Preheat oven to 350°F degrees. Place your flexipan mold or tray of choice on your perforated baking sheet.
Mix together (using your whisk or mixer) banana, egg, vanilla, maple syrup & cinnamon. In another bowl, combine flour, baking powder, baking soda and salt. Add dry ingredients to wet ingredients and mix until combined. Using your blender spatula, fold in melted butter.
Pour batter into mold or tray of choice.
Bake for 30-40 minutes depending on the size of your mold. Check for doneness after 30 minutes but understand that a full loaf like the one pictured will take 35-40 minutes to cook and individual muffins like a mini muffin will cook in about 20 minutes. I would check muffins after 18 minutes.
