Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt.
Add the chilled, cubed butter to the dry ingredients. Using a pastry cutter or your fingers, mix until the mixture resembles coarse crumbs.
Fold in the dried cranberries and orange zest until evenly distributed.
In a separate bowl, whisk together the heavy cream, egg, and vanilla extract.
Pour the wet mixture into the flour mixture and stir until just combined. Avoid over-mixing; the dough should be slightly shaggy.
Turn the dough onto a lightly floured surface and knead gently for about 30 seconds. Pat the dough into a circle about 1 inch thick. Cut into 8 wedges and place them on the prepared baking sheet.
Bake in the preheated oven for 15-18 minutes or until the scones are lightly golden on top.
While the scones are baking, whisk together the powdered sugar and orange juice in a small bowl until smooth.
Once the scones are done, remove them from the oven and let them cool for a few minutes before drizzling the glaze on top.
Notes
Serve warm on a tiered serving stand, dusted with powdered sugar and garnished with fresh cranberries and orange slices.
