Preheat the dehydrator to 125°F. Set a drying sheet on a dehydrator tray.
Place the ingredients in a blender and blend until smooth.
Pour the cracker mixture onto the drying sheet.
Pick up the dehydrator tray and slap on the counter a couple times to level it.
Spread the mixture into a 10-inch square on the drying sheet, smoothing the surface with a rubber spatula and using a straight edge to get nice edges.
Dehydrate for 6 hours.
Remove the tray from the dehydrator and use a pizza wheel or straight edge to cut the square into 2-inch square crackers.
Place the tray back in the dehydrator for another 6 hours.
When the crackers have completely cooled, snap them apart along the perforated lines.
