Per heat the oven to 400 degrees and prepare a baking sheet with parchment paper.
In a large bowl whisk together flour, sugar, baking powder, and salt.
Using a box grater, grate the frozen butter and dump into the flour. Toss with your hands to ensure the butter is fully coated in flour. Really try to keep the butter cold as much as possible. If you get delayed, pop the whole bowl in the fridge to keep it cool.
Next up, pour in the buttermilk, egg, and vanilla. Mix together to combine. Do not over mix. Once you have a shaggy dough, pour onto the counter and using your hands bring the dough together into a ball. Now form an 8 inch circle and and cut into 8 equal size wedges. Place onto the prepared baking sheet.
Before sliding the try into the oven, I highly suggest brushing the tops of the scones with a little bit of cream or buttermilk. This will help make golden brown tops.
Bake for 25 minutes or until golden brown.
Remove from oven, allow to cool for 10 minutes and then dig in!
