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 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."

"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."
