Preheat the oven to 400°F. Line a baking sheet with parchment paper or grease a scone pan if using
In a medium bowl, whisk together the pumpkin, egg, coconut milk, maple syrup and vanilla. Set aside.
In the bowl of a food processor fitted with the blade attachment, combine the flours, baking powder, baking soda, salt and pumpkin spice mix. Process to combine.
Cut the cold butter into 1/2-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.
If using scone pan divide batter evenly and press into compartments. If forming by hand lightly flour a countertop or work surface with coconut flour. 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 coconut flour again and form each half into a 5-inch circle, about 3/4-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.
Bake the scones for 12-15 minutes. To see if they are done, peek at the bottoms; they should be slightly browned but not burnt. Let the scones cool on the baking sheet for a few minutes, then transfer to a wire rack to cool completely.
