Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, cinnamon, nutmeg, ginger, and salt until well combined.
Add the cold, cubed butter to the dry ingredients. Using a pastry cutter or a fork, cut 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 smooth.
Pour the wet ingredients into the dry ingredients and gently fold with a rubber spatula until just combined. Be careful not to overmix.
Turn the dough out onto a lightly floured surface and gently knead it a few times until smooth. Pat the dough into a 1-inch thick round or rectangle.
Cut the dough into 8 equal triangles or use a biscuit cutter to make rounds. Place the scones on the prepared baking sheet.
Bake in the preheated oven for 15-20 minutes, or until the scones are golden brown and a toothpick inserted into the center comes out clean.
Allow the scones to cool slightly on the baking sheet before transferring them to a wire rack to cool completely.
For added sweetness, consider drizzling a maple glaze over the scones after they have cooled.
