01 - In a stand mixer bowl, combine flour, sugar, yeast, and salt. Mix briefly to distribute evenly.
02 - Add eggs and lukewarm milk to the dry ingredients. Mix on low speed until a rough, shaggy dough forms.
03 - With mixer on medium speed, add butter cubes one at a time, waiting for each piece to fully incorporate before adding the next. Continue kneading for 8–10 minutes until dough is smooth, shiny, and elastic.
04 - Transfer dough to a lightly greased bowl. Cover with plastic wrap or damp towel. Let rise in a warm, draft-free place for 1 to 1.5 hours until doubled in size.
05 - Punch down risen dough to release air. Divide into 12 equal portions. Shape each piece into a smooth, tight ball by tucking edges underneath.
06 - Arrange dough balls in a greased 9x13-inch baking pan or on a lined baking sheet, leaving slight space between rolls. Cover and let rise for 45–60 minutes until puffy and nearly doubled.
07 - Preheat oven to 350°F.
08 - Whisk together egg and milk for egg wash. Gently brush the tops of risen rolls with the mixture, avoiding excess pooling.
09 - Bake for 18–22 minutes until deep golden brown and rolls sound hollow when tapped lightly. Internal temperature should reach 190°F.
10 - Let rolls cool in pan for 5–10 minutes before transferring to a wire rack. Serve warm or at room temperature.
