01 - Preheat 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 until evenly mixed.
03 - Add cold, cubed butter to the dry ingredients and cut it in using a pastry cutter or your fingertips until the mixture resembles coarse crumbs.
04 - In a separate bowl, whisk heavy cream, egg, and vanilla extract until smooth.
05 - Pour the wet mixture into the dry mixture, add cranberries, and gently stir just until a shaggy dough forms without overmixing.
06 - Turn the dough onto a lightly floured surface and pat it into a 1-inch thick circle approximately 7 to 8 inches wide.
07 - Slice the dough circle into 8 wedges and place them on the prepared baking sheet, spaced slightly apart.
08 - Brush the tops of the wedges with a little heavy cream to promote browning during baking.
09 - Bake in the preheated oven for 16 to 18 minutes until the scones are golden and fully cooked.
10 - Allow the scones to cool on the baking sheet for 10 minutes before transferring to a wire rack.
11 - Whisk together powdered sugar, fresh orange juice, and orange zest until smooth, then drizzle the glaze over the warm scones before serving.
