So how do you create a Cinderella birthday cake? I'm so glad you asked! First bake a cake in a bowl....glassware is best. It'll take about twice as long to bake. Then turn it upside down onto your platter to look something like this:

So then you cheat and buy frosting. But since this is a Cinderella cake, you need to add about half a jar of blue food coloring to the frosting. Then throw the frosting in the fridge to let it thicken up a bit. While that's happening, steal a Barbie doll from your daughter (while she's sleeping, and preferably one she doesn't play with too much) and pull the top off. Cut one leg off the bottom half and cut the top third of it off. Wrap it with saran wrap and use it as a pick to support the top half. Grab a baby rubberband and two clips and create a cute little up-do for the doll. Stick this lovely creation into the cake. Voila! You have a princess cake base! (or for those so inclined, go to Michael's and buy the doll cake-pick) Now pull the slightly cooler, very blue frosting out of the fridge and frost the base of the cake. Then fill a decorator bag with blue frosting, add a star tip, and start adding detail! This will be the result:

Then realize that it is so humid that the frosting is melting and starting to slide. Put the WHOLE thing in the fridge and leave it there overnight!!!!! Then wake up before the birthday girl to finish the details. Oh yes, but before you go to bed, take another can of frosting and add about a half pound of powdered sugar to it -- but no food coloring this time. Put this in the fridge as well!!! Then you can go to bed. Now in the morning, pull the whole thing out and fill another decorator bag with white frosting and a star tip. Add your fields of color and some stars and other details. You'll get something like this once you add some large white sugar crystals to the base:
Finish off the bottom of the cake with an extra border of blue.
Lastly, don't forget that some of your little one's friends might not want Cinderella cake, so make a batch of cupcakes to go with it all!
....you have now successfully created a Cinderella party cake!! (and Mom, Grandma, and Carol will be proud of you!)
