01 - In a large bowl, whisk together the gluten-free flour, sugar, instant yeast, salt, and baking powder until thoroughly combined.
02 - Add the olive oil, warm milk, and eggs to the dry mixture. Mix until a soft, sticky dough comes together.
03 - Cover the bowl with plastic wrap and let the dough rest in a warm place for 30 minutes to hydrate.
04 - Preheat oven to 375°F and line a baking sheet with parchment paper.
05 - Lightly oil your hands to prevent sticking. Divide the dough into 12 equal pieces. 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 and let rest for 10 minutes before baking.
07 - Bake for 18 to 20 minutes, or until knots are golden brown and cooked through.
08 - While knots bake, melt the 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 the hot knots generously with garlic butter. Sprinkle with Parmesan if using. Serve immediately while warm.
