Are you the type of person who has the ideal point of ripeness for your banana, but won’t eat it even if it’s just one minute past its prime? Unless you buy only one perfect banana at a time, that probably means you have a never-ending supply of overripe fruit sliding into the darkness and nowhere to go with it all.

Don’t throw them out. Homemade banana bars to the rescue!

As soon as your bananas hit the point of no return, just peel them, bag them up, and stow them in the freezer. Add those overripe bananas to a smoothie, homemade pancake batter, or this amazing dessert.

No matter what your number on the ripeness scale, you’ll probably go B.A.N.A.N.A.S for this dessert. It’s light, fantastically banana-flavored, and ridiculously easy to bake. And the Cream Cheese Frosting adds even more next-level deliciousness. Fair warning, though: it’s impossible not to sneak sliver after sliver as you walk through the kitchen.

As it’s written, this recipe uses up three whole bananas in your stash. And hopefully, by the time you finish the cake, you’ll have three more ripe bananas ready to go. But that’s okay. Like all good bar recipes, this dessert is made for sharing, so don’t be stingy—spread the love!

Making Banana Bars for all your co-workers? Smart. Just click and slide the number next to “servings” on the recipe card below to adjust the ingredients to match how many you’re feeding—the recipe does the math for you, it’s that easy.

Banana Bars vs. Banana Cake vs. Banana Bread:

With three eggs, this recipe definitely has more of a softer cake texture than the bars you may be used to. It’s old-fashioned and, in my humble opinion, handles the frosting perfectly.

What it’s not is a firm, chewy, crumbly sort of bar. Nor is it a dense and solid like banana bread.

Making different sizes/styles of banana bars:

To maximize the number of bars in this recipe, the batter is spread out in a large 15-inch by 10-inch jelly roll pan.

If you don’t have a large jelly roll pan, you can use two 8-inch by 8-inch pans baked in the oven side-by-side.

That said, if you want to turn this recipe into cupcakes, or you prefer a thicker sheet cake, you can do that, too.

For banana sheet cake, pour the batter into a prepared 13-inch by 9-inch pan. Then bake a little longer (35 minutes or more) until a toothpick inserted into the center comes clean.

For cupcakes, line a 12-cup muffin pan with cupcake liners, then line a second pan with 6 liners as this recipe may yield up to 18 cupcakes. Pour/spoon the batter into the liners, until about 2/3 full, avoiding spilling over the sides. Bake for 18 to 20 minutes, or until a toothpick inserted in the center comes out clean.

What you need to make Banana Bars:

  • Flour.
  • Baking soda. Helps the bars rise.
  • Salt.
  • Butter. Softened, please.
  • Sugar.
  • Eggs.
  • Mashed ripe bananas. (Three, to be precise.) If frozen, let them thaw on the counter while you get things ready. If you need a fast hack for ripening bananas STAT, see the tip below.
  • Vanilla extract.Banana bar ingredients in various bowls.

     

Optional ingredients:

  • Cinnamon. Or any warming spice (like nutmeg, ginger) might be nice.
  • Raisins.
  • Chopped walnuts or pecans. A couple handfuls of chopped toasted nuts adds lots of texture to the bars. You could also sprinkle the nuts over the frosting layer, if you choose.
  • Chopped candied ginger.
  • Mini chocolate chips. Chocolate chip banana bars, anyone? I thought so.

What you need for Cream Cheese Frosting:

  • Cream cheese. One package per recipe.
  • Butter. Softened, please. One stick per recipe.
  • Powdered sugar.
  • Vanilla extract.

How to make the best Banana Bars:

This recipe walks you through the steps, but if you need exact ingredient amounts, take a look at the recipe card below; it has all the deets.

  1. Turn the oven on to 350 degrees, then bust out your stand or handheld mixer and a paddle attachment. Next, coat the inside of the baking pan with non-stick cooking spray or a thin layer of butter.
  2. Then whisk together the dry ingredients: flour, salt, baking soda in a medium bowl. (If you’re using cinnamon or another spice, add it here.)
  3. Next, beat the softened butter and the sugar together using the paddle attachment. Continue until the mixture turns pale and fluffy.
  4. Then mix in the mashed ripe banana and the vanilla, beating until well incorporated.
  5. Next, add the eggs one at a time, beating well in-between each one.
  6. Gradually add the flour/dry ingredients and mix just until the batter is uniformly combined. (Any nuts, candied ginger, chocolate chips go in at this step.

  7. Then pour the batter into the prepared pan and bake for 20 to 25 minutes. When finished baking, a toothpick inserted into the middle of the batter should come out cleanly, with only a few crumbs on the toothpick.

Then, patience. Before you frost the bars, they must be absolutely cool to the touch.

How to make the cream cheese frosting:

Sweet, rich, and indulgent, this homemade vanilla frosting tastes incredible on almost anything—but especially banana bars.

  1. Wash out the mixer bowl and rinse off the paddle attachment. You’ll need it again to make the frosting.
  2. With the mixer, beat the cream cheese and softened butter until smooth. Then add the powdered sugar in small amounts (a sifter or mesh sieve works well for this) and the vanilla, and continue to beat.

Frosting the bars:

After you’ve channeled the patience of a saint and the freshly-baked banana bars are completely, 100% cool, you’re ready to slather on the frosting.

