No, not the Android OS version but the actual candy bar.
Bought this at a Japanese grocery store in Vancouver:
The instructions say to toast the bars until browned, like the picture on the front of the package. And for better results, refrigerate them before toasting. I didn’t refrigerate them.
They tasted pretty good! Quite a novel way of eating KitKat bars. I wonder if the same can be done with regular flavour KitKats.
