If you go onto the Nestles Condensed Milk website, you can get an idea. I use their recipe for Banofee pie and this entails boiling Condensed Milk with Brown Sugar and Butter. But did you know you can buy tins of Caramel by Nestles? They are on the shelf in the Supermarkets where the Nestles Condensed Milk is. This would be perfect for a toffee sauce as the toffee I use in the Banofee pie is delicious.
You could make a toffee sauce by mixing cream and brown sugar in a pan gently bringing it up the boil,if you want a caramel you can boil up a can of condensed milk for a couple of hours making sure that you never let the pan dry out
Thankyou all but I have just realised I made a mistake it should have read " Sponges with caramel/toffee soft in the middle when cooked". I have made the chocolate one but would prefer the caramel flavour.many thanks
