In a mixing bowl add the milk and active starter, combine with a whisk or flat beaters. Add the sugar and flour, start to knead with the dough hook on speed #2 for 2 minutes. Add the salt and butter, continue to knead until the dough is smooth and elastic, approximately 7-8 minutes.
Move the dough to a lightly floured flat surface and form into a ball, place it in a lightly oiled bowl, rolling the dough to lightly cover in oil. Cover the bowl with plastic and let rise in a warm draft free area until doubled, approximately 3-4 hours.
Remove the dough and divide into 9 portions, shape each portion into a ball. Place the rolls in a lightly greased & floured square 9 inch (22 cm) pan. Cover and let rise in a warm draft free area until doubled, approximately 2 hours.
Pre-heat the oven to 350F (180C).
Brush the dough with a little milk, then bake until golden about 20-25 minutes. (Internal temperature should be about 200-205ºF (93-96ºC)). Brush the just baked buns with melted butter if desired and serve immediately or move to a wire rack to cool completely. Enjoy!
Notes
As long as you keep them tightly wrapped your homemade dinner rolls will keep for up to three days. Freeze the completely cooled buns in a freezer safe bag or container they will last up to three months in the freezer. You can also freeze the dough before baking but after the first rise. Wrap the dough in plastic, place it in a freezer safe bag or container and freeze, it will keep up to a month.
