In the large bowl mix all dry ingredients and combine well.
In the smaller bowl whisk soft butter with eggs yolks and pour the liquid into the dry ingredients and combine for another minute. If you use a stand mixer you don't have to mix the eggs separately. Let's combine for 7 minutes or until the dough is flexible and soft.
Once the dough is mixed well, you can also knead with your hands to make sure the structure of the dough is done properly. Add raisins or chocolate chips and combine.
Brush a large bowl with vegetable oil and place the dough into the bowl and cover it with plastic wrap or towel. Let it rise for another hour or until the dough gets double size.
Once the dough rises make the same size loaves or plaited the bread. You can play with the shape of the bread.
Let it rise for another 40 minutes.
Slightly brush over with the egg and put it into the oven for 40 minutes or until the bread is golden and properly baked inside.
Let cool it down or enjoy warmer with butter.
