Preheat the oven to 400°F and line a baking sheet with parchment paper.
In a medium bowl, whisk together the flour, baking powder, cinnamon, pumpkin pie spice, and salt, then add the grated butter. Mix them well.
In the bowl of your electric mixer, beat the heavy cream, egg, pumpkin puree, brown sugar, and vanilla extract. Then add the flour mixture and beat until light and fluffy.
On a floured surface, knead the dough to become a ball, then cut the wedges into 8 using a knife (just like in the picture), and place them on a prepared baking sheet.
Bake the scones for 25-30 minutes, or until lightly brown. Allow them to cool and set them aside.
Meanwhile, melt the butter and maple syrup in a saucepan. When the butter has melted, remove it from the heat, then add the confectioners' sugar.
On baked scones, drizzle the maple syrup glaze, serve with coffee or tea, and enjoy!
