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 to the dry mixture. Using a pastry cutter or fingertips, work butter into the flour until the mixture resembles coarse crumbs.
04 - In a separate bowl, whisk the heavy cream, egg, and vanilla extract together until blended.
05 - Pour the wet ingredients into the dry ingredients. Add cranberries and gently mix just until a shaggy dough forms, avoiding overmixing.
06 - Turn the dough onto a lightly floured surface. Gently pat into a 1-inch thick circle about 7 to 8 inches in diameter.
07 - Cut the dough into 8 wedges and place them on the prepared baking sheet spaced slightly apart.
08 - Brush the tops of the wedges with additional heavy cream to promote browning.
09 - Bake for 16 to 18 minutes or until golden and cooked through.
10 - Allow scones to cool on the baking sheet for 10 minutes, then transfer to a wire rack.
11 - Whisk together powdered sugar, fresh orange juice, and orange zest until smooth. Drizzle over warm scones before serving.
