Preheat oven to 400℉ and line a baking sheet with parchment paper or a perforated silicone mat.
In a large bowl combine flour, sugar, baking powder and salt and whisk to mix.
2 ½ cup All-purpose Flour, ½ cup Sugar, 1 tablespoon Baking Powder, ¼ teaspoon Salt
Add butter and cut in with a pastry cutter until the mixture resembles cornmeal texture.Pro Tip: Freeze the butter and grate it into your flour using a box grater! ½ cup Butter
In another bowl, whisk together the heavy cream, egg, and the scrapings of a fresh, plump vanilla bean, and the vanilla extract.
½ cup Heavy Cream, 1 large Egg, 1 large Vanilla Bean, 2 teaspoon Vanilla Extract
Add the liquid mixture to the flour mixture and stir until dough forms a ball. If using a stand mixer, use a low setting and mix until just barely combined, some flour will still be visible.
Put the dough onto a lightly floured surface, pull it together and knead lightly until dough comes together into a ball.
Divide into 4 balls of dough and roll each out into disks 1 inch thick, about 6 inches in diameter.
Divide each disk into 6 to 8 wedges and transfer them to the prepared baking sheet about 2 inches apart. Bake 10-12 minutes, or until edges begin to get golden brown.
Transfer scones to a cooling rack to cool completely.
To make the vanilla glaze, whisk together the cream one table spoon at a time until you have thick flowing liquid.
2 cups Powdered Sugar, 4 tablespoon Heavy Cream, 1 teaspoon Vanilla Extract
You can dip the cooled scone top in the glaze, or brush it on with a pastry brush. Place the glazed scones back onto cooling rack to harden.
