Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or a silicone baking mat.
In a large mixing bowl, whisk together the flour, sugar, baking powder, cinnamon, nutmeg, ginger, and salt.
Add the cold, cubed butter to the dry ingredients. Use a pastry cutter or your fingers to work the butter into the flour mixture until it resembles coarse crumbs.
In a separate bowl, whisk together the pumpkin puree, heavy cream, egg, and vanilla extract until well combined.
Add the wet ingredients to the dry ingredients and gently mix until the dough just comes together. Be careful not to overmix.
Turn the dough out onto a lightly floured surface and gently shape it into a circle about 1 inch thick. Cut the dough into 8 wedges and transfer them to the prepared baking sheet.
If desired, sprinkle the tops of the scones with coarse sugar for added texture and sweetness.
Bake the scones in the preheated oven for 18-22 minutes, or until they are golden brown and a toothpick inserted into the center comes out clean.
Let the scones cool for a few minutes on the baking sheet, then transfer them to a wire rack to cool completely. Serve warm or at room temperature.
Notes
For a spicier flavor, increase the amount of cinnamon or nutmeg. These scones pair wonderfully with a drizzle of maple glaze or a dollop of whipped cream.
