01 - Set the oven to 400°F and line a baking sheet with parchment paper.
02 - Whisk together flour, sugar, baking powder, and salt in a large bowl.
03 - Add cold, cubed butter and cut it into the dry ingredients using a pastry blender or your fingers until the mixture resembles coarse crumbs.
04 - In a separate bowl, whisk together heavy cream, egg, orange zest, and vanilla extract.
05 - Pour the wet mixture over the dry ingredients, add cranberries, and stir gently just until combined to avoid overmixing.
06 - Turn the dough onto a lightly floured surface and pat it into an 8-inch diameter circle about 1 inch thick.

08 - Brush the tops with additional cream and sprinkle with coarse sugar if desired.
09 - Bake for 16 to 18 minutes until scones are golden brown. Remove and cool on a wire rack.
