Please follow the directions exactly or else you may have issues with getting the ingredients to mix together well! You may also have issues if you add or change any of the ingredients or amounts.
Combine all the ingredients, except for the honey, in a small pot and mix together until decently well combined. Turn on the heat to the lowest possible setting and stir continuously until no more lumps remain. Don't heat for too long or the oil will start to separate. This really shouldn't happen if you follow directions and don't make any changes to the recipe, but if it does, refrigerate the pot for a few minutes, stir, refrigerate, stir, etc. until the oil has been incorporated. Then gently reheat until it's soft enough to stir in the honey.
Once no more lumps remain, remove from the heat and stir in the honey or other sweetener.
Taste and add more salt. Make sure to add enough. It brings out the chocolate taste and the fudge will taste flat without enough.
Pour into mini muffin liners or a container lined with parchment paper. Refrigerate for 1 hour and then cut into pieces.
Refrigerate for up to 1 week (they'll likely last for several weeks but I'm playing it safe!). They're fine at room temperature (though you should keep the butter and maple versions refrigerated) but are chewier and are slightly chewy when chilled. They're also great frozen (and perhaps thawed a little bit).
