Add flour, baking powder, and salt to the food processor.
Cut the salted butter into squares before adding it to the food processor. This will help the butter mix evenly throughout the flour.
Pulse the butter into the flour mixture until the butter is pea-sized.
Next, add the sourdough starter, granulated sugar, and vanilla extract to the food processor and blend until the dough comes together. If the dough is looking a little dry, gradually add water.
Once the dough comes together, fold the chocolate chips into the dough.
Weigh the entire ball of scone dough and divide by eight. This is how much each scone should weigh.
Take the dough and roll it into a hockey puck shape. Make sure the dough is even in thickness.
Chill the dough for an hour.
Preheat your oven to 400 degrees after chilling and bake for 25 minutes.
While the classic chocolate chip sourdough scones bake, whisk powdered sugar and heavy cream to make icing. Add the icing to a ziploc bag and cut a hole in one of the corners of the bag. This will act as a piping bag for the icing.
Allow the scones to completely cool before adding icing and enjoy!
