1. In a mixing bowl, whisk together the flour, sugar, salt, and instant yeast.

2. In another bowl, whisk together the sweetened condensed milk, warm milk, melted butter, and egg until smooth.

3. Gradually add the wet mixture to the dry ingredients, stirring until a soft dough forms. Knead on a lightly floured surface for 10–15 minutes until smooth and elastic.

4. Place the dough in a greased bowl, cover with a kitchen towel, and let rise in a warm spot for about 1 hour or until doubled in size.

5. Punch down the dough, shape into a loaf, and place in a greased loaf pan. Cover and let rise for 30 minutes.

6. Preheat the oven to 350°F (180°C). Bake for 25–30 minutes until golden and the loaf sounds hollow when tapped.

7. Remove from the pan and cool on a wire rack before slicing.
