Preheat your oven to 200°C (390°F) and line a baking sheet with parchment paper.
In a large mixing bowl, whisk together the flour, sugar, baking powder, salt, cinnamon, ginger, and cloves for even distribution.
Add the cold, cubed butter to the dry ingredients. Use your fingers or a pastry cutter to quickly work the butter into the flour until the mixture resembles coarse crumbs with pea-sized pieces.
Stir in the pumpkin puree until just combined, then pour in the heavy cream and fold gently until the dough begins to come together. It should be slightly sticky but manageable.
Turn the dough onto a lightly floured surface. Gently knead it a few times to bring it together, then pat it into a 1-inch thick circle.
Use a sharp knife or pizza cutter to cut the dough into 8 equal wedges. Carefully transfer each wedge to the prepared baking sheet, spacing them evenly apart.
Bake in the preheated oven for 15-20 minutes, until the scones are golden brown on top and a toothpick inserted into the center comes out clean.
Remove the scones from the oven and let them cool for about 5 minutes on the baking sheet. Their edges will be crispy, and the aroma will be warm and inviting.
Serve the pumpkin cardamom scones warm or at room temperature, enjoying their tender crumb and aromatic spice notes.
