It really is that simple. In fact, I only added measurements to make it easier to follow. I don’t tend to measure things out and so if I’d wrote this recipe in the manner of how I make things it would read: a glug of milk, with a splash of vanilla extract and a sprinkling of cinnamon. That’s the beauty of cooking though, you can just go for it and trust your judgement and if you are a little bit over or under, so be it.
Have fun with this recipe and hope you like it (or your mum does!).
