In a large mixing bowl, mash the banana and add in all the wet ingredients. Whisk thoroughly to combine.
In a seperate bowl, add in all the dry ingredients and whisk also to combine.
Add the wet ingredients into the dry and whisk to combine, switching to a spatula if necessary. Add in the oats, coconut and seeds and fold it into the batter. Mix till everything is well combined, don't overmix.
Transfer to a parchment paper lined loaf pan (grease the sides as well). And with wet hands, smooth the top of the bread making sure not to introduce excess water.
Brush the top with melted butter and sprinkle the toppings on the bread if desired.
Bake in a preheated oven at 350 degrees fahrenheit on the center rack for 40 - 50 minutes. (Reduce the heat half way through baking if necessary.)
After baking, let it cool for 5 minutes in the pan, then take it out. Let cool down to room temperature before slicing as it will crumble if hot.
This bread can be sliced and frozen for a healthy snack or as part of meal prep. Serve and enjoy!
