BANANA BREAD BARS
Bananas are a hot commodity in my house. My husband snags them when they’re still green and freezes them for his protein shakes.
Something I don’t really understand but I’m sure he’s explained to me the scientific reason why underipe bananas are better for his workout shakes.
Then there’s my little baby Wes who eats one for breakfast every morning.
This week Wes boycotted bananas and the bananas sitting on my counter were too ripe for John’s muscles so I found myself looking at a bunch of overipe bananas getting more ripe by the minute.
My usual go-to is my favorite Banana Bread. Ohhh, it’s good. But today I made these Monkey Squares.
It’s super moist sour cream banana squares topped with a browned butter frosting. I found the recipe from a comment from a reader on another blog.
I love finding recipes in obscure places. It’s a family favorite recipe…my favorite kind of recipe.
This picture does not do these Banana Bread Bars justice. I LOVED them. They are good warm, cold, and room temperature. Browned butter anything gets me every time. Make these…
WHAT IS BROWNED BUTTER?
Browning butter adds a whole level of flavor to anything. You cook butter over medium low heat until it starts to turn brown and has a nutty flavor.
To prevent the butter from overbrowning it’s wise to transfer the browned butter to another bowl when it’s done instead of letting it sit in a hot pan which can cause it to cook longer.

Monkey Squares
These Monkey Squares are soft and moist banana bread bars with browned butter icing. Think of the best banana bread made into easy to eat bars.
Ingredients
- 1 ½ cups sugar
- 1 cup sour cream
- ½ cup unsalted butter, softened
- 2 eggs
- 1 ¾ cups 3 or 4 ripe bananas, mashed
- 2 teaspoons vanilla
- 2 cups flour
- 1 teaspoon baking soda
- ¾ teaspoon salt
- ½ cup chopped walnuts (optional)
- ½ cup unsalted butter
- 3 3/4 cups powdered sugar
- 1 ½ teaspoons vanilla
- about 3 tablespoons milk or half and half
Instructions
-
Heat oven to 375 degrees. Grease and flour 10x15 jelly roll pan or line with parchment paper (for thicker bars use a 9x13 pan and bake for 10 minutes longer than directed). Beat first four ingredients until creamy. Blend in bananas and vanilla for one minute. Add dry ingredients and blend for one minute. Stir in nuts and spread in pan. Bake 20 to 25 minutes until golden brown. Cool slighty until warm but not hot and frost with Browned Butter Frosting (recipe below).
-
For the Browned Butter Frosting: Heat butter in saucepan over medium heat past the melting point until it is boiling and a delicate brown. Remove from the heat and immediately add the remaining ingredients. This should be thicker than a glaze and thinner than frosting. You can add milk to get it to the correct consistency. Using a spatula smooth over the top of the Monkey Squares immediately. The frosting will be easier to spread once it's on the warm bread.

Super easy too 💋
Thanks!
Great recipe! I used Crème fraîche in place of the sour cream- super moist and delicious… This recipe is a keeper…Thankyou.
It’s one of my favorites too.
Thanks for the recipe! My kids love it and it’s delicious!
You’re welcome!
It’s my second time making these there a big hit 🍌🐵
Awesome!!!
Never mind, I just saw someone already asked 😊
Do these need to be refrigerated?
Amazing! So much so that I baked 2 the second time.
I’m looking to recreate this frosting in a cupcake workable version. Any recipes? Any ideas?
Ooh to be honest. I haven’t tried it, but I like the idea.
Do these have to be refrigerated or can they be left out?
I leave them out.
Delicious! Thank you for our new favorite for bananas past their prime. My mods were to add peanut butter chips to the batter and Kahlua to the frosting to help cut the sweetness.
Wow. Bet that was good.
Loved this!! I did not have sour cream or plain yogurt so I used my sigg’s coconut yogurt. So moist and delicious…will definitely make again!
I bet the coconut was so good.
OH MY GOODNESS. Just made these and they are sooooo good. Thank you for sharing this recipe!
Thank you!
So delicious! Thank you! I like putting on the icing when the cake is still hot. It melts right in and turns everything into a golden caramel-banana deliciousness! So good!
Thank you!
We’ve made these before but decided to add mini chocolate chips this time. So delicious!
