In a large bowl, thoroughly mix 2 cups flour, sugar, salt and yeast. Add softened butter.

Gradually add very hot tap water to bowl with mixer on medium speed. Beat 2 minutes.

Add 1 cup flour or enough to make a thick batter. Beat at high speed for 2 minutes. Scrape bowl occasionally. Stir in cheese and onion and enough additional flour to make a soft dough. Knead on floured board 8-10 minutes. (I use the mixer dough hook for 4 to 6 minutes.)

Place in greased bowl, turning to grease top of dough, cover with damp cloth and let raise about 1 hour.

Punch dough down; turn out onto lightly floured board, divide dough into 20 equal pieces. Form each into smooth ball. Place 2 inches apart on greased baking sheets. Cover (I don’t) and let raise until doubled, about 45 minutes.

Bake in hot oven 400° for 15 to 20 minutes.

Cook on wire racks.

Note: Add 1 Tbsp dough enhancer (optional).
Note: For soft tops, brush with melted butter.
Note: Makes 20 – 2.1 oz buns (approximately).
