01 - Preheat your 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 the cold, cubed butter to the dry mixture. Use a pastry cutter or your fingertips to work it in until the mixture resembles coarse crumbs with some pea-sized pieces remaining.
04 - In a separate bowl, whisk together milk, egg, and vanilla extract until fully combined.
05 - Pour the wet ingredients into the dry mixture. Add dried cranberries. Gently fold with a spatula just until the dough comes together—do not overmix as this will toughen the scones.
06 - Turn the dough onto a lightly floured surface. Gently pat it into a disc about 1 inch thick. Handle minimally to keep the dough cold.
07 - Cut the dough into 8 equal wedges. Transfer them to the prepared baking sheet, leaving at least 2 inches of space between each scone for proper expansion.
08 - Brush the tops of each scone with the reserved tablespoon of milk. Sprinkle generously with coarse sugar for a crunchy, sweet topping.
09 - Bake for 16 to 18 minutes, or until the scones are set and lightly golden at the edges. The centers should feel firm when gently pressed.
10 - Transfer scones to a wire rack and let cool for 10 minutes. Serve warm with clotted cream, lemon curd, or butter.
