Grate the cold butter into the dry ingredients and mix everything with your hands making sure the butter is distributed evenly.
1/3 cup unsalted butter
Add the wet ingredients including the vanilla extract and cold liquid whey. Loosely bring the dough together with a spoon. Don't over-mix it. You're after a very rough dough, not a smooth one.
1 1/4 cup liquid whey, 1 tsp vanilla extract
Add the scone dough onto a lightly floured surface and form a 1-inch thick circle or square with your hands or a rolling pin. Cut the scones into round shapes with a cookie cutter or scone cutter (approx. 4-inch diameter). Alternatively, you can shape them into squares or triangles with a pastry cutter or sharp knife.
Place them onto a parchment paper lined baking tray side by side as you want them to rise up instead of spreading out. Brush the top of the scones with milk (or use an egg wash) and bake the scones in the oven for 13 minutes or until you can spot a golden-brown crust.
1 tbsp milk
Notes
Don't over-mix the dough or the scones will be tough and chewy.Make sure the butter is cold to be able to grate it. On hot days you can pop it into the freezer for 5 minutes before grating to prevent it from softening too quickly.Place the scones side by side when baking which helps them rise up instead of out.The scones need a short time in a hot oven. Ensure the oven is up to temperature before baking them.Storage: Scones last 3-4 days in an airtight container at room temperature. Simply reheat them in a microwave or oven before serving. You can also freeze baked and even unbaked scones in a freezer-proof container for up to 3 months.
