This is super yummy! But don't do what I did; use real butter in the frosting! I used margarine and it was meh, but butter would have rocked it hardcore (wished I had used butter) otherwise made exactly as stated. The bars were so moist and delicious, 5 star good!

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:)

I am the submitter of this recipe. I think the personal recipe version has better instructions. Here's a link to it: BTW, his recipe is great without the frosting.

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.

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.

I brought it to work and my office girls loved it.. Some asked for the recipe. And many people loved the frosting. I halved the frosting and I baked it in a cake pan.Frosting was a perfect amount for me. and next time I make it I will omit the frosting. I think it would be great without it

Allie has a winner with this recipe! I made this for our November Girls Night Out group, and they loved them! The personal recipe calls for this to be baked in a 13x9 pan, and the published recipe calls for a 15x10 jelly roll pan. I used the jelly roll pan, but it was an inch or two, too short. My cake started going over the side of the pan and a small portion went on the oven floor - ugh. The bake time of 27 minutes was perfect in my oven. The end results were a nice, moist, dessert that cut very nicely. The brown butter frosting is delicious. It is the first time I've made frosting like this. Loved it....and I will be making this dessert again. Thanks Allie for sharing your recipe.
