Preheat oven to 350° Fahrenheit and line a 9x5-inch loaf pan with parchment paper.

Whisk together the almond flour, coconut sugar, baking soda, baking powder, and cinnamon in a large bowl.

Add in the melted coconut oil, mashed banana, eggs, and vanilla extract – mix until fully combined. Fold in chocolate chips if using, until evenly dispersed throughout batter.

Transfer batter to prepared loaf pan and bake for 40-50 minutes or until a toothpick inserted down the center of the bread comes out clean. Remove from the oven and transfer to a wire cooling rack, cool bread completely (about 1 hour) before slicing.
