I adapted this recipe from Mary Ford's Biscuit Recipes book
3 oz Butter
6 oz Caster Sugar
1 lge Egg
3.5 fl 0z Milk
6 oz Self-raising flour
3 0z light brown soft sugar
1 oz Self Raising Flour
1 oz Butter
2 oz Chopped Nuts (I like Pecans but she say's Walnuts)
For the cake bit : beat together the Butter, Sugar, egg, milk and flour in one bowl
For the filling : mix ingredients in a bowl to form a crumbly mix
To bake : put half the cake mix in a cake tray 8 in square, sprinkle half the filling on top, then put the rest of the cake mix on top and finish with the remaining filling.
Note : I have made this a couple of times and struggle with these instructions so you can do what I do and that is to put all the filling mix in between the two cake layers and bake as is and then make a very thin drizzle icing to put over the cake when cold.
Bake in a pre-heated oven 170oC - gas mark 3 for 35-40 mins
Leave in tin until cold and cut into squares when cold
