Oil your bread pan with coconut oil
In a large bowl, add the peeled bananas and using the back of a fork, mash them well. No large chunks should remain. Try to mash as much as possible.
To the bananas, add in the brown sugar, melted coconut oil, unsweetened applesauce, and vanilla. Stir together with a silicone spatula.
Next, sift in the flour, baking powder, baking soda, cinnamon and nutmeg. Add in the salt.
Stir again just until combined.
Gently fold in walnut pieces if you are adding.
Pour into greased bread pan and tap the bottom of the pan to ensure it's evenly leveled.
In a small bowl, combine the sparkling sugar and cinnamon and sprinkle evenly across the top.
Place in oven for 35-45 minutes. When done, a toothpick inserted when come out clean.
*The top of the bread should be a deep brown color. If after 45 minutes, your bread needs more time, cover the top with foil and continue cooking in 5 minute intervals until the toothpick comes out clean.
Remove from oven and let cool for 15 minutes in pan. Then carefully remove and place on a cooling rack until completely cooled.
