    YUM, YUM, YUM! This recipe couldn't have come at a better time--my bananas were BEGGING me to use them for something. I have tried some of the other popular banana bread recipes on this site, but always went back to my wonderful old standby. I decided to give this one a try, and I am SO GLAD I did! It came out of the oven smelling heavenly, and I cut a slice right away (burned my mouth eating it too!). THIS IS EXCELLENT! I did make a couple of changes--I used 1/3 cup canola oil for the shortening (healthier), and I used all brown sugar, because I like when the cake looks darker. Those changes worked out just fine! I think the oat flour adds an interesting flavor. Thanks sooooo much, Verona!  -  18 Jul 2003  (Review from Allrecipes US | Canada)


    This cake had a great banana flavor. It was moist and dense, for the most part. I found that the 8x8 square pan was too small. It made for a very deep cake that didn't cook in the middle. I left it in the oven for 15 extra minutes and the edges were getting a little too dark by the time the center was cooked enough. Since the directions mentioned vanilla even though the ingredient list did not, I added 1 tsp. I also used butter instead of shortning - just a personal preference. My biggest quibble was with the topping - way too much and way too dry. I'd cut everything to 1/3 but the butter. With those adjustments, I would definitely make this again.  -  30 Jul 2003  (Review from Allrecipes US | Canada)


    Great crunchy outside/moist inside banana cake! I made some slight changes to the original recipe: I add an additional half cup of mashed banana and prepared the topping with oat flour instead of rolled oats (that I happened not to have) and the result was just perfect. Plus add cinnamon to the topping (1 full soup spoon)  -  09 Mar 2006  (Review from Allrecipes US | Canada)
