Building Blocks Cakes- I took a few short cuts after reading the comments on this. It was soooo easy and my 5 year old was really happy. Skip the crumb coat, skip slicing it into several blocks. I made one giant Lego cake out of my 13x9 cake. Then used his mini figures to hold the candles. I stored it in the microwave overnight since I had nothing to cover it with that wouldn't ruin the frosting.
