This was my first Tiffany box cake, and hopefully not my last! The mom had me put the ring box for her daughter down inside the cake, which I carefully hollowed out a shaft and then iced it and put a thin layer of MMF inside to give it a protective cubby. It was so fun to do and was a hit! I can give instructions to anyone who would possibly need to know how to put a ring box inside a cake~it was simple and turned out wonderfully!
