01 - In a large bowl, whisk together the gluten-free flour, sugar, instant yeast, salt, and baking powder until evenly combined.
02 - Add the olive oil, warm milk, and eggs to the dry ingredients. Mix thoroughly until a soft, sticky dough forms.
03 - Cover the bowl with plastic wrap and place in a warm area. Let the 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 and tie into a loose knot. Arrange knots on prepared baking sheet.
06 - Cover knots loosely and let rest for 10 minutes before baking.
07 - Bake for 18 to 20 minutes until golden brown and cooked through completely.
08 - While knots bake, 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 garlic butter mixture. Sprinkle with Parmesan if using. Serve immediately while warm.
