While this is a wonderfully delicious cake, there are some problems. First, at nearly 300 calories a slice, it's not exactly a dieter's dream. I guess it's low in fat, but calories ARE fat if you don't burn them, so be aware. Second, it took me most of an afternoon to make it. The commercial fruit puree mentioned doesn't seem to be sold in stores anymore, so I had to make my own. I cooked up and processed some prunes, which wasn't hard, but the procedure did add about 30 minutes to the project. I made this for my husband's birthday and would probably only make it for special occasions. We sliced it a little thinner than the recommended serving size, so it was a little lower in calories. It is an awesome cake, but when you consider that you can make a Betty Crocker Dark Chocolate cake from a mix that's only about 280 calories per serving (unfrosted, of course), you have to wonder if this one is worth the time.
