Hubs never came across a banana bar he didn't like, including this one. This is a classic banana bar recipe, but its distinction is with the browned butter frosting which I thought was a nice complement. Great taste, lovely frosting, but I prefer mixing up the batter using the traditional creaming method - cream the sugar and butter well, add the eggs and vanilla, and finally the bananas. Add the flour mixture alternately in thirds with the sour cream beginning and ending with the flour. A second helping for Hubs after supper? I'd call these a hit! Read More

The bread portion of this recipe turned out great but once I added the frosting it was WAY over powering and I could not taste any banana. I had to scrape all the frosting off so I could eat it. If you like an incredibly rich and heavy butter cream try the recipe but even then I d recommend halfing the frosting and altering it to more of a glaze or do a lighter cream cheese frosting.

I am the submitter of this recipe. I think the personal recipe version has better instructions. Here's a link to it: http://allrecipes.com/personalrecipe/63791412/banana-bread-bars-with-brown-butter-frosting/detail.aspx BTW, his recipe is great without the frosting. Read More

These deserve more than five stars. I cut the recipe in half and baked them in an 11x7 glass baking dish for the same time given. Otherwise, I made no changes. I like that these are actually "bars" that you can cut and eat out of hand, unlike other "banana bar" recipes here that are more like cake and require a fork and plate. The frosting is incredible...don't leave it out!! I cooked the butter for exactly 3 minutes on medium heat and it was perfectly browned. Our new official banana dessert here. Thank you:) Read More

I used an 18 x 13 jelly roll pan and had no problems with batter spilling over the sides. I reduced the bake time to accommodate the pan size. My bananas were completely black which gave theses bars a very good banana flavor with just the right sweetness. We like nuts so I doubled the amount called for in the batter and also chopped some to top the frosting. These bars are very moist and delicious. I will definitely make these again. Thanks Allie.

I have made this recipe twice with rave reviews! Of course anything with browned butter frosting on it is ok in my book.:-) I used black walnuts from the tree in our yard (so yummy) and parchment paper in the pan to easily lift bars out to cool before icing. Read More

I helped my kids make these for their Super Bowl party. While they were moist and delicious I thought they were a little too sweet once the frosting was added. Next time I would use a smaller pan so the bars would be thicker and then halve the frosting. They'd be good with just a dusting of powdered sugar too. Read More

These bars are really really good. I followed the recipe with the exception of using a 8x11 glass dish. They took about 45 minutes to cook. They are so moist and full of flavour and I know that I will be making these again and again. Thanks AllieGeekPi for this wonderful recipe. Read More

These bars were absolutely moist and delicious. I didn't make the frosting because they were so scrumptious on their own. If their was a rating for 10 stars this would definitely rate as such. Read More

Halved recipe and baked in 7" x 11" as another reviewer suggested. Turned out perfect these are not too rich and I like that the frosting makes just the right amount - not too much. Read More
