Follow these simple steps to create your Matcha Butter Cookies:

1. Preheat Your Oven: Set your oven to 350°F (175°C) and prepare a baking sheet by lining it with parchment paper.
2. Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and sugar until light and fluffy. This process usually takes about 3-4 minutes.
3. Add the Egg and Vanilla: Incorporate the beaten egg and vanilla extract into the butter-sugar mixture until fully combined.
4. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, almond flour, matcha powder, baking powder, and salt.
5. Combine Wet and Dry Ingredients: Gradually mix the dry ingredients into the wet mixture, stirring until just combined. Be careful not to overmix.
6. Add Optional Ingredients: If desired, fold in the white chocolate chips or chopped nuts for added texture and flavor.
7. Scoop the Dough: Using a cookie scoop or tablespoon, drop balls of dough onto the prepared baking sheet, leaving space between each cookie.
8. Bake: Place the baking sheet in the preheated oven and bake for 10-12 minutes or until the edges are lightly golden.
9. Cool: After baking, allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
