I picked up some cheap decorations at the Dollar Store, dug through stuff I already had, and my mom brought along some things to use, as well.
I had just seen a fun spider cake on one of the blogs I read, so I went with that. It's a four-layer Oreo cake with homemade whipped cream and Oreo frosting. The spiders on top and around the sides are mini and regular Oreos, with black frosting legs and candy eyes. I was able to make the cake and frosting ahead of time, then assemble everything at the Rock Farm the day of her party. Soooooo much easier than a Barbie cake.
Here's our weekend at the Rock Farm:
Another Rock Farm birthday success.
