In a large bowl, mix the flour, baking powder, spices, and salt.
Add the coconut oil, pumpkin puree, milk, and maple syrup. Mix well.
Prepare a baking sheet with baking paper or a silicone mat. Put the mix on it and form a disk.
With a chef's spatula or a large knife, divide the dough disc into eight pieces.
Bake for 18-20 minutes or until you insert a toothpick and it comes out clean.
Meanwhile, in a separate bowl, mix the confectioners' sugar, maple honey, and spices to prepare the glaze. If the mixture is too thick, add water slowly, one teaspoon at a time.
Remove the scones from the oven and let them cool for about 5 minutes. Pour the icing on top of the scones and sprinkle with the chopped walnuts.
