You can open the chest after completing the Sweet Dreams Quest.

I got a Rainbow Waffles Recipe in it. 

According to Eudocia:

The recipes for the rainbow waffles, nightsky cupcake, matcha turtle and rose milk cake are flavour quest rewards and an invitation to bake those sweets. Perhaps someone wants to give it a shot.
