Preheat your oven to 180℃, line a 9-inch loaf pan with lightly greased parchment (leave some overhanging parchment ; it helps to lift the still-warm bread out).
Whisk all the dry ingredients together in a large bowl.
In another bowl, whisk together the eggs, coconut oil, coffee and mashed bananas.
Fold in the dry ingredients until just combined (do not overmix or the soda bicarb will go flat and the bread will not rise) and pour into the prepared pan.
Bake for 30-45 minutes or till a skewer inserted into the centre of the loaf comes out clean.
Remove and cool completely on a wire rack before slicing.
