01 - Whisk together gluten-free flour, sugar, instant yeast, salt, and baking powder in a large mixing bowl until thoroughly combined.
02 - Add olive oil, warm milk, and eggs to the dry mixture. Mix vigorously until a soft, sticky dough consistency is achieved.
03 - Cover the bowl tightly with plastic wrap. Place in a warm, draft-free area and let dough rest for 30 minutes to hydrate.
04 - Preheat oven to 375°F. Line a baking sheet with parchment paper and set aside.
05 - Lightly coat hands with oil. Divide dough into 12 equal portions. Roll each piece into a 6-inch rope and tie into a loose knot. Arrange knots on the prepared baking sheet with spacing.
06 - Cover the shaped knots and allow to rest at room temperature for 10 minutes before baking.
07 - Bake for 18 to 20 minutes until knots develop a golden-brown color and are fully cooked through.
08 - While knots bake, melt butter in a small saucepan over medium heat. Add minced garlic and sauté for 1 minute until fragrant. Remove from heat and stir in parsley, salt, and pepper.
09 - Immediately brush hot knots generously with the prepared garlic butter mixture. Sprinkle with Parmesan cheese if desired. Serve warm.
