Preheat your oven to 450°F (230°C). Line a baking sheet with parchment paper. This prevents sticking and helps biscuits bake evenly. Set aside while you prepare the dough.

In a large mixing bowl, whisk together flour, baking powder, salt and sugar. Make sure everything is evenly combined for consistent biscuits.

Add cold butter cubes to the dry mixture. Use a pastry cutter or your fingers to mix until it looks like coarse crumbs. Keep butter cold for fluffy biscuits.

Pour cold milk into the flour and butter mixture. Stir gently with a spatula or spoon until a soft dough forms. Do not overmix, or biscuits become tough.

Place dough on a lightly floured surface. Fold and press the dough 3–4 times until it holds together. Avoid heavy kneading to keep biscuits soft and airy.

Roll dough to about ½-inch thickness. Use a biscuit cutter or glass to cut circles. Re-roll scraps to make more biscuits. Keep edges clean for even rising.

Place biscuits on prepared baking sheet, leaving small gaps. This allows them to bake evenly and rise without sticking together.

Bake in preheated oven for 12–15 minutes. Biscuits should be golden brown on top. Check with a toothpick if unsure.

Remove biscuits from oven and brush with melted butter. This adds flavor and gives a shiny, appetizing look. Serve warm for best taste.
