Banana Crumb Cake
This Banana Crumb Cake is what I make when I notice bananas sitting on the counter with more brown spots than yellow left on them. Instead of tossing them in the freezer and forgetting about them, I can have this cake mixed and in the oven in about 15 minutes, all in one bowl. It bakes up soft and moist with plenty of banana flavor, and the brown sugar crumb topping gives it that bakery-style finish without adding much work.

I’ve taken this cake to potlucks, sliced it for breakfast, and served it for dessert more times than I can count. It makes enough to feed a crowd, holds up well if you bake it ahead, and freezes without any trouble. It’s a simple, old-fashioned banana cake that fits right into a Southern kitchen and always gets eaten.
Before You Get Started
- Use very ripe bananas: The more brown spots, the better. Overripe bananas mash and blend easier and give the cake a deeper banana flavor.
- Soften the butter: Soft butter blends smoothly into the banana mixture. If your butter is cold, microwave it at low power in short bursts so it softens without melting.
- Pick your pan size: You can use two loaf pans or two 8×8 pans. If you use loaf pans, expect the bake time to lean closer to the longer end.
- Make crumbs that hold together: When cutting the butter into the topping, aim for a mix of small crumbs with a few pea-sized pieces. That gives you a topping that bakes crisp and buttery instead of powdery.
Recipe Ingredients

- sugar
- ripe bananas
- milk

- unsalted butter
- eggs
- vanilla extract
How to Make Banana Crumb Cake
1. Prepare the Batter
Start by peeling the bananas and placing them in a large mixing bowl. Add the granulated sugar and mix until the bananas are completely liquefied.
Add the butter and continue mixing until it’s well blended with the banana mixture. Stir in the flour, eggs, milk, vanilla extract, and nuts if using. Mix just until everything is combined.




2. Prepare the Pans
Spray two loaf pans or two 8×8 baking pans with cooking spray.

3. Make the Crumb Topping
In a medium bowl, add the flour, brown sugar, and butter. Use a long-tined fork or pastry cutter to cut the butter into the mixture until the largest pieces are about the size of peas, with smaller crumbs throughout.


4. Assemble the Cake
Pour one quarter of the batter into each pan to form the base layer. Sprinkle one quarter of the crumb topping evenly over each layer.
Divide the remaining batter between the pans, then top with the remaining crumb mixture.



Bake
Bake at 350°F for 45 minutes to 1 hour, until a toothpick inserted into the center comes out clean.
Allow the cake to cool slightly before slicing.


Storage
Store leftover banana crumb cake in an airtight container at room temperature for up to two days. For longer storage, freeze tightly wrapped slices for up to three months. Thaw at room temperature before serving.

Notes for Making Banana Crumb Cake
- Freeze bananas ahead: When bananas start turning brown, mash them and store in freezer bags labeled with how many bananas are inside. Three bananas per bag makes baking easy later.
- Add a glaze: For an even more indulgent cake, top your banana crumb cake with a simple vanilla glaze. Make by combining 1 cup of powdered sugar with 1–2 tablespoons of milk and 1 teaspoon of vanilla extract and drizzling it over the cooled cake.
- Spice it up: Add cinnamon or nutmeg to the crumb topping for extra warmth.
- Extra moist cake: Buttermilk can be used in place of regular milk.
- Make your own self-rising flour: For each cup of all-purpose flour, add 1½ teaspoons baking powder and ½ teaspoon salt.

Hey Christy…Bountiful is
A great choice. I am writing my first comment to you from my new iphone. Had to get a new phone seeing as my old phone got run over last week but that’s another story. Love the crumble cake. I make banana crumble regularly so this crumble cake is very similar. If I have over ripe bananas I also make a smoothie with some bananas,milk and a small amount of Greek yoghurt. Ok this just made me remember back to when I was a kid my friend and I dressed up as the Bananas in Pyjamas for our book fair. Well I hope you xan read this ok!
Oh I remember bananas in pajamas. Although I was in high school when they were popular I still had one because I thought they were cute.
What an absolutely perfect name! Bountiful….I love it!! We never named our house, ‘cuz it wouldn’t have come when we called it anyway.
How amazing that you had yet “another Divine moment” with Tina like you did with the Taste of Ga cookbook/Dixie Cornbread email from me. Just keep on doing what you are doing, girl. We all appreciate the lovely pics of the new flowers, sunroom, kitchen.
Honey’s staff loves banana nut bread, muffins when I send in food to the office. THIS is the next “to go” recipe and yes, I will make two. Weee.
Love ya!
Perfect Perfect Perfect!
This looks so good and much better than regular cake!
That looks good but bananas never last long enough round here. Edward loves “lar-lars” as he calls them and eats 2 or 3 a day when we buy them. Matter of fact he gave his toothless 6 month old sister one last night. He also tries to feed her biscuits, cereal, and string cheese.
I made the banana crumb cake tonight and everyone LOVED it. Thank you so much for taking the time to teach us how to cook so many delicious things for our family. My husband could not believe how great this cake tasted and it made the house smell scrumptious!!!
Thank you so much…
