Preheat the oven to 180c and line a tray with baking paper.
In a mixing bowl, cream together the coconut oil, sugar, peanut butter and honey. Mash the banana and stir this into the wet ingredients.
Fold through the dry ingredients to form a smooth batter, then mix in the peanut butter chips (reserving a few extra for topping) to evenly distrubute.
Scoop out portions of the cookie dough and place onto your baking sheet. Press a couple of peanut butter chips into the centre of each cookie and bake these for around 11 minutes.
Allow to cool completly before serving.
