Line your dehydrator with plastic liner that sits inside the tray, or cut our a piece of wax or parchment paper to line the machine tray. If you have an air fryer machine, it may also have a dehydrating feature - you can line the metal trays with wax or parchment paper, also.
Using a butter knife, spread out the honey onto the lined tray as evenly and thinly as possible. The layer of honey shouldn’t be more than around one-eighth of an inch thick.
Use the dehydrator setting on the machine that will dry the honey at about 120 degrees F (48 Celsius).
To test the honey to see if it has dried completely, break off a piece. If dried, the honey will audibly snap away from the remainder in the tray and be brittle - both looking and feeling like a thinned hunk of peanut brittle.
Once the honey is dried, turn off the machine, and start breaking it into chunks.
Place the chunks in your food processor or blender and pulverize them into a powder.
Immediately remove the powdered honey from the machine to avoid it absorbing excess moisture.
