01 - Combine oats, all-purpose flour, kosher salt, and instant yeast in a large mixing bowl. Stir thoroughly to blend.
02 - In a separate bowl, whisk together warm milk, molasses, melted butter, and egg until smooth.
03 - Pour the wet mixture into the dry ingredients. Mix with a wooden spoon or spatula until a sticky dough forms.
04 - Turn the dough onto a floured surface and knead for 8 to 10 minutes until smooth and elastic. Optionally, use a stand mixer fitted with a dough hook for 6 to 8 minutes.
05 - Transfer the dough to a lightly greased bowl. Cover with a kitchen towel and let rise in a warm place for 1 hour or until doubled in size.
06 - Punch down the dough and divide evenly into 12 portions. Shape each portion into a round roll. Place rolls on a parchment-lined or greased baking sheet, spaced slightly apart.
07 - Cover the rolls loosely and let rise until puffy, approximately 30 minutes. Preheat oven to 375°F.
08 - Brush the roll tops with milk or melted butter as desired and sprinkle with additional oats.
09 - Bake for 22 to 25 minutes until golden brown. Transfer rolls to a wire rack to cool slightly before serving.
