Gimme a break of that Kit Kat bar

Of candy bars, Kit Kat is my favorite, a combination of wafer covered in a thin layer of chocolate. Kit Kat bars are so dangerous that I refuse to go down the candy/snack aisle in Costco for the fear that I will purchase one of their bulk boxes of Kit Kat (which would be devoured quite quickly).
A Kit Kat of this size would be death to me. It's a good thing that all the ingredients used in the construction of this enormously super-sized candy bar are British, else I would be tempted to try this at home. Britons have a larger variety of KitKat bars than we have in the States -- the gigantic bar pictured here is the chunky peanut butter variant of the KitKat family. I've heard that there's Dark Chocolate and Mint varieties of Kit Kat as well.
One of these days, I will try this recipe with US ingredients, and then I will explode from my gluttony. But at least I'll be happy.