Spread a thick layer over the uncut bars. That’s it!

Making healthy banana bars:

  • Lower the sugar. Cut the sugar in the recipe in half and add 1/8 cup of honey. Or, substitute a sugar-free baking product for the granulated sugar in the recipe.
  • Make gluten-free banana bars. Switch out the all-purpose flour for your favorite GF baking flour blend.
  • Use banana flour. Green banana flour is a gluten-free option that has banana flavor, too! It may result in a denser end product, though, so use 3/4 cup banana flour for every cup of flour in the recipe.
  • Raise the fiber. Substitute 1 cup of whole wheat flour and add 1/2 cup of flaxseed meal to the recipe for added nutrition, heart healthy benefits, and dietary fiber.
  • Add more bananas. Adding one or two extra bananas ups the flavor, but may effect the overall consistency of the bars. You might have to bake the bars a little longer, too.

Can’t wait? Here’s how to ripen bananas quickly:

  1. Preheat the oven to 300 degrees. Then line a baking sheet with foil.

  2. Arrange the number of unpeeled bananas you need on the prepared baking sheet. Bake until banana skins are completely black all over, about 15 to 20 minutes.

  3. Cool. Scoop the banana pulp from the peel, then mash.

Toting, storing, and freezing Banana Bars:

To bring frosted banana bars to a party, keep them in the pan. Stick toothpicks at regular intervals into the frosting, then drape plastic wrap lightly over the toothpicks. This looks funky while you’re on the road, but it prevents the plastic from sticking to the frosting.

When you’ve arrived at the office/party/shower, you can remove the wrap, then the toothpicks and serve ‘em up!

Will you be storing leftover banana bars? Well, this is going to have to be heavily researched, because around here, banana bars just don’t last that long—they’re always eaten.

If you’re going to eat the bars in the next day or two and your house hovers around 70 degrees or cooler, the bars should be fine to sit on the counter, even with cream cheese frosting.

To freeze banana bars, tightly cover unfrosted or frosted bars and freeze them up to 2 months. When ready to eat, let them thaw in the refrigerator overnight.

    This looks delicious! Should salted or unsalted butter be used? Thank you – can’t wait to try it.

    1. meggan

      Hi Irene! Technically you should probably use unsalted butter for everything because salt content varies by brand of butter. However, my mom (and all my friends and relatives in Wisconsin) don’t buy unsalted butter, ever. I’ve made it with both, it’s delicious with both. I honestly can’t tell the difference. There is a pinch of salt in the recipe, but it’s not going to taste salty if you use salted butter. I hope that helps! It’s a great question. Thank you. :)

  2. Ha! I LOVE that you can (probably) eat more than me, Meggan. Next time I out-eat everyone at the table, I’ll think of you!!
    The banana cake it stunning. Stunningly simple, too. I have a bit of a battle on my hands to get to the browning bananas before my husband throws them away (!!) but this is a great idea if ever i do have some bananas needing immediate usage!5 stars

    1. Sarah

      Bake bananas in the oven at 350 for 40 minutes! Line the pan you bake them in in case they leak!

  3. Banana bread AND Mitch Hedberg quote? Great blog! and photography :)

    1. meggan

      Ha ha ha! Thanks. :) Yeah that Mitch Hedberg quote is one of my favorites and I’ve just been WAITING to pull it out. Photography – thank you! I try very hard, the struggle is real, it doesn’t come naturally, all of that. It’s a lot of practice, I take several hundred photos per week and eventually I get better, very slowly! Always room for improvement! Thanks again. :)

  4. 1. I love banana bread! 2. I could eat cream cheese frosting out of the bowl. 3. I’ve never had the two together, but it sounds like the perfect pairing! 5 stars

  5. Agreed! I wouldn’t share either ;) 5 stars

  6. Valerie Klobuchar

    Can this be made ain a 9×13 pan?

    1. meggan

      Hi Valerie, I made this cake in a 9″ x 13″ pan today. It worked out great! I ended up baking it 50 minutes total at 350 degrees. The thing you have to watch for is making sure the center is set. I know that probably sounds obvious, but there were multiple times where I thought the cake was done but the center wasn’t. The top gets browned, but it tastes perfect. I actually left the frosting off today too, and it’s like a giant pan of really great banana bread! I’ll update the recipe to reflect this info. Thanks for the question!

    2. meggan

      Hi Valerie, yes. I have made it that way. But, I think I had to bake it longer, and I do not recall exactly what that bake time was. I will test it again though and post my results. You won’t have the 50/50 cake/frosting ratio though… for better or for worse! ;)

  7. Jeff

    What a great idea! Mine usually wait out until I get the urge to make banana bread, but this looks even better! Great recipe.

  8. Great use for bananas….plus it’s frosted….I would be one happy camper with a plate of these in front of me. ;)

  9. Tes

    My son will really love this. It looks really simple and delicious :)

  10. Delicious! It’s not often you see a frosted banana treat – and I love frosted treats!

  11. Love the idea of banana bars! Nice that there are not a lot of other flavors in there, just banana. Sometimes bananas are just what I crave. Saved this recipe-yum!5 stars

  12. Aleksandra

    Sounds nice!5 stars
