Preheat the Oven:
Preheat to 400°F (200°C). Line a baking sheet with parchment paper.
Mix Dry Ingredients:
In a large bowl, whisk together flour, brown sugar, baking powder, salt, cinnamon, ginger, nutmeg, and cloves.
Cut in the Butter:
Add cold butter cubes and cut in with a pastry cutter or your fingers until the mixture resembles coarse crumbs.
Mix Wet Ingredients:
In another bowl, whisk together pumpkin puree, heavy cream, egg, and vanilla.
Form the Dough:
Add wet mixture to dry ingredients. Stir until just combined (don’t overmix).
Shape and Cut:
Turn dough onto a lightly floured surface and shape into an 8-inch circle, about 1-inch thick.
Cut into 8 wedges and transfer to the baking sheet.
Bake:
Brush tops with extra cream. Bake 15–18 minutes, or until golden and firm to the touch.
Make the Glaze:
In a small bowl, whisk together powdered sugar, milk, and spices until smooth.
Glaze the Scones:
Let scones cool slightly, then drizzle with spiced glaze.
