Banana Crumb Cake

Banana Crumb Cake

What do you get when you inject bananas into a coffee cake?  Including a ribbon of delicious crumble running through it?  And adding a sweet drizzle of frosting on the top?  You get the most delicious Banana Crumb Cake EVER! 

I had been toying around with banana breads for the longest time…I must have tried 8 different versions and while a few came close to perfection, I still wasn’t totally feeling it until I found this recipe from Cookies & Cups.  Now, to be fair, this is not a banana bread.  It isn’t dense;  it’s deliciously moist.  You don’t slice it like bread;  you square it up like coffee cake.  You don’t eat it just for breakfast; you eat it anytime your little heart desires (which will be all the time!).

Banana Crumb Cake

Basically, you are making a cake batter that includes mashed up bananas.  You are also making a crumb filling (and you’ll also top the cake with it).  Put some of the batter in your pan, top with crumb filling, add more batter, and top that with the crumb filling.  Bake this entire concoction.  Cool it, frost it, eat it!!!

Oh, don’t forget to top the frosting with a drizzle of Salted Caramel Sauce (click this link) if you really want to blow it out of the park!!!  Cheers!

Banana Crumb Cake

Makes: 12 servings

Prep Time: 15 minutes

Bake Time: 50-55 minutes

Total Time: 1 hour & 20 minutes



  • 2 cups all-purpose flour
  • 3 tsp baking powder
  • 1 tsp salt
  • 3 ripe bananas
  • 1/2 cup unsalted butter, room temperature
  • 2 cups granulated sugar
  • 2 eggs
  • 1 tsp vanilla
  • 1 cup milk

Crumb Filling and Topping:

  • 1 cup cold butter, cubed
  • 2 cups light brown sugar
  • 2 cups flour


  • 1 cup powdered sugar
  • 1–2 Tbsp milk

Optional (but you really should make this!):



Preheat oven to 350°F. Spray a 9×13 baking dish with cooking spray, set aside.

In a medium bowl whisk together flour, baking powder and salt. Set aside.

In a large bowl mash bananas until they become liquified. Mix in butter until combined and then stir in sugar, eggs and vanilla until mixed well. Stir in milk and flour until combined.

Crumb Filling/Topping:

Prepare crumb filling/topping by combining all the ingredients together cutting them together with a fork or pastry cutter until a coarse crumb forms.

Pour 1/2 of the batter into the prepared pan. Top with 1/3 of the crumb mixture. Cover the filling with the remaining batter and top with remaining crumb mixture.

Bake for 50-55 minutes until the center is set and a toothpick comes out clean. Cool for 10 minutes.

Mix powdered sugar and milk together and drizzle on top.

Can be served warm or at room temperature with Salted Caramel Sauce, if desired.
