I did a Princess themed birthday cake for another cousin's daughter around the beginning of March. I had gone to the toy store and found some Princess tiara's, jewelry, etc... .that I thought was adorable. I decided to make the cake in the shape of a pillow, and then sit the jewelry, etc... on top of it.
I first baked two 12" square cakes, then leveled, torted and filled them. Then used a bread knife to shape the cake into something close to pillow shaped, lol.
The birthday girl loves bright pinks and purples and "girly colors." So, I frosted the cake in hot pink buttercream. Then decided to put some ruffles on it, like a pillow. I also had purchased sparkly piping gel and used that to decorate the top as well.
Once I got to the party, I placed the Princess jewelry onto the cake, then put the candles in and lit the candles. I thought that leaving the piping gel to dry overnight would dry it enough that it wouldn't stick to the plastic toys. I was wrong! It was a whole lot of fun cleaning the piping gel off of the jewelry and tiara, lol!
