Preheat the oven to 350ºF and line a large baking sheet with parchment paper or a silicone liner. In the bowl of a large food processor fitted with an "S" blade, process together the flour, sugar, and coconut oil until crumbly. Add in the pumpkin, cinnamon, ginger, cloves, salt and baking soda and process again until a thick dough is formed. Add in the vinegar last, and process once more to incorporate it thoroughly.
Use a heaping 1/4 cup to scoop the dough and drop it into 8 evenly-sized mounds on the lined baking sheet. Bake until the centers of the scones are firm to the touch and your kitchen is filled with a fragrant Fall scent, about 20 minutes. Allow the scones to cool completely before topping with the Creamy Maple Glaze.
To prepare the glaze, stir together the cashew butter, arrowroot, maple syrup and 2 teaspoons of water. Add more water if needed to thin, then spoon the glaze over each scone and serve. Thanks to the use of arrowroot, this glaze will "set" to an extent, similar to a glaze made with powdered sugar, after a few hours. (I noticed the glaze was dry to the touch after 4 hours.)
These scones can be stored at room temperature for up to 3 days, or in the fridge for up to one week.
