Preparation

1. Preheat oven to 400º F and line a baking sheet with parchment paper.
2. In a medium bowl, whisk together flour, sugar, baking powder, 1/2 teaspoon cinnamon and salt.
3. Add the grated butter (or you can pulse it in food processor) to the flour mixture and use a pastry cutter or two forks to incorporate it.
4. In a small bowl, whisk together 1 egg, heavy cream or buttermilk, and vanilla extract. Once combined, pour into the flour mixture.
5. Mix until a rough dough comes together, then gently knead into an 8-inch circle and transfer to baking sheet. Cut dough (like a pie) into 12 pieces.
6. Brush dough with remaining egg, then sprinkle with 1 tablespoon sugar and remaining cinnamon.
7. Bake for 20-25 minutes or until lightly golden and cooked through.
8. Remove from oven and let cool 10 minutes before serving.
9. For the glaze: whisk ingredients together in a small bowl, then drizzle over cooled scones and let set.
