Dehydrate at 165 degrees F for 10 minutes. Turn down to 115 degrees and dehydrate until melted. Should take about 30 minutes or so.
Stir it all together and put in the freezer for about 30 minutes or until solid, or put directly in the fridge for a couple of hours.
Notes
You could use an oven at it's lowest temperature, with the door open. Times vary, keep a close eye. Store in the fridge. Fudge starts to melt around 78 degrees.
