What You’ll Need
Here are the ingredients you’ll need to make banana sheet cake at home. See the recipe card located at the bottom of the post for full instructions.
- Butter– I use salted butter for my recipes, unsalted works fine too.
- Granulated Sugar– This fine white sugar adds sweetness to the sheet cake.
- Sour Cream– Use full fat sour cream for the recipe.
- Ripe Bananas– Make sure your bananas are brown spotted and ripe for best results.
- All-Purpose Flour– Flour is the main dry ingredient in the banana sheet cake recipe.
- Ground Cinnamon– Cinnamon is used as part of the cinnamon roll flavors of the recipe.
- Baking Soda– Baking soda helps the sheet cake rise during baking.
- Salt– I use kosher salt in my cooking and baking.
- Brown Sugar– I use light brown sugar for the recipe.
- Cream Cheese– Use full fat cream cheese for the recipe.
- Powdered Sugar– Powdered sugar is used to make the icing.
- Milk– Ue 2% milk or higher for the recipe.
How To Make Banana Sheet Cake
Preheat Oven and Prepare Baking Sheet. Preheat oven to 350 degrees and line a half sheet baking pan with parchment paper.
Cream Butter and Sugars. Place butter, sugar, sour cream and bananas into stand mixer, mixing until well combined.
Dry Ingredients. Add flour, baking soda, cinnamon and salt, mixing until well combined. Transfer to prepared baking pan, spreading evenly.
Cinnamon Drizzle. Place melted butter into a medium mixing bowl, add brown sugar and cinnamon mixing well.
Drizzle Cinnamon Butter Mixture Over Batter. Drizzle over cake batter then take a knife to swirl throughout.
Bake. Bake for 35-40 minutes, or until baked through.
Prepare Icing. When cake is done baking, prepare brown butter icing. Brown butter in a small saucepan until bubbly and browned. Place softened cream cheese into a large mixing bowl. Pour browned butter over cream cheese whisking until smooth. Slowly add powdered sugar and almond milk until smooth.
Drizzle Icing Over Warm Sheet Cake. Drizzle over warm cake and spread evenly. Let cool completely then cut into squares and serve room temperature or chilled.
Mashed bananas and sour cream up next.
Dry ingredients up next then give a good mix.
Pour Banana Bread Cake Batter Into Baking Pan
Pour right into a half sheet size baking pan lined with parchment….don’t use wax paper like I did. Big mistake 🙂
Drizzle your cinnamon sugar mixture on top.
Swirl Cinnamon Roll Drizzle
Run a knife through and give it a swirl 🙂
Ahhhh, perfect. Time to bake!
Seriously the best. Swirls of buttery cinnamon sugar throughout the whole cake.
Prepare Your Cinnamon Roll Icing
Time for the cream cheese brown butter icing! Pour your hot browned butter over softened cream cheese and whisk like crazy. This will take a couple minutes to get smooth, don’t worry 🙂 Just keep whisking.
Add your powdered sugar in batches and whisk until thick, but not too thick.
The icing should still drizzle over your warm cake like so. Spread it evenly with an offset spatula and let cool.
How To Serve
Serve this banana sheet cake warm or room temperature cut into squares. It’s great for parties and easy to transport.
Leftovers
Store any leftover sheet cake in an airtight container in the refrigerator for up to 3 days.

Wow! This looks amazing! My kids won’t eat bananas, wonder if I could substitute canned pumpkin??
Can you halve the recipe for a smaller pan/serving? Looks amazing!!!!
How can I print this recipe
Could i do this is 9×13? If so what would i change?
Hi Jenny: I tried to make this and make it low carb, using Almond flour in place of the regular 1 1/2 cup cups Gold Medal. What a MESS. The cake turned out VERY OILY, I guess from all the fat in the Almond Flour (Bobs). Literally oil floting on top of the cake. So wondering if you have tried to make this Low Carb, and if so, what did you do? Also I spread the batter in my “half sheet” pan, which is 16.5 inches by 11.5 inches and it was really thin. In this case, the cake actually tore it was so thin, as I was trying to blot the oil from off the top of it. So if you have any suggestions for converting to low carb, I would appreciate it. I wound up throwing the cake away after I already had the frosting ready to go. So will make Carrot bars tonight to use up the frosting 🙂 Thanks for any help you can give, and if you’ve not tried a Low carb version, I understand. Thanks, Barry Moody
This is the BEST cake! I’ve made it a few times with RAVE reviews! Thanks for sharing!
This cake was delicious. We did not add a frosting on top as it was perfect without. will make again for sure.
What size pan did you use? She says a half sheet is 12×24 but I don’t think that’s right. I really want to make but want to half it and can’t decide what size pan to use. Thanks
Can this recipe be done in a 9× pan?
This recipe is sickeningly sweet. Would not make again.
Are there eggs in cake batter?
Simply Amazing! Where has this been all my life ?

Say no to hate, say no to SEWER, say no to p DONALD TRUMP and EMMA WATSON and Tatylor Swift !! Deport racism today ahm.
This is Definetly not the place for you political rants.n
SO bad for you, but SO yummy! Had to use some past-due bananas. Did not have sour cream, but substituted Greek yogurt and it worked fine. Thanks for another option for using up those old bananas.
I also would like to know if this can be frozen. I have read every comment and your post several times, seeing where several people have asked this but I don’t see a response. I always have a Happy Birthday Jesus cake with my 7 grandchildren on Christmas Day, to begin the festivities focusing on Jesus, the reason for the season! I would like to know if this can be frozen in preparation for our Happy Birthday Jesus celebration.
This looks and sounds sooooo yummy! Thank you for sharing.
Blessings to you and your precious family.
I could not find your answer for can this be frozen. Would love to take this to family reunion.
Can I make this but do it as muffins, just follow the recipe?
Delicious!! I made it exactly as written. However, I found that it was done baking in less than half the instructed time. My oven temperature is right on, so I’m not sure why it was done so quickly. Either way, it was a hit at work!
