Mix maida, yeast, salt and onion seeds in a bowl. Add 2 eggs, oil and warm milk to the dry mix. Bring it all together. Knead well for about 5 minutes adding flour and oil if needed. Apply some oil on the dough, cover and let it ferment for 2 hours.

Divide the dough into 4 equal parts. Grease a microwave safe flat dish with oil and place a dough ball on it. Flatten the dough with hands turning the dish as you do. Flatten from the centre while keeping the outer ends thick. Mix egg yolk and milk and brush all over the naan. Sprinkle black and white sesame seeds all around the centre and the edges Prick a few holes in the centre section. Prepare other naans similarly.

Preheat the oven at 180°C. Bake the naans for 30 to 35 minutes. Enjoy!
