Use very ripe bananas with brown spots for best flavor and moisture. Spoon and level your gluten-free flour to avoid dense texture. Let the loaf cool at least 30 minutes before slicing to prevent crumbling. For dairy-free, use melted coconut oil or avocado oil. For refined sugar-free, substitute brown sugar with pure maple syrup and slightly reduce other liquids. Optional add-ins include chocolate chips, chopped walnuts, pecans, cinnamon, or blueberries.
