Preheat your oven to 400°F (200°C).
In a mixing bowl, combine 1 cup of all-purpose flour, 2 teaspoons of baking powder, and 1 teaspoon of salt. Mix well.
Add 1 cup of Greek yogurt to the dry ingredients and mix until a dough forms.
Knead the dough on a floured surface for about 1 minute until smooth.
Divide the dough into 8 pieces, roll each into a rope, and tie into a knot.
Mix melted butter and crushed garlic in a small bowl.
Brush garlic butter over each knot and bake for 12-15 minutes until golden brown.
Serve warm with marinara sauce or your favorite dipping sauce.
