Add dry ingredients in a mixing bowl and mix until well combined.
Add 3 tbsp non-dairy milk and mashed bananas. Mix until a thick batter appears.
To make glaze, add rolled oats, coconut sugar, and water in a small bowl. Set aside.
Divide the batter into 8 muffin tins. Add glaze on top. Bake for 30 to 35 minutes and test doneness by inserting a toothpick in the center of one of the muffins, it should come out clean.
Remove from the oven and let it cool in the pan for 5 minutes. Once ready, enjoy!
