Step 1: Preheat your oven to 425°F (220°C) to ensure perfect rising.
Step 2: In a large mixing bowl, whisk together the flour, salt, sugar, and baking powder until evenly mixed.
Step 3: Cut the cold butter into the flour mixture using a pastry cutter or fork, until it resembles coarse crumbs.
Step 4: Make a well in the center and pour in the buttermilk, stirring gently until the dough comes together.
Step 5: Turn the dough out onto a floured surface and knead gently about 3-4 times.
Step 6: Roll the dough to 1-inch thickness and cut out biscuit shapes with a cookie cutter.
Step 7: Bake in the preheated oven for 12-15 minutes until golden brown.
Step 8: Let cool slightly on a wire rack and serve warm.
