I recently came up with a new option for edible favors. For a while now I have been making decorated butter cookies like the tiered cake cookies shown in the two pictures below. I recently decided to try taking it to another level by creating a box made entirely out of sugar and using a decorated cookie as the lid.
To make the edible sugar boxes I add a little bit of water to sugar to make it the consistency of sand. Then I used various containers to mold the sugar like you would make a sand castle at the beach. I let the sugar hard for a few hours then turned the box over and hollowed out the inside. This is the difficult part since you have to be very gentle as to not break the sugar. Once it is left to harden over night it becomes very sturdy. This is a great way to make a completely edible favor. The box can be filled with M&Ms, almonds, or any other candy.
