01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together the flour, sugar, baking powder, salt, and orange zest.
03 - Add the cold cubed butter and use a pastry cutter or fingertips to blend it into the flour until the mixture resembles coarse crumbs.
04 - In a separate bowl, whisk together the heavy cream, egg, and vanilla extract. Pour this mixture over the dry ingredients.
05 - Gently fold in the cranberries using a fork until the dough just begins to come together, taking care not to overmix.
06 - Transfer the dough onto a lightly floured surface and pat it into a circle approximately 7 to 8 inches in diameter and 1 inch thick.
07 - Slice the dough into 8 equal wedges and arrange them on the prepared baking sheet, spacing them apart.
08 - Lightly brush the tops of the wedges with extra heavy cream.
09 - Bake for 16 to 18 minutes until golden brown and cooked through. Allow to cool slightly on a wire rack.
10 - Whisk together the powdered sugar, fresh orange juice, and orange zest until smooth. Drizzle the glaze over the slightly cooled scones.
