Easy Banana Cake Recipe
I love this banana cake recipe because we always have the ingredients on hand. I bet you do too! And if your bananas aren’t ripe yet, you can put them in a brown bag to hurry along the process. I know you want to make this cake ASAP!
I also love this cake because there is nothing fancy about it. There are no bells and whistles attached to this cake. Thank goodness because I can’t decorate a cake for the life of me:) Don’t worry though, this cake still impresses. The cake and frosting are amazing on their own!
Peanut Butter Banana Cake
Let’s take a moment to talk about the peanut butter frosting. I am normally not a huge frosting person but put a bowl of peanut butter frosting in front of my face and I want to dive in head first. I thought about not even frosting the cake, but I knew the wait would be worth it. I LOVE the banana and peanut butter combo! It is perfection.
Try this Banana Cake!
The cake is perfect the day it’s made, but I personally think it is even better the second day. The cake is even more moist and delicious! So if you need a dessert that can be made ahead of time, this is your recipe!
Use your brown bananas to make this Easy Banana Cake with Peanut Butter Frosting. And if you find yourself eating the cake straight from the pan with a fork, don’t be surprised:)

Easy Banana Cake with Peanut Butter Frosting
Ingredients
For the Banana Cake:
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter at room temperature
- 1 1/2 cups granulated sugar
- 2 large eggs
- 1 cup plain Greek yogurt
- 1 teaspoon vanilla extract
- 3 ripe bananas peeled and mashed (to equal 1 cup)
For the Peanut Butter Frosting:
- 1/2 cup unsalted butter at room temperature
- 1/2 cup creamy peanut butter
- 3 cups sifted powdered sugar
- 1/3 cup milk
- 1 teaspoon vanilla extract
Instructions
- Preheat oven to 350 degrees F. Grease a 9x13 pan and set aside.
- In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
- In a large bowl, cream together the butter and sugar until creamy and smooth, about 3 minutes. Beat in the eggs, one at a time, then stir in the Greek yogurt and vanilla extract. Mix in the mashed bananas.
- Slowly add the dry ingredients and mix until flour disappears. Spread cake batter evenly into the prepared pan.
- Bake for 25-35 minutes, or until a toothpick inserted into the center comes out clean. Allow cake to cool completely.
- While the cake is cooling, make the peanut butter frosting. In the bowl of a stand mixer, beat the butter and peanut butter on high until smooth. Slowly add the powdered sugar, ¼ cup at a time. Beat on high until powdered sugar is incorporated. Add the milk and vanilla extract. Beat until frosting is smooth and desired consistency.
- Frost the banana cake with peanut butter frosting. Cut into squares and serve.
- Note-store covered cake on the counter for 3-4 days. I think the cake gets better as it sits.

This cake looks heavenly! Such a delicious combo!
Yum! That frosting looks so fluffy and sweet!
I made the banana cake this weekend for a family get-together and everyone enjoyed it. I found the peanut butter frosting just a tiny bit….bitter? I am no baking expert, so just wonder if it could be the vanilla, or even the confectioner’s sugar. Any thoughts? Thanks.
oh my word. . this looks so delicious! Pinned and can’t wait to try!
I’ve recently discovered that you can throw brown bananas in your freezer and defrost them on your counter quickly when you want to make some delicious banana bread. This comes in handy in the summer when I have a bunch of bananas that browned too quickly in the heat and then I return to baking in the fall. 🙂
Made this tonight, had to sample the cake when it came out of the oven, delish! Looking forward to frosting it and sharing with my family tomorrow. Thanks Maria for another great recipe to use up those bananas!
I made this last night. Brought it to work today. Everyone likes it. It has a lot of banana flavor. The frosting is very good. As someone above mentioned, it took about 30 minutes to bake in a 13 x 9 pan. If you use a sheet pan, it would take a shorter time. This is a great way to use up brown bananas. It would be awesome with cream cheese frosting, too.
Made this cake last night and this will be my “go to” dessert recipe from now on!! So amazingly simple and delicious! Everyone raved about it and had to send them all home with slices! You have the best recipes, my FAVORITE site to go to for fantastic food! Thank you for sharing!
Can you halve the recipe? What size pan/baking time? Also I have regular yogurt and no sour cream…is there any way to sub this? Thanks!,
Wow. This looks so freakin good!!!!! Dying to make this! 🙂
I made this cake yesterday and its delicious!! I made a couple of small changes.. I didn’t have any plain Greek yogurt so I used sour cream instead. Then I added a cup of chocolate chips to the cake batter before baking because my husband kept saying it needed chocolate. It turned out great! This recipe is definitely a keeper!
Can you substitute vanilla greek yogurt for the plain yogurt? Would you then just cut out the vanilla extract?
Yes, I would leave the vanilla extract in still.
I made this cake last night and I almost died, it was soooo good!
I’d like to make this recipe as cupcakes for my son’s 1st birthday. Any suggestions (cook temp/time)? Thanks!
I want to make this recipe but I wanted to make sure that “3 cups of powered sugar” in the frosting is not a mistake. 3 cups? Sounds like a huge amount. Thanks.
I made this today, and my two younger boys gobbled it up! They can be quite picky. I too wanted something different than the usual banana bread. Thanks so much!
You are welcome! I am glad your boys loved it!
There is no way this cake was done in 25 minutes more like 45 minutes
I made this again today, at least the fifth time. Still a huge hit! LOVE this recipe!
Yay! It’s one of my favorites too!
I made this a while ago and I came back now to post my review. It’s very delicious! I’ve made two of your cake recipes so far and they’ve been a hit. Looks like I’m sticking to this website for many more awesome recipes.
Loved the recipe. Thanks for the recipe. I was very happy after reading the recipe. The recipe is very good. I really appreciate that you shared very delicious recipe. The banana adds a special flavor to it. At last i want to say that the overall recipe is very good and delicious.
This cake was awesome. Made it for a family dinner and everyone loved it. Will definitely be making it again! Thank you for sharing the recipe.
So happy you enjoyed the banana cake!
Love this recipe!
I halved the sugar for the cake and it was still super sweet! I think I will omit added sugar In the cake and let the frosting do it thing.
I only have a 6×12” pan so halved the frosting recipe and it was just the right amount to cover the cake.
My cake cracked at the top while baking (which usually happens to the banana cakes I bake). Is is because of the size of the pan I used? Any tips on how to prevent it from cracking?
Hi! If we only have salted butter is that okay? Should we omit the salt in the dry ingredients? What about the frosting? Will it be okay? Thanks!
Sure, you can use salted butter. It will be slightly more salty but still good. I love a kick of salt:)
Always need good ripe banana recipes.This looks delicious
I love making cake recipe next one is I gonna cook is this banana cake
Just made this cake as I am not always a fan of banana bread so wanted something different. I used vanilla greek yogurt, turned out good, it is a bit dense but I expected that with being a banana cake. I only used 2 cups of powdered sugar and a bit more peanut butter, this turned out perfect, not too sweet.
This is one of the best recipes I have ever had! My grandma and me made this and put in everything but the dry ingredients in the oven. We put it in for 25 minutes and realized at 11 minutes remaining we had forgotten all the dry ingredients. In the end, we took the batter out of the oven, mixed in the dry and it still worked. I think that it is better the way we did it. Btw the frosting is the best❤
Hi Maria! Can you give me some advice if I’d like to halve this recipe? I’m wondering about which baking pan size I should use and also about adjusting the baking time? Thank you so much.
If you want to halve the recipe, use a 8×8 inch pan. Check 10 minutes early to be safe!
this is super delicious and moist but tomorrow you said it’s better!! I can’t wait!
It’s such a great cake!
