Whisk the wet ingredients together: Whisk the warmed milk, condensed milk, egg, and yeast in a bowl.
Add in the dry ingredients: Add in the sifted flour, salt and sugar. Mix to combine.
Knead the dough: Use any one of the following methods to knead the dough:By hand: Turn the dough out onto a lightly floured surface. Knead for 8 to 10 minutes until the dough is smooth and elastic.By a stand mixer or a handheld mixer fitted with a dough hook for 5 to 8 minutes until smooth and elastic. Rub in the butter: Add in the butter, after the dough has been kneaded. Rub the butter into the dough and knead lightly just until combined and the dough is smooth.
Allow the dough to rise: Cover the dough with plastic wrap and leave to rise for between 45 and 60 minutes in a warm, draft-free area of your kitchen.
Punch down the dough: After the dough has risen, punch it down and turn it out of the bowl onto a well-floured surface. Knead for 1 minute. Shape the dough with your hands to form a small rectangle. This is going to make it easier for you to roll out into a rectangular shape.
Roll out the dough: Use a rolling pin to roll out the dough to approximately 12x17 inches ( 30x42cm)
Roll up and seal: Starting from the shorter side, (the side measuring 12 inches (30cm) roll up the dough tightly into a log shape.
Seal to close: Pinch the edges closed to seal. Roll the log gently with your hands to smooth out the sealed edge.
Cut the dough: Use a sharp knife to cut and divide the rolled-up dough into approximately 8 pieces about 1 ½inches (4cm) thick
Arrange pieces into a loaf baking pan: Grease and line with baking paper a large 12 x 4⅓x 3¾″ (30.5 x 11 x 9.5 cm) loaf pan OR into two standard 22 x 13 cm / 9 x 5" loaf ( 22 x 13 cm) pans.Place the pieces into the preferred pan. See note 4
Allow the cut pieces to rise for another 45 minutes: This is the second rise where the cut pieces of dough rise for another 45 minutes. The second rise is responsible for the superior flavor and texture of the bread. It allows the yeast more time to work, helping to develop a lighter, chewier texture, creating amazing flavor. Allow the shaped pieces to rise for 45 minutes covered with a cloth.
Brush with a mixture of milk and egg: Brushing with egg and milk creates a shiny and golden color of the crust. If you do not want to use an egg, just leave it out and brush it with milk instead. However, using milk on its own will not produce a shiny crust.
Bake: Preheat oven to 180°C/350°F (160°C fan oven). Bake for between 20-25 minutes until golden brown and baked through.
