In a cold/chilled bowl, add the flour, baking powder, sugar and salt. Stir to incorporate the ingredients.
Don't forget the baking powder or they won't rise!
Make sure your butter is cold and cut into small cubes and cut it into your dough. You'll want it to break into smaller pieces so you make little butter pockets. They will melt and make your biscuits fluffy!
Use a fork, pastry cutter or your hands to make the butter small. I prefer to use my hands and press the butter flat and incorporate into small pieces with the flour.
Add the buttermilk and mix with a fork. You will eventually need to get your hands in to mix. Add more buttermilk if it is a little dry. You'll want it a little sticky, but not so sticky it doesn't form biscuits.
Place the dough on a lightly floured surface. Hand press the dough out into a rectangle.
You will want to fold the dough onto it's self into thirds (side to side and then top to bottom). Add more flour if the dough sticks to the counter.
Press out the dough gently and then repeat the folding 2 more times. You are creating flaky layers!
Once you have made layers, use a rolling pin and roll the biscuits out to 1" thickness.
You will want to use your cutter and press into the dough...but don't turn it! Turning it causes the edges to seal....and no flaky layer goodness.
Place onto your baking sheet (we use parchment paper) and bake for 10-15 minutes.
Remove from the oven and they should golden brown on the top and fluffy.

Notes
Some recipes use baking soda and baking powder. This buttermilk biscuit recipe does not need baking soda.
