Instructions:
In a large mixing bowl, combine the lukewarm milk and softened butter. Stir until the butter is melted and well incorporated into the milk.
Add the bread flour, sugar, salt, and instant yeast to the bowl. Mix with a flexible spatula until the ingredients are combined and a sticky dough forms.
Transfer the dough to a floured surface and knead for about 8-10 minutes, until it becomes smooth and elastic. Alternatively, you can use an electric stand mixer with a dough hook for this step.
Place the kneaded dough in a greased bowl, cover it with a clean kitchen towel, and let it rise in a warm, draft-free area for about 1 hour or until it has doubled in size.
Once the dough has risen, punch it down to release the air. Shape it into a loaf and place it in a greased 9x5 bread pan. Cover with the kitchen towel and let it rise again for 30-45 minutes until it has puffed up.
Preheat your oven to 375°F (190°C). Once the dough has finished rising, bake it in the preheated oven for 40-60 minutes, or until the top is golden brown and the bread sounds hollow when tapped.
Remove the bread from the oven and let it cool in the pan for about 10 minutes. Then transfer it to a wire rack to cool completely before slicing.
