Preheat your oven to 350F.
Whisk together the flour, baking powder, salt and matcha in a bowl.
In a separate bowl, whisk together the butter, maple syrup, and egg until well combined.
Pour the dry ingredients in with the wet and mix until smooth. You want to mix by hand for about a minute, just to form a little gluten and hold in the batter.
Pour the batter into six muffin lined muffin cups. Bake at 350F for 20-25 minutes or until you can insert a toothpick and it comes out clean.
Once out of the oven, sprinkle powdered sugar on top and serve!
