First, preheat the oven to 350º and line a muffin tin with muffin liners. Set aside.
Next combine wet ingredients. In a large mixing bowl, mash a medium banana until there are minimal to no lumps, then add the rest of the wet ingredients to the bowl (except for the coconut oil). Mix well. Set aside.
In a separate mixing bowl, combine dry ingredients.
Add dry ingredients to the wet mix until smooth. Once combined, add the melted coconut oil and mix again.
Transfer batter into muffin tin, filling each muffin about 3/4 of the way full (these are going to be big muffins!). You should get around 12-14 muffins.
Bake muffins at 350ºF for 16-18 minutes.
Remove from oven and let cool for 5-10 minutes in the muffin tin before transferring muffins to a cooling rack.
While muffins are cooling, combine ingredients for the glaze. Once muffins have fully cooled (this is important), either dip the muffin tops into the glaze or drizzle your muffin tips with glaze.
Either eat immediately (because who can wait) or set aside to allow the glaze to dry.
