Preheat the oven to 400℉. Line a baking sheet with parchment paper and set aside.
In a large mixing bowl, whisk together the dry ingredients; all-purpose flour, granulated sugar, baking powder, orange zest, and salt until combined.
2 cups all-purpose flour, 1/2 cup granulated sugar, 2½ teaspoons baking powder, 2 tablespoons fresh orange zest, ½ teaspoon kosher salt
Use a box grater to grate the frozen butter. Add the grated butter to the bowl of dry ingredients. Use a pastry cutter to cut the butter into the flour until there are pea-sized crumbs. * Do not grab the butter from the freezer until right before grating it. It needs to be grated completely frozen straight from the freezer. 1/2 cup (1 stick) FROZEN butter
In a medium bowl, whisk together the heavy cream, whisked large egg, and vanilla extract until smooth.
1/2 cup heavy cream, 1 large egg, 2 teaspoons vanilla extract
Slowly pour the bowl of wet ingredients into the bowl of dry ingredients (butter and flour mixture). Add the halved frozen cranberries and gently stir everything together just until it comes together as a dough.* Don't overmix because when you go in with your hands, in the next step, the dough will come together more. 1 cup FROZEN halved cranberries
Cover your hands with flour, then work the dough gently for a few times with your hands to bring it together in a ball.
Transfer the dough ball to a lightly floured surface on a clean countertop or large cutting board. Form it into an 8-inch flat & thick disc shape. Divide the disc into 8 equal wedges and then transfer the wedges to the prepared baking sheet with parchment paper.
Bake for 20-25 minutes or until golden browned. Remove the pan from the oven and allow to cook for 10 minutes (on the warm baking sheet) before removing the scones to a cooling rack.
Make the glaze by combining the powdered sugar and fresh orange juice until blended. Add the orange glaze to a piping bag, a sandwich bag with the tip cut off, or just use a fork to drizzle it over the tops of each scone.
1 cup powdered sugar, 2 tablespoons fresh orange juice
Serve the scones warm (my preferred way) or at room temperature.
