Add the warm milk, sugar and yeast in a bowl. Leave until bubbles come out.

Then after bubbles come out, add in the egg, combine well.

Add in the flour and salt. Combined well with a spatula, then add in the butter. Combine again.

After it combines well, leave in a warm spot for 90 minutes until it doubles in size. Don't forget to cover it with a plastic wrap.

After that divide the dough. As many as you want, shape it any shape you want. I just make some balls then add in the cheese and then put them in muffin tins.

Then leave them for 30 minutes to rise, cover with some damp kitchen towel. Brush with some whisked egg yolk.

Bake in preheated oven for 20 minutes at 180°c (time may vary to oven).
