Soak 1 cup of cut up dates and a tablespoon of bicarbonate of soda in 3/4 cup of boiling water. In a separate bowl mix 125g soft butter, 125g sugar and one egg. Then add 250g flour, vanilla essence and 1/2 cup roughly chopped walnuts.
When I cut it open I was really worried because it looked worryingly dry. To my surprise it was lovely and moist. A real treat!
