Preheat your oven to 425 degrees Fahrenheit now. Line a baking sheet with some parchment paper. This will keep the biscuits from sticking.

In a large bowl, whisk the flour and sugar. Make sure they are mixed well together. This ensures a consistent taste in every bite.

Add the cold butter and shortening to flour. Use your pastry cutter to mix them in. The mix should look like small peas.

Make a small well in the center now. Pour the cold buttermilk into that well. Stir gently until a soft dough forms.

Place the dough on a floured surface carefully. Fold the dough over about five times. This step creates the famous flaky layers.

Roll the dough to one inch thick now. Use your biscuit cutter to press straight down. Do not twist the cutter while working.

Remove them when the tops are golden brown. Brush the tops with melted butter immediately. Serve them while they are still hot.
