01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together flour, sugar, baking powder, salt, and orange zest until evenly mixed.
03 - Add the cold, cubed butter to the dry ingredients. Cut it in using a pastry cutter or fingertips until mixture resembles coarse crumbs.
04 - In a separate bowl, whisk heavy cream, egg, and vanilla extract until fully combined.
05 - Pour the wet mixture into the dry ingredients and add cranberries. Gently mix until a shaggy dough forms, taking care not to overwork it.
06 - Turn dough onto a lightly floured surface. Pat gently into a 1-inch thick circle approximately 7 to 8 inches in diameter.
07 - Cut the dough circle into 8 equal wedges. Place them spaced slightly apart on the prepared baking sheet.
08 - Brush the tops of each scone lightly with heavy cream to promote browning.
09 - Bake for 16 to 18 minutes, or until golden brown and cooked through.
10 - Allow scones to cool on the baking sheet for 10 minutes before transferring to a wire rack.
11 - Whisk powdered sugar, fresh orange juice, and orange zest until smooth. Drizzle over scones while slightly warm.
