Step 1

Preheat the oven to 400°F. Line a baking sheet with parchment paper.

Step 2

In a medium bowl, whisk together the pumpkin, egg, heavy cream, molasses, and vanilla. Set aside.

Step 3

In the bowl of a food processor fitted with the blade attachment, combine the flour, brown sugar, baking powder, baking soda, salt, and spices. Process for about 20 seconds to combine; be sure no lumps of brown sugar remain.

Step 4

Cut the cold butter into ½-inch chunks. Add to the food processor and pulse until the mixture resembles coarse meal – it should look unevenly crumbly with some pea-size chunks of butter within. Add the pumpkin mixture and pulse just until the mixture comes together. The dough will be very sticky, and you should still be able to see some pea-size clumps of butter.

Step 5

Lightly flour a countertop or work surface. Dump the sticky scone dough onto the floured surface and dust the top lightly with more flour. Using your hands, gently knead the dough until it comes together into a smooth ball. Divide the dough in half. Dust your work surface with flour again and form each half into a 5-inch circle, about ¾-inch thick. Using a sharp knife dusted with flour, slice each circle into 6 even wedges (cut each circle in half, then cut each half into thirds). If the dough starts to stick to the knife, dust the knife with more flour. Place the wedges on the prepared baking sheet.

Step 6

Bake the scones for 12 to 15 minutes. To see if they are done, peek at the bottoms; they should be slightly browned. Let the scones cool on the baking sheet for about 15 minutes.

Step 7

Meanwhile, make the glaze: In a medium bowl, whisk together the Confectioners' sugar, pumpkin, water, cinnamon, ginger, cloves, and nutmeg until smooth. The glaze should be thick.

Step 8

Spoon about 1 tablespoon of the glaze over each scone, letting it drip a bit down the sides. Wait about 30 minutes for the glaze to set, then serve.
