I used to make my own chocolate treats all the time:


100% pure dark bakers chocolate
coconut oil
sweeten to taste - I used stevia and sugar free Torani syrup, French Vanilla

about maybe 3 parts chocolate to 1 part coconut oil - I just eyeballed it and it varied all the time, melt together in a double boiler or in microwave, pour in a chocolate mold, silicone ice tray or flat onto wax paper or parchment, freeze.
The flat piece can be broken up. I always stored in the freezer or fridge.

These are delicious - just as good as any bar out there, without a bunch of additives and you control the sweetness. I weaned myself off of artificial sweeteners, for the most part, but I still make them occasionally for my diabetic husband.
