Nestlé Rowntree has taken a lot of flak in recent years for the many extensions it has made to its Kit Kat brand, but it isn't going to get any from me for its delicious Chunky Peanut Butter variant. For too long now it has been the Americans who have had all the peanut butter options, while us Brits just had variations on traditional caramel fillings, so hats off to Nestlé for bringing a taste of the States across the Atlantic. I reckon this flavour is definitely here to stay. I hope so, anyway.
