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.

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.

Does it matter if it is salted or unsalted butter?
I use salted, but you can use whatever you would like!
Absolutely love this recipe! Definitely a recipe to keep!
One thing though, I added about 1-2 tablespoons of cinnamon.
Great addition!
If use white sugar for the crumb will it still be the same
It won’t be the same, no, but it will work 🙂
This is an amazing recipe, TRY IT!! It’s probably the best cake i’ve ever made! The texture of the crumble, with the moist and cake-y inside is just PERFECT! I tried it once and everyone loved it, we had it with some fresh raspberries yumm!
I’d like to try it again but the only ripe bananas I have are frozen do you think its fine to use them? or would unripe bananas work?
Nour, I use frozen bananas all the time I just let them thaw out and get to room temperature or your butter won’t cream very good! Hope this helps! I just put my banana cake in the oven can’t wait to try it.
This is a very yummy cake. It is very sweet. I bet you could use 1/2 of the sugar and 2/3 of the crumbs and it would still be awesome. The icing just sends it over the top with sweetness, it is not necessary. But it does make it look pretty. Thanks for the recipe!
So glad you enjoyed it!!
I made the recipe all in half since it’s only me & my daughter will eat this during this quarantine time. Used only 1/4c of the white sugar since there will be more sugar on crumbs. Added 1tsp of cinnamon to the crumbs. I will take out maybe 1/4c off ingredients on the crumbs since it seems too much. Wish didn’t used all the crumbs. Very moist. We still love it since it’s something different from banana bread that we always make.
I’ve made this recipe once and it was a hit! However I had to borrow a friends glass pan to bake. Do you think it’s possible if I bake this in a nonstick cake pan or a loaf pan?
I didn’t mean to post this twice, I’m sorry.
Yes you could. YOu will need to adjust the bake time slightly. If you’re using a nonstick pan it will cook a little quicker 🙂
Absolutely delicious. Everyone loved it. I may try to reduce the sugar a little next time.
Does it need to be refrigerated?
It’s fine at room temperature!
Delicious! I did reduce the white sugar to one cup, added 2 tsp cinnamon to the crumb, and left off the glaze. It was still a little sweet so I plan to reduce the crumb next time. Love the banana flavor though!
I made this dessert and honestly it’s one of the best cakes Ive ever eaten! My family loved it so much I’m going to make it again for my dad’s birthday at the end of the month. P.s I also added A teaspoon of cinnamon. Next time I’m going to use caster sugar as opposed to Granulated and 1/2 a cup less, as I did find it a tad bit too sweet at times.
