut out of pink plastic icing and after being placed on the cake, piping was added to finish it off neatly.
The 'Happy birthday' was actually candles and gave quite a lovely effect. More candles were added at the back of the cake, these were sparkler candles and looked absolutely gorgeous when lit! Little toys (the pony and bunny) were added to fill up spaces. More ball sweets were used for added details to the walls and to create a paving on the outside of the castle (jelly sweets were used).
The cake was also decorated at the back so that it looked just as good at the back as it did at the front! The little 4 year old loved this homemade castle birthday cake!
