In a large bowl, stir together the flour, brown sugar, baking powder and salt.
Using a pastry blender or just your hands, cut the shortening into the flour mixture until the mixture is coarse and crumbly.
Add in the buttermilk and honey, and stir together until a dough forms. Turn the dough out onto a floured surface, and pat into a long rectangle.
Fold the dough into thirds, and pat out to a rectangle about 3/4 inch thick. Using a 2.5 inch cutter, cut out your biscuits. You can re-use the dough scraps once.
Place the biscuits onto a lined baking sheet, and place in the fridge for 20 minutes.
While the biscuits chill, preheat your oven to 400 degrees, and mix the butter and remaining brown sugar together.
Brush the tops of the biscuits with the butter and brown sugar mixture, and bake for 13-15 minutes, or until the biscuits are puffed and golden brown on top.
Serve warm, with honey and jam or butter!
