In a mixing bowl or using a stand mixer with dough hook, combine flour with baking powder, salt, garlic, basil, pepper and mix to combine. Add greek yogurt and egg and mix until you have a shaggy ball of dough. Flour the outside to make it easier to work with and flour your surface/hands as needed.
Divide dough into 12 even pieces. Roll each piece into a ball and, on a well floured surface, roll the ball out to roughly 2 inches in diameter and fill the outer edges of the muffin pan with it.
Spray with cooking spray and bake until lightly golden, 15-18 minutes.
Fill each cup with a little sprinkle of cheese to create a base. Then fill with 1/2 tbsp pizza sauce and top with 1 tbsp of cheese. Add any toppings desired and bake for an additional 5-8 minutes, until cheese is melted.
