In the bowl of a stand mixer fitted with the paddle attachment, combine warm milk, sugar, and yeast. Let stand until mixture is foamy, about 10 minutes.
With mixer running on low speed, add 1 cup (125 grams) flour, beating just until combined. Add melted butter and ½ cup (63 grams) flour, beating until combined. Beat in eggs. Gradually add salt and remaining 1¾ cups (218 grams) flour, beating until a soft dough forms. (Dough will be sticky.)
Spray a large bowl with cooking spray. Place dough in bowl, turning to grease top. Loosely cover and let rise in a warm, draft-free place (75°F) until doubled in size, about 1 hour.
