Banana Sheet Cake

Banana Sheet Cake

There’s something about a “sheet cake” that has a charm of its own. It screams out good down-home cooking. When that Banana Sheet Cake is rich, moist, bursting with banana flavor and topped with a (not too sweet) cream cheese frosting, you’ll know it’s true.

I fell in love with this Banana Cake at my first taste. A co-worker, Laura S. used to bring this into the office and people began digging in as soon as she got there, eating it for breakfast. When I asked, Laura generously shared the recipe – and had extra copies tucked in her purse because she’d been asked so many times.

Because a sheet cake like this easily cuts into many portions, it feeds a crowd and I cannot tell you how many Church funeral luncheons and potlucks I have brought this to over the years. It does require a “special” pan but I have a few other sheet cake recipes, so you’ll put it to good use. Mine has a lid, which I love.

Although this is a super easy cake, to make, there are a few things to know for success:

  • The mixing method is odd – I have considered tinkering to make conform to “modern” mixing methods, but frankly, it’s such a fantastic cake that I just don’t dare. Make sure your butter is at the perfect temperature, stir your flour to lighten it before measuring and make sure to use the full amount of banana.
  • The banana is critical – it has to be very speckled and almost completely brown and has to be measured just right, 1 1/2 cups, which usually comes out to about three and a half to four bananas. Fudge it a bit and your Banana Cake it will be ok, measure it just right and it will be sublime! Mash the banana very well, to an almost liquid state and use a spatula to get every bit of it.
  • Be sure not to over bake this supremely moist cake. Because it’s so shallow, timing is critical. You’ll not be able to judge by color and it may brown unevenly (I turn it about halfway through.) It is done when the corners are just pulling away from the edges by a hair and when it is touched in the center, ever so gently, it slowly springs back up. As with all cakes, set your timer early and check it every few minutes until you get the timing down.

Laura’s original recipe called for walnuts, which we usually just omit because they’re not really a fave. Pecans would work, too, and a reader recently suggested mini chocolate chips. We tried the chips, and like them, but really our favorite version is just plain with the frosting. That’s probably just us, though.

This recipe is really a family fave, and often requested by friends and relatives when I ask them what kind of cake they want for their birthdays! I have to laugh at that a bit because I’m always willing to make some extravagant layer cake at the drop of a hat! Try it and you’ll see why. 🙂

Banana Sheet Cake with Cream Cheese Frosting

This Banana Sheet Cake is chock full of banana flavor and has a not too sweet Cream Cheese Frosting.

  • Author: mollie kirby adapted from Laura
  • Yield: 24 servings 1x


  • 1 2/3 cups sugar
  • 1/3 cup butter, softened and at room temperature
  • 2 eggs (extra-large preferred)
  • 1 teaspoon vanilla
  • 2 1/4 cups flour
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 1 1/2 cups mashed banana (about 3 1/2 large)
  • 2/3 cup buttermilk
  • 2/3 cup chopped walnuts, pecans or mini chocolate chips
  • Cream Cheese Frosting


Preheat oven to 350 degrees. Grease and flour jelly roll pan, 10 1/2 by 15 inches. Set aside.

Beat sugar and butter in a large bowl. (Will look “crumbly.”) Add in eggs and vanilla.

In another bowl, mix flour, baking soda and salt with a whisk until well blended. Add to butter mixture, making sure to use a spatula to mix in flour from bottom. It’s ok if it’s not completely smooth.

Beat in mashed bananas and buttermilk at low-speed. Stir in walnuts, pecans or chips by hand.

Bake for 20 to 30 minutes (the larger size pan bakes more quickly) until the corners are just pulling away from the sides of the pan and the top when gently pressed in the center, springs back. Turn halfway through baking.

    My family just loves this cake. My daughter, who loves banana bread, said it’s better than any banana bread she’s ever had. I made another banana sheet cake today. I want to freeze it. Goodies call my name so I have to get them out of sight. I’m not sure if it’s better to freeze it unfrosted? Or frosted? I’m not sure which would be best. How do you think the frosting will be if it’s frozen say for a month?

    • FrugalHausfrau

      Deborah I;m sorry to be replying late. I think you can go either way; although I haven’t specifically tried this cake frozen with frosting, I have had other cakes with cream cheese frosting and thought they held up well (if I could resist eating them half frozen, lol!)


    • Debbie

      You can freeze cakes with this frosting. I make carrot cake with cream cheese frosting and freeze it.
      Defrost in refrigerator

    I come from a long line of bakers and I’ve made many banana cakes and bread during my life. This is the most moist and tender ever! Absolutely delicious and I followed the recipe exactly as written except for the nuts since I was out. I highly recommend this easy and amazing cake. Thanks for the great recipe!

    • FrugalHausfrau

      Hi Carolyn, it’s my pleasure and thanks for stopping back and giving it your stamp of approval!! 🙂 I appreciate it!!

    Once a week I make treats for the middle and high school my grandkids go to. Made this last week to raves all around. Thanks for a great recipe that makes enough for a crowd. Not too many of those around. It’s nice not to have to double or triple the recipe. :o)

    • FrugalHausfrau

      Thanks Gwen, I’m so glad everyone liked it! Doubling or tripling can get dicey sometimes!, believe me, I know! It’s also nice to know there are still places where you can bring homemade treats to school. Its been banned in Minnesota for years.

    • I stopped over and I will leave a comment there! You’ve made it look so gorgeous with those chocolate chips. And I love that you left a link and that story gets passed on; not everyone does that. 🙂

    I make this cake at least once a month. It’s what I use my “over ripe” bananas on instead of throwing them away. It’s always delicious and my family tears it up. I made a couple of changes for my family’s liking. Instead of a cream cheese frosting, I use just a powdered sugar and milk glaze (only because I didn’t have cream cheese a couple of times) and it was still good, I also omit the nuts, just because I don’t care for nuts. Will continue to make you recipe for years to come and pass the recipe on to my children.

    • Good morning, Cherie. I can’t tell you how nice it is to hear that you guys have enjoyed this so much. (I omit the nuts too, lol!) I love passed down recipes the most because there’s a little history behind them and good memories. It makes them special. 🙂

      To tell the truth, sometimes cream cheese frosting can seem a bit heavy, especially in the summer; I’m going to have to try a glaze next time!

    I have made this cake several times and it always comes out delicious. My favorite banana cake recipe. However, I’m not a fan of nuts so I omit the nuts. This is a must try ❤️😎

        I did use chopped chocolate chips in place of nuts…worked perfectly. Cake was a big hit. A little left over, so I froze those pieces. Froze well and tasted fine when defrosted. Thanks for a great recipe for crowds.

        • Thanks, Carol, for checking back! I’m so glad everyone liked it and I’ll be making mine with chocolate chips next time! I’m glad to know about the freezing, too, because it IS a big cake so I don’t always want to make it for my smaller family – and we’d like to have it more often!
