Preheat oven to 400 F (200 C). Line baking sheet with parchment paper.
In a large bowl, combine flour, baking powder, sugar, salt, garlic powder, smoked paprika, and chives.
Chop 6 tablespoon of chilled butter into small cubes, reserve the remaining 2 Tbsp.
Cut chopped butter into dry ingredients using a fork (or two!) or a pastry blender / cutter until mixture is distributed throughout, and mixture resembles gravel.
Add cheese, stir until combined.
Whisk egg into buttermilk. Add egg mixture to dry ingredients, stir JUST until combined - mixture will be a little sticky.
Turn dough out onto a floured surface, sprinkling some flour on top. Gently knead for a few seconds, then gather dough up into a ball.
Press down to a disk that’s an even 1" thickness, cut into 6 wedges.
Transfer scones to prepared baking sheet.
Melt reserved butter, brush about half of it onto scones.
Bake for about 22-25 minutes or until golden brown.
If you’d like, immediately brush the remaining butter over the hot scones, for extra richness.
Notes
* If you don’t have buttermilk, measure 2 teaspoon of lemon juice into your measuring cup, and top with milk to the 1 cup line. Let it sit a few minutes before using.
