Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
Whisk together the flour, sugar, baking powder, and salt in a large bowl.
Cut the cold butter into the flour mixture until coarse crumbs form.
Fold in the chocolate chips.
In a separate bowl, whisk together the egg, heavy cream, and vanilla extract.
Pour the wet mixture into the dry ingredients and gently stir until a shaggy dough forms.
Transfer the dough to a lightly floured surface and gently shape it into a round disk about 1 inch thick.
Cut the dough into 8 wedges.
Arrange the wedges on the prepared baking sheet. If desired, brush the tops lightly with cream.
Bake for 15–20 minutes, or until lightly golden.
Cool for several minutes before serving.
Enjoy warm or at room temperature.
