Creating Matcha Blueberry Muffins is a breezy process if you follow these organized steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C). Line a muffin tin with paper liners or grease it lightly.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking powder, baking soda, salt, and matcha powder until thoroughly combined.
3. Whisk Wet Ingredients: In another bowl, whisk together the buttermilk, egg, melted butter, and vanilla extract until well mixed.
4. Combine Ingredients: Gradually fold the wet ingredients into the dry ingredients. Mix gently until just combined; avoid overmixing.
5. Incorporate Blueberries: Gently fold in the blueberries, ensuring they are evenly distributed within the batter.
6. Fill Muffin Tin: Spoon the batter into each muffin cup, filling them about ¾ full.
7. Bake: Place the muffin tin in the preheated oven and bake for 20-25 minutes or until a toothpick inserted into the center comes out clean.
8. Cool Down: Once baked, allow the muffins to cool in the tin for 5-10 minutes before transferring them to a wire rack to cool completely.
9. Serve or Store: Enjoy your muffins warm or store them in an airtight container for up to three days.

With these clear steps, you can easily create a delicious batch of Matcha Blueberry Muffins that will impress anyone lucky enough to try them!
