Activate the yeast by mixing warm water with sugar and yeast in a bowl. Let sit for 5 minutes until frothy.

In a large bowl, whisk together flour and salt.

Combine softened butter and eggs with the yeast mixture, then pour into the dry ingredients and mix until combined.

Knead on a floured surface for about 8-10 minutes until smooth.

Place dough in a greased bowl, cover with a damp cloth, and let rise in a warm spot until doubled in size (about 1 hour).

Punch down the dough, divide into equal pieces, shape into balls, and place on parchment-lined baking sheets.

Cover shaped buns and let them rise again for about 30 minutes.

Preheat oven to 375°F, brush buns with an egg wash, and bake for about 15 minutes until golden brown.
