Preheat oven to 425°F (220°C) and line a baking sheet with parchment paper.
In a bowl, whisk together flour, baking powder, baking soda, garlic powder, and salt.
Cut in butter using a pastry cutter or fork until the mixture resembles coarse crumbs.
Add cheese, then stir in buttermilk until a sticky dough forms.
Drop spoonfuls of dough onto the prepared baking sheet, spacing evenly.
Bake for 12–14 minutes, until golden brown.
Brush tops with garlic butter mixture while warm.
Let rest for 5 minutes, then serve warm.
