Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together 1 cup of all-purpose flour, 2 tablespoons of matcha powder, and 1/2 teaspoon of baking soda.

Step 3: Prepare the Wet Ingredients

In a large bowl, cream 1/2 cup softened butter with 1/2 cup granulated sugar until light and fluffy. Add 1 large egg and 1 teaspoon of vanilla extract, mixing until well combined.

Step 4: Combine and Fold

Gradually add the dry ingredients to the wet mixture, stirring until just combined. If desired, fold in 1/2 cup of white chocolate chips or chopped nuts.

Step 5: Bake the Cookies

Drop tablespoon-sized portions of dough onto the baking sheet, spacing them 2 inches apart. Bake for 10-12 minutes until the edges are lightly golden, then cool on a wire rack before serving.
