I make these often and use them for hamburgers, chicken sandwiches, and sloppy joes.  They make it all taste so much better.

1 1/4 cups milk, warm
1 egg, beaten
2 TBS butter, softened
1/4 cup sugar
3/4 tsp salt
3 3/4 cups bread flour
1 1/4 tsp active dry yeast
1 TBS butter, melted

In bread machine, place the first 7 ingredients in order listed.
Select dough setting.
When cycle is completed, turn dough onto a floured surface and punch down.
Divide dough in half.
Roll each portion to 3/4" thickness; cut with biscuit cutter.  (I use an upside down drinking glass.)
Place each bun on lightly greased baking sheets, leaving space for rising.
Brush tops with melted butter.
Cover with clean dish towel and let rise till doubled.
Bake at 350 degrees for 10-15 minutes.
