If you like Snickers bars, and you like flapjacks, though: you might like these:
Snickers flapjacks
200g rolled oats
55g plain flour
120g butter
2 1/2 tbsp golden syrup
90g caster sugar/whatever sugar. Muscavodo's nice if you can find it.
2 standard size snickers bars
Heat oven to gas 4/180C. Grease a square tin, unless you have a handy rubber one like I do, which I strongly recommend, as it needs no greasing and brings it out clean.
Heat two pans: one with water to boil in, one without. Begin to melt the snickers in a bowl over the boiling water. Meanwhile, melt the butter, sugar and syrup on a low heat in the other pan; stir both continously.
Mix the flour and oats in a bowl, then add the sugar/syrup liquid, then the melted snicker bits.
Spoon the mixture into the square tin and flatten with its back. It'll need up to half an hour in the oven: check that the top is golden, and remember that it'll harden when it cools so needn't be too solid.
Definitely best eaten whilst still warm. It might not be to everyone's taste, but you create do this with any chocolate bar you fancy, Sometimes the most unrelated combinations can be the most effective.
