From the three ingredients (1kg of mixed dried fruit, 600ml,choccolate milk, 2 cups self-raising flour) it sounds to me as though it is going to turn out pretty stodgy and/or gludgy, and not rise much. The high proportion of fruit will make it taste sweet, but it will be pretty heavy. Rather like the Allbran "regularity" cake.
What is wrong with "normal" recipes with only one or two other ingredients? For instance, the "boiled fruitcake" I have made successfully for the last 60 years? Mixed fruit, SR flour, margarine, eggs, sugar - only five ingredients (plus water) and no more work.
I'll be interested to hear the verdict after posters have tried it.
