Preheat the oven to 400F. Line a baking sheet with parchment paper. Set aside.
Combine the all-purpose flour, baking powder, salt, ginger, cinnamon, cloves and brown sugar in a food processor.
Pulse to combine the dry ingredients together.
Add the cold butter chunks to the food processor.
Pulse food processor about 20 times, until mixture resembles coarse crumbs with butter pieces no larger than the size of small peas. If you don’t have a food processor, use a pastry blender or two knives to cut the butter into the flour.
Pour the mixture into a bowl. Then, add the molasses and milk. Stir until the dough forms a ball.
Roll the scone dough into a 9-10 inch circle on a floured or non-stick surface, such as parchment paper.
Cut into 8 equal wedges. Place the wedges on a parchment lined baking sheet, leaving a few inches in between each wedge to allow them to spread a little while baking.
Bake the scones at 400F in the center rack of the oven for 15 minutes, until the scones are golden on the edges.
Remove from the oven and let cool on a wire cooling rack.
While the scones cool, combine the powdered sugar, maple syrup, melted butter, and vanilla in a small bowl. Add just enough milk to get a smooth glaze. Drizzle the maple glaze over the scones.
