Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
In a large mixing bowl, whisk together the gluten-free flour, baking powder, salt, garlic powder, and onion powder.
Add the cold, cubed butter to the flour mixture. Use a pastry cutter or your hands to cut the butter into the flour until the mixture resembles coarse crumbs.
Stir in the shredded cheddar cheese and chopped chives.
Pour in the buttermilk and stir until just combined. Do not overmix.
Drop spoonfuls of the dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake for 15-20 minutes, or until the biscuits are golden brown and cooked through.
Remove from the oven and let cool slightly before serving.
