Mix flour, baking powder, baking soda, and salt together.
Cut butter into sixteen, tablespoon slices. Add butter to dry ingredients. Using your hands, mix the butter in with the flour mixture. Your goal is to get flakey pieces of dough. Use your fingers to gently break up the bigger clumps.
Add one cup of milk. Mix together using your hands. Then add additional 1/2 cup of milk. If dough is still too dry, add another 1/4 cup of milk. The goal is to get a somewhat sticky, bulky dough.
Pre-heat oven to 400 degrees.
Flour surface and your hands.
Gently place the dough on the floured surface. Mash flat with hands until dough is about 1/4 inch thick. You may need to sprinkle a little flour on top of the dough to keep from sticking to your hands.
Cut out biscuits using a biscuit cutter or glass mason jar. (I use a jelly jar.) Once you have cut out all the biscuits you can, re-gather remaining dough and follow step 6 until all the dough is used.
Lightly spray a cookie sheet or cast iron skillet with cooking spray or coat with a thin layer of oil.
Bake for 15-20 minutes or until golden brown.
