Preheat the oven to 300 degrees F. Position a cooling rack on top of a baking sheet.
Slice the banana bread width-wise. Then, slice into thin pieces that are each about 1/2 inch thick. Lightly brush one side of each slice with honey and place on the cooling rack.
Bake until golden and crispy, about 30 minutes. Allow to cool on the rack for 10 minutes. The biscotti will become more crisp as they cool.
