Preheat your oven to 180°C (350°F). Grease and line an 8 x 4-inch loaf pan and set it aside.
In a large mixing bowl, combine the almond flour, sugar, baking powder, salt, and cinnamon, mixing well.
In another bowl, whisk together the mashed bananas, eggs, coconut oil, and vanilla extract.
Pour the wet ingredients into the dry ingredients and mix until just combined. If you're adding chocolate chips, fold them in at this stage.
Transfer the batter into the prepared loaf pan and bake for 45-50 minutes, or until a skewer inserted into the center comes out mostly clean.
Once baked, remove the loaf from the oven and allow it to cool completely before slicing.
