Preheat oven to 350 F. Line the bottom of two 8" baking pans with parchment paper and set aside.
In a large bowl, whisk together the almond flour, cinnamon, baking soda, baking powder, and salt.
In a separate medium bowl, mix together the coconut oil, bananas, eggs, maple syrup, and vanilla.
Add the wet ingredients into the dry ingredients, stirring it together until it forms a batter. The batter will be thick.
Divide the batter evenly between both pans, smoothing the tops so it's flat.
Bake for about 35-40 minutes, until the cake is lightly browned and the center is firm to the touch.
Remove the cakes from the oven and cool completely on a rack.
Slice the cakes in half to create four cake layers.
