Heat oven to 350 degrees. Spray 2 9x5 loaf pans with non stick spray.
In a bowl mix together coconut oil and sugar. Use a fork or a pastry cutter. Stir in eggs until well combined. Add bananas, buttermilk, and vanilla; mix well.
Add flour, baking powder, salt, and baking soda. Mix until just barely combined.
Fold in chocolate chips and coconut.
Divide batter between the 2 loaf pans. Bake for 40-50 minute, until a tester comes out clean.
Let cool for 10 minutes, before removing from the pan to cool completely.
