Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

In a large bowl, mix together the flour, sugar, baking powder, salt, and ground cinnamon until well blended.

Add the cold, cubed butter to the flour mixture and use a pastry cutter or your fingers to blend until it resembles coarse crumbs.

In a separate bowl, whisk together the milk, egg, and vanilla extract until well combined.

Pour the wet mixture into the dry ingredients and gently mix until just combined; avoid overmixing.

Turn the dough out onto a lightly floured surface, knead gently a couple of times, then pat it into a circle approximately 1 inch thick.

Use a knife to cut the dough into wedges or a biscuit cutter for round shapes.

Place the scones onto the prepared baking sheet and bake for 15-20 minutes, or until they are golden brown on top.

Allow the scones to cool for a few minutes on a wire rack before serving.
