01 - Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
02 - In a large mixing bowl, whisk together flour, granulated sugar, baking powder, and salt.
03 - Add the cold, cubed unsalted butter to the dry ingredients. Use a pastry blender or your fingertips to cut the butter into the flour mixture until it resembles coarse crumbs.
04 - In a separate bowl, whisk together heavy cream, egg, vanilla extract, and orange zest. Pour this wet mixture over the dry ingredients and gently mix until just combined. Be careful not to overmix.
05 - Carefully fold in the halved cranberries into the dough, ensuring not to overwork the mixture.
06 - Turn the dough out onto a lightly floured surface. Pat the dough into a circle approximately 1 inch (2.5 cm) thick. Cut the circle into 8 equal wedges.
07 - Transfer the cut scone wedges to the prepared baking sheet. Brush the tops of the scones with a small amount of additional heavy cream to achieve a golden finish.
08 - Bake for 16–18 minutes, or until the scones are golden brown and have set. Remove from the oven and let them cool on a wire rack.
09 - For the glaze, whisk together the sifted powdered sugar, pure maple syrup, and enough milk or cream to achieve a thick yet pourable consistency. Drizzle the glaze evenly over the completely cooled scones.
