01 - Set the oven to 400°F and line a baking sheet with parchment paper.
02 - In a large bowl, whisk together flour, sugar, baking powder, salt, and orange zest.
03 - Add cold, cubed butter to the dry ingredients and cut it in using a pastry cutter or fingertips until the mixture resembles coarse crumbs.
04 - In a separate bowl, whisk heavy cream, egg, and vanilla extract until combined.
05 - Pour wet ingredients into the dry mixture, add cranberries, and gently mix just until a shaggy dough forms, avoiding overmixing.
06 - Turn the dough onto a lightly floured surface and gently pat into a 1-inch thick circle approximately 7 to 8 inches in diameter.
07 - Cut the dough circle into 8 wedges and place them on the prepared baking sheet, spacing slightly apart.
08 - Brush the tops of the wedges with a little heavy cream to promote a golden finish.
09 - Bake for 16 to 18 minutes or until the scones are golden brown and cooked through.
10 - Allow the 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, then drizzle over the slightly warm scones before serving.
