Firstly, I know you will probably think "I can't be bothered", but I would truly be grateful if someone could help me create a really simple chocolate bar or something similar with just these ingredients, I don't really care if it isn't insanely tasty because I am not fussy, just want something to be able to carry around with me.

Stevia powder (or liquid, if powder won't work as effectively.)
Coconut Flour
Cocoa Butter
Cocoa Nibs (don't tolerate these too well so would only want to use a small handful)
Grass-fed butter (still eat lots of this even though it isn't true paleo)
Organic Eggs

Is it possible to create something with this? I would only want to make a small batch at a time as it is just me eating it.

Thanks SO much to anyone who can come up with something.
