Combine the bananas and peanut butter in a container with a lid.
Place the lid on the container and give it a good shake until the banana slices are coated with the peanut butter. If the peanut butter is too thick and not mixing well, add 2 to 3 tablespoons of water.
Remove the individual slices of banana from the container and place them on the dehydrator trays. Leave space between so they are not touching.
Dehydrate at 160° for 8 hours.
Remove from the dehydrator and refrigerate in an airtight container.
