Preheat oven to 350 degrees F and spray silicone muffin tin with cooking spray. Set aside. In a powerful blender or food processor, add bananas, eggs, vanilla, cinnamon, baking soda + powder, salt and process until smooth. Add almond flour and process just enough to combine. Pause, scrape the walls and process just a bit again to combine. Add chocolate chips and stir with a spatula. Using an ice cream scoop, divide batter between 12 openings of previously prepared muffin tin and bake for 30 minutes, or until golden brown and toothpick inserted come out clean. Remove from the oven, let cool 20 minutes and enjoy.
