Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper. This will ensure that your scones bake evenly and don't stick.
In a large mixing bowl, whisk together the all-purpose flour, dark brown sugar, baking powder, ground cinnamon, ground ginger, and ground cloves. Make sure everything is well combined.
Add the chilled butter pieces to the dry mixture. Using a pastry cutter or fork, cut the butter into the flour mixture until it resembles coarse crumbs.
In a separate bowl, whisk together the milk, egg, molasses, and vanilla extract until well combined.
Pour the wet ingredients into the bowl with the dry ingredients. Stir gently with a spatula or wooden spoon until just combined. Be careful not to overmix; it’s okay if there are a few lumps.
If you’re using raisins or dried cranberries, gently fold them into the dough at this stage.
Turn the dough out onto a floured surface and pat it into a circle about 1-inch thick. Cut the circle into wedges (like a pizza) or use a biscuit cutter to create round scones.
Place the scones on the prepared baking sheet. If desired, sprinkle coarse sugar on top for added sweetness and crunch.
Bake in the preheated oven for about 15-20 minutes, or until the scones are golden brown and a toothpick inserted into the center comes out clean.
Remove the scones from the oven and let them cool on the baking sheet for a few minutes before transferring them to a wire rack. Serve warm with butter or your favorite jam.
