Prepare a container, pour lukewarm milk at 100-110ºF, add egg and sugar and mix well. Then add the yeast and stir well.
Add the flour, oil and salt and stir well with a silicone spatula to form a dough. Make sure you mix the flour until there is no dry flour left. This only takes 1 to 2 minutes.
Cover the container with a lid or cling film. Let the dough ferment until double in size, about 1 hour.
Open the lid or cling film, use a silicone spatula to fold the dough from right to left, front to back, left to right, back to front and repeat twice.
Then pour it onto the table. You must first spread a layer of flour on the table. This prevents the dough from sticking to the table.
First dust the dough and your hands with flour so that the dough doesn't stick to your hands. Then divide the dough into 8 equal pieces using a plastic dough scraper.
Shape them into rounds. Cover them with a dry cloth for about 15 minutes.
Press them on both sides with your hand and shape them into rounds again. Place them on a baking sheet or in the container you will be using. Leave them to rise for 1 hour or until they have doubled in size.
Preheat the oven to 350°F (175°C). Brush the top of the dough with milk and bake at 350°F (175°C) for 15 minutes.
Brush the milk buns with melted butter. Ready to serve.
