    Absolutely delicious. The only thing I changed was instead of chopped walnuts I added 1/2 cup of sultanas.  -  22 Dec 2016


    I've gone through a kazillion banana recipes (16 from allrecipes alone) and these were fine, but I recommend others more. Especially since shortening is very unhealthy - if these tasted great, I wouldn't care, but I try to make sure the taste is worth the health effects! Used 1/3 cup b.s. and 2/3 white; 2 bananas; did not make frosting, just sprinkled hot chocolate mix over top, which was good. If you want thick bars, use a 9x9 pan - this goes fairly thin in a 9x13. But, I suggest you make Mocha Chocolate Chip Banana Muffins, Banana Cake VI (a real winner), or Banana Chocolate Chip Cookies from this site instead.  -  14 Aug 2006  (Review from Allrecipes USA and Canada)


    Good basic idea for a recipe. Having to change it this much means it is basically a different recipe entirely which is why I gave this particular version 2 stars, the new and improved version would definitely be a 5. I used 3 small bananas in the bars, I added an egg, I cut back to sugar to 2/3 of a cup, no salt, no lemon juice, no walnuts although they would be nice, my preference is pecans which would also be good. They baked at 350 for 20 minutes. The frosting IMO is too much, just too sweet and not really necessary with the great banana taste of the bars themselves. So I frosted first, then scraped most of it off, leaving a very thin almost glaze like covering, which is how they will be made next time.  -  17 Jan 2006  (Review from Allrecipes USA and Canada)
