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 ingredients. Mix until a soft, sticky dough consistency forms, ensuring all flour is incorporated.
03 - Cover bowl tightly with plastic wrap. Place in a warm, draft-free area and let dough rest for 30 minutes to allow yeast activation.
04 - Preheat oven to 375°F. Line a baking sheet with parchment paper and set aside.
05 - Lightly oil hands to prevent sticking. Divide dough into 12 equal portions. Roll each piece into a 6-inch rope, then tie into a loose knot, tucking ends underneath. Arrange knots on prepared baking sheet with space between each.
06 - Cover knots loosely and let rest for 10 minutes at room temperature before baking.
07 - Place baking sheet in preheated oven and bake for 18 to 20 minutes until knots are golden brown and 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 - Remove baked knots from oven. Immediately brush generously with warm garlic butter while still hot. Sprinkle with Parmesan cheese if desired. Serve warm for optimal texture and flavor.