Just made these and my family loved them! I just wondered if these could be stored at room temperature or if they need to be refrigerated. Believe it or not I have some left…
I don’t ever refrigerate them but if you leave them out longer then a couple of days you probably should.
Just made these. I subbed applesauce in the bar part and used a 9×13 pan. Oh my they are good.
Thank yoU! I agree.
I made these Monkey Squares and it was the most amazing banana cake I have ever tasted. I took them to work, because I work with all men and they love it when I bring a new recipe in. Everyone LOVED them. They also asked “What kind of frosting is that?” It is is a little better than just a vanilla frosting. Anyway, you will not be disappointed. I will definitely be making this again!
Thank you! I love hearing that DEb.
I love this treat! I prefer the original name I found it under, though : Monkey Bars. Totally cute. I’ve made these to feed a cast and crew on my hubby’s movie …. and I’ve made them as just a family treat, and I’ve mad these as a birthday cake 3 times now. It’s always a huge hit! So delicious! Thanks for the fun and yummy recipe Christy!
You’re welcome! Greta how are you? Your hubby’s movie? I want to know more.
So it was my first time making these last night and everything was going soooo smoothly until….I poured the frosting on top of the already baked banana bread. It spilled over the pan and all over the stove where I had placed the pan to cool down. I was frozen for a couple of seconds trying to figure out how I had not thought about this before. Like Hello!!!! I kept thinking I should have read the comments before to see if there were any tips but then again I may have been the only one that this happened to. The frosting did not come out as thick as maybe it should have but as it cooled it definitely got thicker. It’s def more like a donut glaze, still delicious. This was a hit at home and at work. Next time though I might just try putting the powder sugar over the cake after it cools down of course. ;D
Oh no. Did you use a jelly roll or 9×13 pan? I’ve never had this happen to me.
OMG these were amaze balls. I cant wait till my fiance gets home for work so he can try it.
I love that you said amaze balls. I say that all the time.
Simply fabulous! I always put overripe bananas in the freezer so they are handy with just a quick defrost. Had a few such frozen assets available so I made these last night and brought them in to work today. I baked them in a 13×9; they took 35 minutes in my oven. I misread the amount of salt in the batter but couldn’t tell the difference. I will definitely add these to my baking rotation. Thanks for sharing!
You’re so welcome! I love them.
I just made these and they are absolutely to die for! After reading the comments about the browned butter icing being too sweet I decided on a brown sugar glaze. PHENOMENAL!! Thanks so much for sharing your recipe.
You’re welcome!
The cake part was good but the frosting was so sweet. I’m thinking there is a typo with 3 and 3/4 cup sugar. Everyone thought it was nice but too sweet.
It is a sweet frosting. It’s not a typo though. it’s 3 and 3/4 cup.
I have made these over and over again for so many family functions because they are always a huge hit! Thank you for such a fabulous recipe!
You’re welcome! So glad you love them too.
Hi could use frozen banana ..looking yummy
Hmmm. It might make them too wet? I haven’t tried it so I can’t be sure.
I’ve made this recipe several times now and we LOVE them! I told my son this morning that I was going to be making these for teacher appreciation (thanks a bunch), and he said, “Yes! I love those so much! I can’t wait!” Thanks for yet another fantastic recipe!
I’m so happy to hear that!
How many servings are in this recipe?
About 18. Depends how small you cut them.
This is so much better than banana bread. I think my frosting was a little on the firm side because it was too sweet for my taste. It was tasty though. It taste like toffee.
Haha – okay! Glad you liked it.
I made these following the recipe minus the nuts. They are very yummy, but very, very sweet.
Just made these didn’t have sour cream so I blended some cottage cheese with some lemon juice. Turned out great very moist!
Glad that worked out!
These look wonderful, I can’t wait to make them for my girls night this Saturday! Do they need to be refrigerated? And how long would you suggest baking in a 13×9 pan?
They definitely need about 10 minutes more than the suggested baking time.
I’ve made these twice, both in a 9×13″ cake pan. They’re seriously amazing. I could eat the entire pan if I didn’t mind getting sick. 🙂 The frosting seemed a bit too sugary for me, so for the first batch I cut the powdered sugar in half (used the amount of butter, milk, and vanilla the recipe originally called for), and the second batch I used a tad more than 1.5 cups of powdered sugar. Both were awesome. Thank you so much for sharing this recipe!
You’re welcome!
