At first I was going to bake something more 'complex' ('complex', in my term means mixing and measuring the raw materials from start to finish, not using the premix packets). However due to the time constraints (we will be going to overseas soon, we aimed not to cook anything exciting this week so we can keep our fridge as empty as possible) I can only make something small, simple and quick.
Anyway, I spotted this packet in the supermarket, you only needed to put milk into this premix powder and then it's ready to go in the oven.
