Take the butter straight from the fridge and grate it on the large holes of a box grater. Stick it back in the fridge while you prepare the other ingredients.
In a bowl, whisk together the all-purpose flour, baking powder, baking soda, sugar, salt, cinnamon, ginger, nutmeg, allspice, and cloves (or pumpkin spice).
In another bowl, mix together the cream, sour cream, pumpkin puree, and maple syrup until well combined.
Take the grated butter from the fridge and mix it with the dry ingredients.
Add the wet ingredients to the dry ingredients and mix until just combined. Be careful not to overmix. The mixture should form a slightly sticky dough with small chunks of butter.
Lay out a sheet of plastic wrap and shape the dough into a rectangle about 1 inch (2.5cm) thick. Wrap the dough tightly in the plastic wrap and refrigerate for at least 2 hours.
Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
Remove the chilled dough from the refrigerator and cut it into your desired scone shapes. For best results, freeze the shaped scones for at least 2 hours before baking. This will help them retain their shape.
Place the frozen scones on the prepared baking sheet. Brush the tops with cream.
Bake the scones in the preheated oven for 15-18 minutes or until they turn golden brown.
While the scones are cooling, prepare the maple glaze. In a bowl, mix powdered sugar with maple syrup. Adjust the amount of maple syrup based on the desired consistency of the glaze. Stir until smooth.
Once the scones have cooled, drizzle the maple glaze over the top of each scone.
Enjoy!
