Measure your butter/coconut oil, cocoa, honey/maple syrup, salt, vanilla and optional nut butter together in the bowl of a stand mixer or use an electric hand mixer to mix it all up. You can do it by hand, but cocoa powder can be stubborn.
If you want to mix things into the fudge, add em in.
Line a pie plate or loaf pan with parchment, wax paper or foil.
Scoop your fudge in and smooth it down.
My favourite time to add things into the fudge is at this point, press them into the top of the fudge.
Chill in freezer at least an hour, until firm, or if youre patient, in the fridge for more hours.
When ready to eat, cut it up up into 1 inch squares, and move to a container with a lid or cover the pan with foil/plastic wrap.
Store in the fridge or freezer and enjoy!
