I would substitute the flour for coconut flour an powdered sugar for a suitable substitue an it might be clean enough to eat Cinnamon Crumb Banana Bread. Because anything with a crumb topping is automatically delicious and always a good idea!
Homemade Honey Oat Bread (You brush the top with warm honey and sprinkle the top with rolled oats before baking.) I made this today and used agave instead of honey and whole wheat instead of white floor. So yummy and so easy!
