Follow these simple steps to create your Matcha Cupcakes:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line a cupcake tin with paper liners.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, granulated sugar, matcha powder, baking powder, baking soda, and salt.
3. Cream Butter: In a large bowl, beat the softened butter with an electric mixer until creamy.
4. Add Eggs: Add the eggs one at a time, mixing well after each addition.
5. Combine Wet Ingredients: Stir in the milk and vanilla extract until well combined.
6. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, mixing until just combined. Do not overmix.
7. Fill Cupcake Liners: Spoon the batter into the prepared cupcake liners, filling them about 2/3 full.
8. Bake: Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
9. Cool: Remove from the oven and allow the cupcakes to cool in the pan for 10 minutes. Transfer them to a wire rack to cool completely.

For the Frosting (Optional)

10. Make Frosting: In a large bowl, beat the softened butter until creamy. Gradually add powdered sugar, matcha powder, milk, and vanilla extract. Mix until smooth and fluffy.
11. Frost the Cupcakes: Once the cupcakes are completely cool, use a piping bag or a knife to frost each cupcake with the matcha frosting.
