Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper. Set aside.
In a large mixing bowl, sift together the flour, baking powder, cinnamon, nutmeg, ginger, and cloves. Whisk to combine.
Add the cold cubed butter to the dry mix. Use a fork (or pastry cutter) to incorporate the butter into the flour until the mixture resembles coarse sand with some pea-sized pieces remaining.
In a separate bowl, whisk the pumpkin puree, egg, milk, vanilla extract, and sugar.
Pour the wet ingredients into the dry mixture. Use a spatula or wooden spoon to gently bring the dough together. If the dough feels too sticky, sprinkle in a bit more flour, one tablespoon at a time, until manageable.
Turn the dough onto a lightly floured surface. Pat it into a 6-7 inch circle. Use a pizza cutter or sharp knife to cut circle into 8 wedges. Transfer scones to the prepared baking sheet, spacing them slightly apart.
Bake for 15–18 minutes, or until the tops look set and edges are lightly golden. Cool completely before glazing.
Vanilla Glaze: Whisk the powdered sugar, cream, and vanilla extract until smooth. Spoon or brush the mixture over the cooled scones to coat the surface.
Pumpkin Drizzle: In another bowl, whisk all the ingredients for the pumpkin drizzle. Start with 1 tablespoon milk and add more as needed for a thick, drizzly consistency. Drizzle the scones with the pumpkin glaze once the base has set. Serve & enjoy!
