Combine Dry Ingredients: In a large bowl, whisk flour, baking powder, baking soda, salt, and garlic powder.
Add Butter: Use a pastry blender or fingers to cut butter into flour until mixture is crumbly.
Add Cheese & Buttermilk: Stir in cheese and chives, then add buttermilk, mixing until just combined.
Shape Biscuits: Turn dough onto a floured surface. Pat to 1 inch thick, fold in thirds, flatten, and repeat. Cut into rounds without twisting cutter.
