I used a bread machine for this recipe. You could also use a hand mixer for the following steps. you can use a stand mixer and follow the steps.
Into a small bowl add yeast, 2 teaspoons of sugar, and ½ cup of warm water. Let it rise for 15 minutes.
2 tsp yeast, ⅓ cup sugar, 1½ cups warm water
In bread machine bowl add the rest of the sugar and warm water. Combine with the rest of the ingredients.
⅓ cup sugar, 1½ cups warm water, 2 large eggs, ½ cup unsalted butter,, ¼ cup warm milk,, 1 tsp salt, 5 cups unbleached flour,
Turn on the DOUGH setting on your bread machine, and let it do the job. My bread machine takes 2 hours and 20 minutes. This can vary depending on your machine.
Spray a rectangular 18″ X 13″ baking sheet. (If your pan is not a nonstick type, then you should put a sheet of parchment paper.)
The dough will be easy to work with. Use unbleached flour to form the dough into 24 balls and lay them on the baking sheet.
Let rise for 35 minutes.
Preheat the oven to 360F.
For the nice golden color of the soft buns, whisk 1 large egg and brush on the tops of the buns.
1 large egg,
Place in the oven for 20 minutes.
Let it cool down and enjoy!
