I used an eight inch square of chocolate cake and an eight inch of the same size vanilla cake back to back to make just the right amount for a Sabrina Little Witch birthday celebration. The house was a Wilton gingerbread house I decorated and the little witch is a Polly Pocket doll with a fondant witch hat that I added and sparkled with edible disco dust. I felt like she needed a friend so the frog was a donation from a collection of small toys my daughter won at Chuck E. Cheese. The broom was a cinnamon stick with fondant bristols painted with a bronze lustre dust. The grass is piped on with a hair Wilton tip and the pumpkins were made with the help of my daughter. I would have never finished the cake without her help because I under estimated the time I would need to get the house done drastically. Crushed Oreos with a blackberry border for the walkway which were actually jelly candies I bought at Marshalls and they worked out perfectly in the mad rush to finish. Another thing I found helpful was using poppy seeds on the roof of the house which I learned from watching, Buddy, The Cake Boss on The Learning Channel.
It is so much fun using dolls on the cakes I make for little girls, besides saving money for the person buying the cake. Like the five year old in this case she will get a doll to keep, play with and it is also a gift that can hold wonderful memories. If you can get a doll that looks like the birthday girl, even better.
