01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together all-purpose flour, granulated sugar, baking powder, and salt.
03 - Add cold, cubed butter to the dry mixture. Use a pastry cutter or fingertips to rub butter into the flour until coarse crumbs form.
04 - Stir dried cranberries into the crumbly mixture evenly.
05 - In a separate bowl, whisk heavy cream, egg, and vanilla extract until combined.
06 - Pour wet ingredients into the dry mixture and gently stir until just combined, avoiding overmixing.
07 - Turn dough onto a lightly floured surface. Pat into a 7-inch diameter circle about 1 inch thick.
08 - Cut dough into 8 wedges and transfer to the prepared baking sheet.
09 - Brush the tops lightly with extra heavy cream to encourage browning.
10 - Bake for 16 to 18 minutes, or until golden brown and cooked through.
11 - Allow scones to cool slightly. Serve warm accompanied by your preferred jam.
