This banana bread crumb cake could very well be my favorite coffee cake recipe, possibly ever. It has everything a perfect crumb cake should have. We’re talking a moist and tender cake layer swirled with cinnamon sugar, topped with a crumbly, buttery streusel. Only, I make this dessert with one major, game-changing twist: bananas!
What Makes This Banana Coffee Cake So Great
- Put those overripe bananas to good use. I’m always looking for recipes using bananas, especially the ones in my fruit bowl that are barely past their prime. Overripe bananas are perfect for baking banana bread, banana muffins, and, yes, crumb cake!
- Two favorite treats in one. This recipe is a delicious mash-up of banana bread with crumb cake, made in a pan and layered with crunchy streusel. It’s a match made in baking heaven!
- It’s super easy to make. This cake requires simple pantry ingredients and only a handful of steps. It comes together with just 15 minutes of prep.
- It pairs perfectly with coffee or a glass of milk. So you can literally have your cake for breakfast, and eat it, too. Not to mention, this soft, tender crumb cake also makes a fabulous dessert topped with a scoop of ice cream.

Ingredients You’ll Need
Here’s what you’ll need to make this amazing banana coffee cake. I’ve included notes and substitutions here, and you’ll find the full printable recipe with the amounts in the recipe card after the post.
- Bananas – This cake is the perfect occasion to use any ripe or just over-ripe bananas you have, the senior citizens of the bunch.
- Butter – For best results, bring the butter to room temperature.
- Granulated Sugar – When it comes to a moist and fluffy cake, white granulated sugar is always the most reliable. You could also use light brown sugar.
- Dry Ingredients – All-purpose flour, baking powder, and salt. Check the expiration date on your baking powder to make sure it’s fresh.
- Vanilla – Pure vanilla extract will give the best and most natural flavor.
- Milk and Eggs – You can use any kind of milk you’d like. For even more flavor, try substituting regular milk with buttermilk.
For the Streusel
- Butter – Make sure it’s cold from the fridge and cut into cubes.
- Brown Sugar – Light or dark brown sugar both work well here.
- Flour
How to Make Banana Crumb Cake
The secret to this banana cake is in the delicious crumb that’s not just sprinkled over the top, but also swirled throughout the cake. It’s easy to do following the steps below. Scroll down to the recipe card for the printable instructions.


- Mix the batter. Start by whisking flour with baking powder and salt. In a separate bowl, mash your bananas, then mix in the butter, sugar, eggs, and vanilla. Then, add the dry ingredients to the wet ingredients, alternating with the milk, until the batter is just combined.
- Prepare the streusel. In a new bowl, combine the crumb ingredients and cut in the butter with a fork (or a pastry cutter, if you have one).
- Assemble the cake. Now, pour about half of the batter into a greased 9×13″ baking pan. Sprinkle a layer of streusel over the top, and add the remaining batter over the crumb layer. Lastly, top with one last layer of crumb mixture.
- Bake. Bake this banana crumb cake at 350ºF for 50-55 minutes. When a toothpick inserted into the center comes out clean, your cake is done!

Recipe Tips
- Measure correctly. When it comes to baking, the number one misstep is too much flour packed into the measuring cup. If you’re using a measuring cup and not a kitchen scale, rather spoon the flour into the cup and then level it off with a knife, to avoid adding too much flour to the batter.
- Don’t overmix. Another cardinal rule is not to overmix the batter! When mixing in the flour, add it in gradually, alternating with the milk, and mix until the batter is just combined. This will yield the best possible texture when the cake is baked.
- Add a glaze. After the cake has cooled for a few minutes, whisk 1 cup of powdered sugar with 1-2 tablespoons of milk, and drizzle it over the cake.

How to Store
- On the counter. Store this coffee cake airtight at room temperature for up to 2 days.
- Freeze. Wrap the cake tightly in a double layer of plastic wrap or aluminum foil, then store frozen for up to 2 months. Thaw the crumb cake in the fridge overnight and then allow it to come to room temperature before serving.

Hi! Do I need to store this in the refrigerator since the glaze is made with milk?
No, it will be fine at room temperature!
Ingredients in weight please?
I didn’t want to make banana bread *again*…. so I gave this recipe a try for something different . W♥️W!! So delicious!! This is a do again. It’s a great recipe for sharing.
Thanks for uploading your picture! So glad you enjoyed!
Oooo wonder how I can add a pic to mine too.

Made the recipe this morning, cut the sugar in cake almost in half & wish I had thought to add a touch of cinnamon but regardless the outcome was Absolutely the best crumb cake I have ever made! Thank you for the recipe!
So glad you enjoyed!!
You can replace the butter in the cake part with cinnamon applesauce and that cuts the fat and gives you a little cinnamon twist 😉 That’s how we always make it and cut the sugar a 1/4 cup for a half batch.
Could I just use white sugar for the crumb?
Realised you already answered from before but thx
What a great recipe! I only used 1/2 cup of sugar in the batter and halved the crumbs (it was still plenty to put a layer in the middle plus on the top.) I took it to work for a treat and everyone loved it!
No way this recipe works. 2 cups of flour in a 9 x 13 pan. That’s not enough batter. Plus the streusel topping is 2 cups of flour and 2 cups of sugar. What is this? Have a little cake with our streusel. I can’t believe the comments either. No way anyone baked this successfully. Something is amiss in the recipe.
But did you make it?
Nope. I’ve made this recipe twice now, exactly as written, it’s very good and always turns out amazing!
I found it way too sweet…, I mean 5 cups of sugars total? Great idea but if I made it again, I’d have to change it up a lot! And where’s the cinnamon!
Hi!!
I LOVE your coffee cake recipe. It’s perfect in every way. I’m wondering, could I add sour cream to this recipe as well? I enjoy what it does for the coffee cake but wasn’t sure if it would still work here. What do you think?? How much?
It’s not necessary in this one, as the bananas add lots of moisture! Trust me!
I made this today and it’s really good. I read the reviews and reduced the sugar to 1 cup. It was still too sweet and I love sweet. I also didn’t make the icing. Next time I’ll reduce the crumb topping by half and will only put it on top. The bread was moist and delicious. Thanks for a new take on banana “bread”!
So glad you enjoyed and thanks for your feedback…love hearing the switches that are made that work!
Hi, I love this recipe but ran out of light brown sugar. Will there be a huge difference if I use dark brown??
Dark brown will be great!
