01 - Whisk together the gluten-free flour, sugar, instant yeast, salt, and baking powder in a large mixing bowl until thoroughly combined.
02 - Add the olive oil, warm milk, and eggs to the dry ingredients. Mix until a soft, sticky dough forms and all flour is incorporated.
03 - Cover the bowl with plastic wrap and place in a warm area. Let the dough rest for 30 minutes to hydrate and relax.
04 - Preheat oven to 375°F and line a baking sheet with parchment paper.
05 - Lightly oil your hands to prevent sticking. 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.
06 - Cover the knots loosely and let rest for 10 minutes before baking.
07 - Bake for 18 to 20 minutes until golden brown and fully cooked through.
08 - While knots are baking, melt butter in a small saucepan over medium heat. Add minced garlic and cook for 1 minute until fragrant. Remove from heat and stir in parsley, salt, and pepper.
09 - Brush hot knots generously with the garlic butter mixture. Sprinkle with Parmesan cheese if using. Serve warm.
