Minor success! Compared with a tim tam, a kit kat makes for a poor straw. I think the wafers are more densely packed in the kit kat, requiring more effort to draw in liquid.
That said, I was able to produce the pleasing texture of the molten tim tam almost exactly, and the combined tastes of coffee and kit kat were pleasing.
I give the kit kat 3 out of a possible 5 tim tams.
