Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a large bowl, whisk together flour, sugar, baking powder, salt, and cinnamon.
Cut in the butter until the mixture resembles coarse crumbs.
Stir in the cinnamon chips.
In a small bowl, whisk together the cream, egg, and vanilla.
Add the wet ingredients to the dry ingredients and stir until just combined.
Turn the dough out onto a floured surface and knead gently.
Pat the dough into a circle about 1 inch thick. Cut into 8 wedges.
Place the wedges on the prepared baking sheet.
Bake for 18-20 minutes, or until golden brown.
