Begin by preheating your oven to 400°F (200°C). While the oven is warming up, prepare a baking sheet by lining it with parchment paper to prevent sticking.
In a large mixing bowl, combine the all-purpose flour, granulated sugar, baking powder, and salt. Whisk these dry ingredients together until they are well blended and no lumps remain.
Add the cold, cubed unsalted butter to the dry mixture. Using a pastry cutter, fork, or your fingertips, incorporate the butter into the flour until the mixture resembles coarse crumbs, with small pea-sized pieces of butter remaining for flakiness.
Gently fold in the dried cranberries and orange zest, ensuring they are evenly distributed throughout the flour mixture for balanced flavor in every bite.
In a separate bowl, whisk together the buttermilk, large egg, and vanilla extract until fully combined; this will add moisture and richness to the dough.
Pour the wet ingredients into the bowl with the dry ingredients, and stir gently with a spoon or spatula. Mix until just combined—be cautious not to overmix, as this can lead to tough scones.
Lightly flour a clean surface and turn the dough out onto it. Gently pat the dough into a round disc about 1 inch thick, being careful not to overwork the dough.
Using a sharp knife or bench scraper, cut the dough into 8 equal wedges. Carefully transfer each wedge to the prepared baking sheet, ensuring there’s space between them for expansion during baking.
For a delightful crunchy topping, sprinkle each scone with the additional sugar before baking.
Bake in the preheated oven for 15-20 minutes, or until the scones are golden brown and a toothpick inserted into the center comes out clean, signaling they are fully baked.
Once finished, remove the scones from the oven and allow them to cool slightly on a wire rack. Serve them warm to enjoy their best flavor and texture.
Notes
Serve warm with clotted cream or butter for an indulgent treat.
