I came up with this idea not long ago, and have been waiting for the right cake to try it on! I was so excited when i was given this order and told to 'do whatever I wanted' :) I was a a little apprehensive about the miniature cupcakes working inside of the parcel box.. but in the end it all turned out to plan! 10" square vanilla sponge with jam and buttercream, plus 24 miniature vanilla cupcakes.
The cake was liked that much, the order i had the week after changed their original design to another parcel box! This one an 8" square with jam and buttercream.
