If not already frozen, place 6 Tablespoons of the butter in the freezer for at least 10 minutes.
Preheat oven to 350 degrees F. Line a large baking sheet with parchment paper or a silicone baking mat and set aside.
In a large mixing bowl, combine flour, sugar, baking powder, cinnamon, salt, and nutmeg. Whisk to combine. Stir in the cinnamon chips.
In a large liquid measuring cup, whisk together the cream, egg, and vanilla extract.
Remove butter from the freezer, and use a box grater to shred it into small pieces.
Add shredded butter and the liquid mixture to the dry ingredients. Stir to combine. The dough should be crumbly and still have streaks of butter. Knead it very briefly with well-floured hands, just until evenly combined. If the dough is too dry to come together, add a tiny bit more cream, just a couple drops at a time. Do your best to press and work the dough gently so that it comes together but you still have some visible pieces of butter.
Turn out the dough onto a lightly-floured work surface, and use your hands to gently shape it into a flat disk, roughly 9” across. Cut the disk into 8 wedges, just like a pizza. Transfer wedges to the prepared baking sheet.
Melt the remaining 1 Tablespoon butter and brush it lightly over the cut scones. Sprinkle each scone lightly with raw sugar.
Bake scones on a middle oven rack for 18-20 minutes, until the tops are lightly browned. Let cool about 10 minutes and serve, or transfer to a wire rack to cool completely.
