Sift: Sift the flour into a medium-sized mixing bowl. Then whisk in the sugar, baking powder, cinnamon, and salt. Set aside.
2 cups all-purpose flour, 1/3 cup granulated sugar, 1 tsp. ground cinnamon, 1 tsp. kosher salt, 1 Tbsp. baking powder
Cut in butter: Using a pastry blender, cut the butter into the flour. Alternatively, you can use your fingertips to flatten each butter piece between them. Continue smashing and rubbing until the butter looks like a coarse meal.
8 Tbsp. cold, unsalted butter
Cinnamon chips (Optional): Feel free to add 1/2 cup of cinnamon chips in this step.
Combine wet and dry: Pour the heavy cream and vanilla into the dry ingredients and stir until a soft, shaggy dough forms.
2/3 cup cold heavy cream, 1 tsp. vanilla
Form dough: Turn the dough out onto a lightly floured surface. Gently knead and fold just until combined so you can bring it into a circle, about 3/4 inch thickness. Pat the dough around the edges to make the circle neat.
Cut into wedges: Cut into 8 wedges with a chef’s knife or bench scraper. (Cut into 6 if you prefer a larger scone).
Chill: Make sure you have space in your freezer, then place a piece of parchment paper on a baking sheet and place scones on parchment. Freeze for 15-20 minutes Start Timer. Cold dough = best scones.
Preheat: While the scones chill, preheat the oven to 400°F.
Add topping: Brush the chilled scones with heavy cream. Combine cinnamon and sugar and sprinkle over the tops of each scone.
1 Tbsp. heavy cream, 1 Tbsp. sugar, 1/4 tsp. cinnamon
Bake: Bake the scones for 18-20 minutes Start Timer or until the tops are a light golden brown color. They should look puffed/risen and golden.
Make the glaze: Whisk together the ingredients for the glaze.
1/2 cup powdered sugar, 1-2 Tbsp. heavy cream, 1/2 tsp. vanilla
Top the scones: Drizzle over the scones or spread a layer on top of each scone. Sprinkle with any remaining cinnamon/sugar mixture.
Cool: Allow to cool on a wire rack, then enjoy.
