Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper.
In a bowl, mix flour, protein powder, garlic powder, salt, and pepper.
Add yogurt, cheese, and melted butter. Stir until a sticky dough forms.
If the dough feels too dry, mix in milk a little at a time.
Scoop dough onto the baking sheet into 8 portions.
Bake 12-15 minutes or until golden brown on top.
Serve warm with butter or your favorite spread.
