1. Preheat oven to 425 degrees F. Line a large baking sheet with parchment paper or a Silpat and set aside.

2. In a large bowl, whisk together flour, baking powder, sugar, cinnamon, and salt. Quickly cut in the butter, using your hands, two knives, or a pastry blender. Mix until mixture resembles coarse meal, with a feel larger butter lumps. Stir in the cinnamon chips. Pour heavy cream over the ingredients and stir with a spatula until dough begins to form. Don't over mix.

3. Transfer dough to a floured countertop and knead dough by hand just until it forms a ball. Form scones by patting the dough into a 3/4-inch thick circle. Cut the scones into triangles or use a biscuit cutter. Press scraps back together and cut additional scones until dough is used up.

4. Place scones on prepared baking sheet. In a small bowl, combine sugar and cinnamon. Using a pastry brush, brush scones lightly with heavy cream. Sprinkle scones with cinnamon/sugar mixture. Bake scones for 12-15 minutes, or until scones are light brown. Cool scones on a wire cooling rack and serve.

Scones will keep in an air-tight container for up to 2 days, but they really are best eaten the day they are made.
