These bars stay very moist, and their rich banana and chocolate flavor is even better the second day. My mother-in-law gave me this recipe, and it's a big favorite with both my husband and two sons.—Rene Wright, Ferryville, Wisconsin

"I was looking for a new way to use "old bananas" and this is NOT it. These are boring and non-exceptional to say the least. They DO stay moist, I will give them that, but I would guess that a variety of additions as suggested by other readers are a definite need."

"I too have been making these bars for years. A great recipe to use up bananas. I did change the recipe a little. I eliminated the cocoa and added a half cup of mini semi chocolate chips. To divide the batter was time consuming for me."

"This is an awesome cake, been baking it for over 15 years and it's a family favorite. I brought it in to work today and everyone is going crazy over it, lol. It's a winner even after all these years!"

"It's didn't seem enough batter for a 13x9 pan so I used a 9x9 pan. I added 1/2 c chocolate chips to the top and 3 minutes more to the baking time. Delicious! Yes, more cake texture than brownie."

"Easy and really yummy. I did add some chocolate chips - spread them between the 2 layers. A keeper."

"Good but not great. Added the mayo and chocolate chips as other reviews recommended. Not very chocolately. A nice change but I'll be going back to my "old faithful" recipe next time."
