Making ice cream

I bought this packet of Chocolate yogurt ice cream some time ago and it is going to expire soon in Jun. So today was the day. I have tried making it before and I recall it was quite easy. I just had to mix the powder with water,
freeze it for about an hour and try to beat it to twice its volume. The last part was tough as no matter how I beat it, the volume still looked the same to me (and I was too lazy to activate the electric mixer since I used it earlier to prepare the cheesecake batter and I didn't feel like washing the mixer a second time) . So I just leave it to continue to freeze in the freezer. Currently it looks like this:

Hopefully tomorrow it will be creamier :)
