Pre-heat oven to 400F.

Combine flour, cinnamon, brown sugar,baking powder and baking soda in a bowl. Add the cold butter and with a fork combine it with the flour so that it looks a little crumbly.

In a separate bowl combine the egg yolk, buttermilk. Add it to the dry ingredients when combined add the cinnamon chips, gently knead it all together forming a ball of dough.

Shape into a flat circle on a greased cookie sheet and cut the dough into wedges.

Bake for about 12 minutes.

Make the maple glaze: Whisk the powdered sugar, maple syrup, milk and vanilla in a bowl. If the glaze is a little too thick when you lift the whisk and doesn't come off easily, add a little more milk, however if it's a little too runny, add more powdered sugar.

Drizzle over the scones. Serve warm.
