Step 1

In a medium size mixing bowl, whisk the flour, sugar, salt and baking powder together. Use a cheese grater to grate the butter into the bowl. Toss the grated butter with the flour mixture with a fork to coat and separate the pieces of butter. Cut the flour into the butter using a pastry cutter or a bench scraper until the mixture comes together in pea size crumbs. Add the chocolate chips to the mixture and stir.

Step 2

In a separate bowl, whisk the starter, egg, vanilla extract and heavy cream until smooth. Pour into the dry ingredients and use a fork to gently mix. The dough will be crumbly, resist the urge to add more liquid.

Step 3

Dump the dough onto a clean work surface and use your hands to press and shape the dough into an 8" disc shape. (Use a small amount of flour if needed to help it from sticking to the surface.)

Step 4

Cut the dough into 8 wedges using a bench scraper or a large knife. Arrange the wedges onto a parchment lined baking sheet with space in between each wedge. Place the baking sheet in the fridge to chill for 30 minutes.

Step 5

When ready to bake, preheat the oven to 400°F (204°C). Brush the top of the scones with heavy cream and sprinkle with sanding sugar. Bake for 20-25 minutes or until the scones are golden brown. Remove and serve warm.
