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 flour mixture. Use a pastry cutter or fingertips to work butter into dry ingredients until 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 wet ingredients into dry mixture. Add dried cranberries. Stir gently with a spatula just until dough comes together—do not overmix. Dough will be slightly shaggy.
06 - Turn dough onto lightly floured surface. Gently pat into a 1-inch thick circle. Cut into 8 equal wedges.
07 - Place scones on prepared baking sheet, spacing 2 inches apart. Brush tops with milk and sprinkle with coarse sugar if desired.
08 - Bake for 16–18 minutes until scones are set and edges are lightly golden.
09 - Transfer scones to wire rack. Cool for 10 minutes before serving warm.
