With 13 females, I agree, lack of Chocolate IS a disaster and sooth the savage beast. I tried storing chocolate (dark is better than milk chocolate) but it doesn't store very well. Then there is the problem of "inventory shrinkage" too.
Now I store cocoa powder, unsweetened and containing only pure cocoa solids (no cocoa butter). Cocoa powder with all of the natural fat of the beans removed stores well and it is not readily munched on.
Cocoa can be added hot reconstituted milk and some sugar, used in baking or add cocoa to coffee (or coffee substitute), with a touch of cinnamon, for a good beverage.
