Preheat your oven to 350 and line a loaf pan with parchment paper, with both sides sticking out for easy removal of the bread.
In a small mixing bowl, combine your dry ingredients and stir them together (flour, baking soda, salt and cinnamon).
In a large mixing bowl, mix together your coconut oil and brown sugar. Add in your mashed banana, eggs and vanilla and stir until all is well combined.
Pour your dry ingredients into your wet ingredients and mix them until all is well incorporated. Do not over-mix.
Pour your Banana Bread dough into your loaf pan and bake in the oven for 60-70 minutes, or till the top is set, the loaf does not jiggle at all, and a toothpick inserted comes out clean.
I recommend storing this bread in the fridge so it will keep longer. It will last about a week in the fridge.
