01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Whisk together flour, granulated sugar, baking powder, and salt in a large bowl.
03 - Incorporate cold, cubed butter into the flour mixture using a pastry cutter or fingertips until the mixture resembles coarse crumbs.
04 - In a separate bowl, whisk cream, egg, and vanilla extract. Pour into the dry mixture and gently mix until just combined.
05 - Turn the dough onto a lightly floured surface. Roll or pat into a rectangle approximately 1/2-inch thick.
06 - Mix brown sugar and cinnamon in a small bowl. Brush melted butter over the dough, sprinkle the cinnamon sugar evenly, and top with chocolate chips.
07 - Roll up dough from the long edge as for a cinnamon roll, flatten gently into a log, then cut into 8 equal wedges. Arrange them on the prepared baking sheet.
08 - Brush tops with a small amount of cream. Bake for 16 to 18 minutes, or until golden brown and set. Allow to cool slightly.
09 - Whisk powdered sugar, vanilla, and milk until smooth. Drizzle glaze over the warm scones if desired.
