Preheat oven and mix flour, salt, garlic powder and yogurt until there's no crumbles left in the bottom of the bowl, sides of bowl are mostly “clean” and the dough looks well combined.
Lay out dough on floured surface. Pat out the dough until it's about ½ inch thickness. Using a biscuit cutter (sprayed for non stick cooking spray) cut out 9 biscuits.
