Preheat oven to 375°F. Line a baking sheet with parchment paper or a silicone baking mat and set aside. In a large bowl, whisk together all purpose flour, granulated sugar, brown sugar, baking powder and salt.
2 cups all purpose flour, ½ cup granulated sugar, ¼ cup light brown sugar, 2 teaspoons baking powder, ½ teaspoon salt
Using a pastry cutter, cut the butter into the flour mixture until only a handful of small, pea-sized pieces of butter remain. 6 tablespoons unsalted butter
In a separate bowl, whisk together the heavy cream, egg and vanilla extract.
¾ cup heavy cream, 1 large egg, 2 teaspoons vanilla extract
Pour cream mixture into flour mixture and stir with a fork until mostly combined.
Add in the cranberries and gently fold everything together until a dough forms.
1 cup cranberries
Divide the dough in two. Turn dough out onto a lightly floured surface and pat into two discs about 1 inch thick.
Use a large knife or bench scraper to cut into 6 to 8 wedges. Transfer scones to the prepared baking sheet. Optional: Brush the tops of scones with heavy cream. Sprinkle with sanding sugar if desired. 1 tablespoon heavy cream, 2 tablespoons sanding sugar
Bake for 16 to 19 minutes or until golden brown and cooked through, rotating baking sheet halfway through.
Serve warm or room temperature. Store leftovers in an airtight container. Best enjoyed the day they are baked.
