No I haven't tried it, a part of me wants to try to make it but another part says it's not quite as simple as it looks. Microwaves are difficult to get something to a consistent, specific temperature, so I'd either over or under do and make a big mess.
It sounds simple enough but now I'm reminded of a conversation I had with my Argentine Spanish tutor, she too found a microwave recipe for a cake and it ended up exploding in the microwave during the process and making a big mess. So go at your own peril lol.
