This banana crumb cake recipe is one I just randomly threw together and has since become all the rage at my house. I love crumb cakes, as they’re not too sweet, more filling than regular cake, and come with that delicious crumbly topping (you just can’t go wrong). Here are some more crumb cake recipes to check out after you fall in love with this banana crumb cake: cherry crumb cake from cake mix, apple crumble cake, and pumpkin crumb cake.

 In my eternal quest to not waste food, I did this one up as a twist on the old tried and true banana bread as a way to use up those almost-too-ripe bananas. It has been a huge hit at my house and just about flies out of the pan the moment I remove it from the oven. My husband is completely over the moon when I make it now and Bradybug drives me bat-crazy wanting to know when it is going to be done baking. I’ve made it twice this week and it’s only Wednesday!

Fortunately, this banana bread crumb cake is so simple to make using baking essentials, like sugar, milk, self-rising flour, brown sugar, butter, eggs, and vanilla. I bet you have most of these ingredients already at home, right? We’re just going to slowly combine the ingredients to make the cake batter, make the buttery crumb topping using brown sugar, butter, and flour, and add a layer of crumb filling between the cake batter before baking. Oh yes, this banana crumb cake recipe features double the crumble because why not?

The combination of the crumble texture with the moist and tender banana-flavored cake is going to make you come back for more… and more, just like my family. Let’s get baking!

Banana crumb cake ingredients.

Recipe Ingredients

  • Light or dark brown sugar
  • Unsalted butter
  • Eggs
  • Vanilla extract

How to Make Banana Crumb Cake

Add peeled bananas to mixing bowl.

Peel the bananas and add them to a mixing bowl.

I am using four bananas but you can use just three if you like. Now, most people mash their bananas up with a fork for this but we want our crumb cake to be positively infused with banana flavor so we’re gonna liquify these puppies!

Add sugar to mixing bowl and beat together.

Add granulated sugar to the mixing bowl and turn on the electric mixer for a few minutes, until the bananas turn to liquid.

Mix until bananas turn to liquid.

It will look like this.

Add softened butter to mixing bowl and beat again.

Place your softened butter in with the banana mixture and beat that up really well.

It’s important that your butter be softened at room temp for a bit before making this.

Add flour and eggs to mixing bowl.

Now we’re going to toss everything else in there. This includes the flour and eggs…

Add milk to mixing bowl.


Add vanilla to mixing bowl and beat ingredients together.

And vanilla.

Mix all of that up until well blended.

Spray two pans with cooking spray.

Spray two pans with cooking spray.

I am using square cake pans but you can use two loaf pans, a 9×13 baking dish to make a banana sheet cake, or whatever cranks your tractor.

Add brown sugar, butter, and flour in another mixing bowl.

Make the crumb topping

Back at the Duke’s place, Daisy was busy mixing up the crumb topping ingredients…

Place a cup of flour, a stick of butter, and a cup of brown sugar in a separate medium bowl.

Use a fork to mix the crumble topping ingredients together.

You just take a long-tined fork or a pastry cutter and mix it all up together.

Here is your finished product.

Now at this point, it would be awesome if you added in some chopped pecans or walnuts.

I very seldom include nuts in my recipes because it adds a lot of expense and around these here parts, the sheriff (that’d be me) is a cheapskate.

Add 1/4 of the banana cake batter to the pans and top with a 1/4 of the crumb topping.

Pour about 1/4 of your batter into each of your pans and top with 1/4 of your crumb mixture.

Top crumble with remaining banana cake batter.

Top with the rest of your batter.

Then cover that with the rest of your crumbs.

Bake this at 350 until done.

How long it takes will depend on the type of pan you use but to check for doneness just insert a toothpick. If it comes out clean, you’re good to go. If it comes out covered in cake batter, let it cook a bit longer.

I baked my 8×8 cake pans for 45 minutes.

My son just about drove me crazy. “Mama, is the banana cake thing done yet? Can we eat it yet?”

“I’m starving having to smell it!”

It is awfully good.


  • Store leftover banana coffee cake in an airtight container at room temperature for up to 2 days.
  • You can also freeze leftovers for up to 3 months. Thaw at room temperature before serving.

Recipe Notes

  • If you have bananas going bad and don’t want to make banana bread right away, just peel them, smoosh them up with a fork, and freeze them in sealed baggies. Be sure you write on the bag how many smooshed bananas are inside. When you’re ready to make banana bread, let them thaw a bit and toss them in!
  • If you like, top your banana crumb cake with a simple vanilla glaze. You can make this by combining 1 cup of powdered sugar with 12 tablespoons of milk and 1 teaspoon of vanilla extract and drizzling it over the cooled cake.
  • If you’re a fellow fan of cinnamon, add 1 teaspoon of ground cinnamon to the streusel topping. You can also add 1/2 teaspoon of ground nutmeg.
  • For an extra moist cake, use buttermilk instead of whole milk.
  • As mentioned, you can add nuts to the cake. I’d go for chopped walnuts or chopped pecans.
