01 - Preheat the oven to 400°F and line a baking sheet with parchment paper.
02 - In a large bowl, whisk together the flour, sugar, baking powder, and salt until evenly mixed.
03 - Add the cold cubed butter to the dry mixture and cut in using a pastry blender or fingers until the mixture resembles coarse crumbs.
04 - In a separate bowl, whisk together the heavy cream, egg, orange zest, and vanilla extract until combined.
05 - Pour the wet ingredients over the dry ingredients and gently stir with a spatula until just combined.
06 - Carefully fold in the halved cranberries without overmixing the dough to maintain tenderness.
07 - Transfer the dough onto a lightly floured surface and pat into an 8-inch diameter circle approximately 1 inch thick.
08 - Cut the dough circle into 8 equal wedges and place them evenly spaced on the prepared baking sheet.
09 - Brush the tops of the wedges with a little heavy cream and, if desired, sprinkle with coarse sugar.
10 - Bake in the preheated oven for 18 to 22 minutes, until the scones are golden brown and cooked through. Cool on a wire rack.
11 - Whisk the powdered sugar with 2 tablespoons of fresh orange juice, adding more juice to adjust consistency. Drizzle the glaze over cooled scones before serving.
