01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together flour, matcha, sugar, baking powder, and salt until well blended.
03 - Add cold, cubed butter to the dry mixture. Cut in using a pastry cutter or fingertips until the mixture resembles coarse crumbs with pea-sized butter pieces remaining.
04 - In a separate bowl, whisk together cold milk, egg, and vanilla extract until combined.
05 - Pour the wet ingredients into the dry mixture. Add dried cranberries. Stir gently with a spatula just until the dough comes together—do not overmix.
06 - Turn dough onto a lightly floured surface. Gently pat into a 1-inch thick circle. Cut into 8 wedges and arrange on the prepared baking sheet, spacing 2 inches apart.
07 - Brush tops with milk and sprinkle with coarse sugar if desired. Bake for 16-18 minutes until scones are set and lightly golden at the edges.
08 - Transfer to a wire rack and cool for 10 minutes before serving warm.
