Why does my mars bar slice go rock hard?!

[bigglet]

I've tried making this yummy slice several times and every time it goes so rock hard that you break teeth trying to eat it!

What am I doing wrong?! Help!!

Can I see your recipe?

Do you think having the mars bars melting for too long has anything to do with it? Maybe too much boiling of it?

Don't let it boil. Just let the butter and mars bars melt and mix together until it looks sort of stringy. The caramel is getting to hot and setting hard if you let it boil.
