In a large bowl whisk together the dry ingredients (flour, baking powder, baking soda, salt). In a separate bowl whisk together the wet ingredients (milk, butter, vinegar).
Add the wet ingredients into the dry ingredients and stir until thoroughly combined.
Separate the dough into 6 equal mounds. Drop the dough mounds onto a baking sheet at least 1 inch apart and form into round biscuit shapes about 1-inch high. Bake for 12 to 13 minutes or until lightly browned.
