I love butterscotch, it appeals to my sweet tooth and my general gluttonous side. Wikipedia says that the origin of butterscotch is a bit of an unknown, read about it http://en.wikipedia.org/wiki/Butterscotch.
So in my 1001 Recipe Cook Book: Recipes For All Occasions, I found Butterscotch Walnut Brownies. This doesn't appear to be a 'typical' 1970s recipe and if I was asked to write what dishes personified the 1970s I wouldn't necessarily say that this was really one of them. However this includes two of my favourite ingredients so I can't really keep it to myself.
125g/4oz brown sugar
2 eggs, beaten
5ml/1 teaspoon of vanilla essence
75g/3oz self-raising flour, sifted.
50g/2oz chopped walnuts
1. Cream the butter and sugar together until fluffy.
2. Beat in the eggs then the vanilla essence.
3. Fold in the flour, then the walnuts and mix well.
4. Spoon the batter into a well-greased 18cm/7 inch square baking tin and put into a preheated oven at 170 Celsius/325 F and bake for 35 to 40 minutes or until firm. Cut in to squares and serve.
