01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together flour, sugar, baking powder, and salt until evenly distributed.
03 - Add the cold cubed butter to the dry ingredients and incorporate using a pastry cutter or fingertips until the mixture resembles coarse crumbs.
04 - In a separate bowl, whisk together heavy cream, egg, and vanilla extract until combined.
05 - Pour wet ingredients into the dry mixture and gently stir until just combined, avoiding overmixing.
06 - Fold in the semisweet chocolate chips carefully to maintain dough texture.
07 - Turn the dough onto a lightly floured surface and pat into an 8-inch round about 1 inch thick.
08 - Cut the dough into 8 equal wedges and place them on the prepared baking sheet, spacing slightly apart.
09 - Brush the tops lightly with additional heavy cream to promote browning.
10 - Bake for 16 to 18 minutes, or until the scones are golden brown. Allow to cool slightly before serving.
