For the cake itself I baked an entire cake mix in a 9" Pyrex bowl. It took close to an hour to bake. Then I made 3- 9" round cakes. All together it took about 2 1/2 cake mixes. Cut circles in the middle of all the cakes, stack layers with frosting in between, wrap Barbie in plastic wrap then drop her down into the center. Pretty easy and much cheaper than those princess cake pans you buy at a craft store
Start by making your own butter cream frosting. Here's the recipe I used:
In a mixer combine -
1 cup butter
1 pound powdered sugar (add just a little at a time)
1 teaspoon vanilla
a couple teaspoons water (or milk) until you reach the desired consistency
I needed about 4X the recipe for this cake.
Smooth frosting out the best you can. I used upward strokes with a spatula.
Now refrigerate until it's crusted over. About 10-15 minutes.
Place a paper towel onto the frosting and smooth your hands over it. You can feel the lumps and gently apply just a little extra pressure to those areas. Gently peel off the paper towel. It shouldn't stick too much. If it does, you either pressed too hard or didn't refrigerate it enough.
Refrigerate it again then apply your piped designs.
A perfect princess cake for your princess!
