If your coconut butter is too hard, place jar, without cover, in the mircowave for 30 seconds, stir well and it should be soft enough to scoop to measure.
Place a piece of parchment, let it hang over edges for easy removal, into an 8 x 8 pan.
Place all ingredients into a stand mixer and blend until smooth. Taste and adjust sweetener. Spread this into the pan.
Top with optional pecans if desired.
Refrigerate until hardened, about 1 hour. Remove from pan onto a cutting board. Slice into 24 pieces.
Keep refrigerated. When ready to serve allow fudge to sit out on counter to soften, about 15 minutes.
