Preheat oven to 400° (F)
Sift or whisk together the flour, sugar, baking powder and salt.
Add cold butter (160 g) to the dry ingredients and, using a pastry blender or your hands, work butter into the dry ingredients. Continue to work the butter until there are still bits of butter about the size of a pea.
Add 10 fluid ounces (1 ¼ cup) of heavy cream to the bowl and toss with a rubber spatula. Work dough briefly with your hands until it starts to come together.
Lightly flour a work surface and place dough on the work surface. Knead briefly until no dry crumbs remain.
Roll dough to ½ inch (dust worksurface and/or rolling pin with flour if the dough begins to stick).
Cut biscuits using a 3" round pastry cutter.
Roll out remaining scraps of dough and cut additional biscuits.
Place half of the biscuits on a baking pan lined with parchment paper (or a Silpat or lightly butter the pan).
Brush the tops of the biscuits lightly with melted butter. Place the other half of the biscuits on top of the biscuits in the pan and brush lightly with melted butter.
Bake at 400° F for 12 - 15 minutes. Biscuits will be well risen and a dark brown when finished.
Cool biscuits completely before assembling the shortcakes.
