If you are using coconut oil, you will need to keep these in, and eat them straight from the fridge or freezer. If you used cocoa butter then they are fine stored at room temp, but i do find they start to form a powdery coat on them after a few days, i guess maybe from the lack of sugar and preservatives. So i keep them in the fridge. I usually double this mix and it makes an impressively big jar of chocolates!
