Preheat the oven to 400°F (200°C).

Line a baking sheet with parchment paper.

In a large mixing bowl, whisk together the flour, granulated sugar, baking powder, salt, and ground cinnamon.

Add the cold, cubed butter to the flour mixture and mix until the mixture resembles coarse crumbs.

In a separate bowl, combine the milk and vanilla extract.

Pour the wet ingredients into the dry mixture and stir gently until just combined.

In a small bowl, mix the brown sugar and ground cinnamon for the filling.

Roll out the dough into a rectangle, sprinkle the filling evenly, and fold it over to create layers.

Roll the dough into a circle about 1 inch thick and cut into triangles or desired shapes.

Place the cut scones on the prepared baking sheet.

Bake for 15 minutes or until golden brown.
