1. Preheat the oven at 180°C
2. In a mixing bowl, combine the flour, baking soda and baking powder. Set aside.
3. In another bowl, add the mashed bananas and coconut oil and whisk until combined. Add in the brown sugar, honey, egg and vanilla extract and whisk it all together.
4. Add the dry ingredients to the wet ingredients and fold through, until well combined.
   
5. Add in the chocolate chips and fold them through the batter.
6. Pour into a rectangular cake pan lined with parchment paper. Tap on the counter so all the air pockets are eliminated. Place a sliced banana over the batter.
   
7. Bake for an hour or until a toothpick inserted comes out clean. Cool completely once baked, slice and serve.

Enjoy your meal!
