You’re right! You can buy a bigger size cake to accommodate your guests. The Money Cake can be an extra special cake. Tell the guest of honor that you need to cut the special cake first but they need to take off the decorations. When they pull on the one you attached the template, out will be their SURPRISE! Then you can serve the bigger size cake. Or you can buy, make or have a sheet cake made and place the kit on the sheet cake (you will need dowels to hold it in place). Then have another cake on top of The Money Cake kit.
