This banana bread coffee cake is a cinnamon banana cake baked in a bundt pan. It has a brown sugar and cinnamon filling and is topped with a cinnamon crumble. To sweeten the cake, it has a vanilla glaze on top. This banana cake tastes like banana bread with a ton of cinnamon. This is a brunch must bake.
How To Make Banana Cake Batter
This cake is the most moist cake! It takes 4 ripe bananas to get a strong banana flavor, but that also helps make it so moist!
- Mix dry ingredients together- In a separate bowl, mix all the dry ingredients together. Don't forget the cinnamon!
- Beat butter and sugar- To get a good rise on the cake, beat the butter and sugar for 3 minutes. It will get very light and fluffy.
- Add in ripe bananas and sour cream- This is what makes the cake so moist. The bananas should be brown spotted before you mash them. I use a potato masher to mash the bananas.
- Add in eggs- Next, the eggs should be added one at a time on low. Make sure to scrape the bowl, so the butter is all mixed in.
- Mix in the dry ingredients- Then, add in the dry ingredients a little at time. The texture of the batter is similar to banana bread!
- Pour half of the batter- Next, pour half of the batter in the pan. Then, top with cinnamon filling. Pour the rest of the batter on top!
How To Keep The Cake From Sticking
The worst issueis when a bundt cake stays in the pan when you try to flip it out!
To prevent this, spray the bundt pan with baking non-stick spray. Spray the pan very well! That baking spray is magic.
Once the cake is done baking, let it sit in the hot pan for 10 minutes. Then, transfer to a cooling rack. It should come right out.
Cinnamon Crumble
Now it is time for the coffee cake part of this cake! What makes a coffee cake is all the crumble on top!
First, mix all the dry ingredients together. Then, pour in the melted butter. Use a fork to stir. Stop once only large crumbles remain. Don't over mix!
Then, spread the crumble on a cookie sheet and bake.
When it comes out of the oven, it will appear melted. Don't worry, that is how it supposed to look. Use a rubber spatula to stir and break up the crumble. Let it cool completely. It will harden into a crumble.
Decorating The Cake
When I was recipe testing the cake, I wondered how I would get the crumbles to stay on top of the cake. The answer is the glaze!
Start by pouring the glaze on top of the cake. Use all of the glaze! While it is still wet, pat the crumbles on top. Get as many on top of the cake as you can!
Can This Cake Be A Sheet Cake?
Yes! You can bake the banana bread coffee cake in a 9X13 inch pan. Pour half of the cake batter into the pan and top with the cinnamon filling. Then, pour the rest of the cake batter on top.
Instead of baking the crumble separately, pour the crumble right on top of the cake batter. Then, bake for 25-30 minutes.
Storing The Cake
The banana bread coffee cake should be stored at room temperature in an air tight container or a cake carrier. It will last up to 5 days.

Kathy Harlow says
I am not sure when to add the “ 1/4 cup Unsalted butter melted for topping the cake” based on the directions...is this after you sprinkle on the crumb topping?
Stephanie Rutherford says
It is before you sprinkle the topping. So it helps it to stick to the cake.
Micah says
So does the melted butter go on before the glaze? I think there is a mistake In the recipe.
Stephanie Rutherford says
Hello!
I realized when I was writing the recipe I thought I needed the melted butter to allow the crumbles to stick. But the glaze works just fine for that. I just forgot to delete it. I fixed it now. Just top with a glaze and the crumbles.
Micah says
Thank you for your reply. My crumble is going into the oven right now!
