In a small saucepan over medium heat or in a microwave-safe bowl, heat the butter until melted. Add the milk and stir to combine. Remove from heat and let cool until lukewarm (100 to 110°F).

In the bowl of a stand mixer, combine the milk mixture, two eggs, sugar, salt, and yeast. Add about half of the flour and stir with a wooden spoon until a rough, shaggy dough forms. Attach the dough hook to the mixer, turn to medium-low speed, and gradually add the remaining flour, kneading until a cohesive dough begins to form. Increase to medium-high speed and knead for 7 to 8 minutes until a soft and smooth dough ball is formed.

Lightly spray a large, clean bowl with cooking spray. Place the dough in the bowl, cover the bowl lightly with plastic wrap, and let rise at room temperature until doubled in size, about 90 minutes***.

Punch down the risen dough and turn out onto a clean work surface. Use a bench scraper to divide into 15 equal pieces (about 70 grams each). Roll each piece into a ball, then into a 9-inch-long rope. Tie each rope into a knot, tucking the ends in, and place into the prepared pan. Repeat for all knots.

Cover loosely and let rise until puffy and nearly doubled in size, about 45 minutes to 1 hour. The dough is ready when a light press with your finger leaves a small indentation.

While the knots rise, make the garlic butter. In a small saucepan over medium-low heat, melt the butter. Add the garlic and cook, stirring often, until fragrant, about 1 to 2 minutes. Stir in the parsley, garlic powder, and salt. Remove from heat.

Preheat the oven to 400°F.

While still warm, brush generously with garlic butter mixture—it may seem like a lot, but let it soak into every crevice for maximum flavor. If you have any leftover garlic butter, give the knots another brush. Sprinkle with flaky sea salt and Parmesan cheese. Serve warm with marinara sauce, if desired.
