In a large mixing bowl, combine the flour, matcha powder, baking powder, and salt. Set aside.
2 cups flour, 2 tablespoons matcha powder, 1 ½ teaspoons baking powder, ¼ teaspoon salt
In another large bowl, mash the bananas, then add the sugar, coconut oil, egg, and vanilla. Beat with a whisk or electric mixer until well combined.
2 bananas, ⅓ cup sugar, ¼ cup coconut oil, 1 egg, 1 teaspoon vanilla extract
Stir the milk into the banana mixture, then fold in the flour mixture until just combined.
1 cup whole milk
Distribute the batter evenly between 12 greased muffin cups, or use paper or silicone muffin cup liners. Sprinkle the coconut flakes over each muffin, if desired.
¼ cup sweetened coconut flakes
Bake for 20-22 minutes, until a toothpick inserted into the middle of the muffins comes out clean.
Remove from oven, let cool in the pan for 15 minutes, then remove and finish cooling on a wire rack.

Notes
Use virgin coconut oil for the best flavor.
If you don't have coconut oil, you can substitute butter, but just be aware that you won't get the coconut flavor in your muffins, they will just be banana matcha muffins (which are also delicious!).
If you don't have whole milk, you can substitute another milk but it may result in a less rich and flavorful muffin.
Skip the coconut flakes if you don't care for them.
