Pre-heat oven to 375 F.

In a bowl add flour, baking powder, salt and sugar and mix well.

Cut cold butter into chunks and add to flour and mix with hands or a pastry cutter into flour until you have pea sized butter chunks.

Mix milk and vinegar together and let sit for 1 minute then add to the flour and butter mixture and stir until a dough forms. The less you mix this dough the better your layers will be.

Flour a surface and roll dough out to about 3/4 to 1 inch thickness and use a round cookie cutter to make round biscuits.

Place on a parchment paper lined cookie sheet and brush tops with milk or cream for a golden top.
