Move an oven rack to the top third of your oven and preheat oven to 400℉.
In a medium bowl, whisk together the flour, baking powder and pumpkin pie spice. Add the brown sugar and mix well.
Using a pastry blender or two butter knives, add the butter to the flour mixture by cutting it in. Cut the butter until the pieces are the size of peas.
Stir the pumpkin and cream into the bowl until just combined with the flour mixture.
Flour your surface and pat the mixture into a square. Cut into 16 triangles and transfer to a baking sheet. Bake for 18-20 minutes or until the tops begin to brown.
Transfer to a cooling rack. When cooled, drizzle Pumpkin Spice Glaze over the tops of the scones.
