I usually buy a double decker on a friday as a treat for my lunch. The rest of the office splashes out on bacon sandwiches. The little buggers always take some finding though. The corner shop always seems to move the position of them every week.
My parents sometimes buy Double Deckers, probably when they're 2 for 1 at Tesco or something. But there was a big gap between whenever I last had a Double Decker as a kid and whenever I started eating them again in my late teens. I'm sure they've completely changed, like many things. The chewy bit at the top is delightful, like a pre-melted marshmallow, or a chewier nougat. But the bit of the bottom is almost inedble. Trying to bite it is like trying to bite a rock. Like Fuses, remember them?
I never knew peanut Kit Kat Chunkies existed -- I must look out for them. I love anything to do with peanuts. Peanut Lions are probably my favourite chocolate bar ever.
Never liked creme eggs, they are far too sickly for me.
