Activate the Yeast:
In a small bowl, combine the warm water and sugar. Sprinkle the yeast over the top and stir gently. Let it sit for about 5-10 minutes until the mixture becomes bubbly and foamy.

Mix the Dough:
In a large mixing bowl, combine the flour and salt. Pour in the yeast mixture and softened butter. Stir until the dough begins to form.

Knead the Dough:
Turn the dough out onto a floured surface and knead for about 8-10 minutes until the dough becomes smooth and elastic. If the dough is too sticky, add a small amount of flour at a time as needed.

Let the Dough Rise:
Place the dough in a greased bowl and cover with a clean towel. Let it rise in a warm place for about 1 hour, or until it has doubled in size.

Shape the Dough:
After the dough has risen, punch it down gently and turn it out onto a floured surface. Shape it into a loaf and place it in a greased 9×5-inch loaf pan.

Second Rise:
Cover the loaf pan with a towel and let the dough rise for an additional 30 minutes, or until it has risen just above the top of the pan.

Bake:
Preheat your oven to 375°F (190°C). Once the dough has finished rising, place it in the oven and bake for 25-30 minutes or until the top is golden brown and the loaf sounds hollow when tapped on the bottom.

Cool and Serve:
Remove the bread from the oven and let it cool on a wire rack before slicing. Enjoy your homemade white bread!
