In a large bowl, whisk together the mashed bananas, peanut butter, maple syrup, eggs, and vanilla until smooth
In another bowl, mix the almond flour, baking soda, cinnamon, and sea salt.
Pour the dry ingredients into the wet mixture, stirring until you have a uniform batter. It's important not to overmix.
