Ingredients
170g/6oz SR flour
115g/4oz coconut
75g/3oz sugar
3 heaped tsp cocoa
pinch of salt
150g/5oz butter or marg
100g/3.5oz galaxy (or other suitable) chocolate
Method
Sieve flour, salt and cocoa into a mixing bowl. Rub in the butter/marg to breadcrumbs stage. Stir in sugar. Stir in coconut and sugar and knead well. Line swiss roll tin with parchment paper and press mix into it. Bake at 140*C for 25 to 30 minutes and cool in tin. Top with melted chocolate and when set cut into squares.
I used fruit sugar in place of sugar and reduced the amount to half. I also accidentally used tablespoons of cocoa instead of teaspoons, but I can assure you the taste did not suffer.
