In a food processor, pulse to combine the dry ingredients: gluten free flour, baking powder, sugar, and salt.
Next, cube the cold butter and add to the food processor. Pulse 12 times to turn the butter into smaller pieces.
Add buttermilk to the food processor, then pulse about 10 times until the dough comes together.
Cover a baking sheet with parchement paper or a slip mat. Use an ice cream scoop or large cookie scoop to drop the biscuit dough on the baking sheet. Using greased fingers, shape into biscuits or leave if a rustic look is desired.
Bake for 20-25 minutes or until the tops are golden brown.
