Got ripe bananas to use up? This banana crumb cake is the perfect way to use them! I am such a sucker for a good coffee cake, so when I had some extra bananas to use up, I knew I wanted to make this banana cake.

The base is similar to my apple coffee cake and my cherry coffee cake with the streusel and warm cinnamon flavors. As a professional baker, I wanted to make sure the cake had a dense but moist texture to it and when you bit into it, you were hit with the crunchy texture on top.

Kind of like these bakery style banana muffins but made into a cake.

The banana flavor is subtle but adds a sweetness that takes this coffee cake to the next level.

Secret to a moist coffee cake

The key to a moist banana coffee cake is using ripe bananas and not over mixing the batter. Over mixing banana coffee cake will result in a tough and dry texture. The buttermilk also really helps to enhance the moisture. If you dont have it, use whole milk instead, or a mixture of 50% milk to 50% yogurt.

Springform pan

I like to make coffee cakes in a spring form pan bc it makes it so much easier to cut and serve. If you dont have one, you can make it in a 9″ round cake pan, just be sure to spray it well with baking spray.

How to make banana coffee cake

Prepare for baking: Preheat the oven to 350F. Spray a 10” springform pan with baking spray and set aside.

Recipe tips

  • Make sure your bananas are ripe- the riper the banana the more banana flavor you will get in your cake!
  • A coffee cake is done when a toothpick inserted into the center comes out clean or with moist crumbs attached.
  • Be sure not to over mix the batter. Mix until just combined for a tender and fluffy cake.
  • Make sure all of the refrigerated ingredients are at room temperature (except for the butter for crumb topping) before beginning the recipe to ensure a smooth cake batter.
  • If you don’t have buttermilk on hand, you can easily make your own by adding one tablespoon of white vinegar or lemon juice to regular milk called for in the recipe and letting it sit for five minutes.

Ingredients

For crumb topping:

  • 1 cup all purpose flour, 120g
  • ½ cup brown sugar, 107g
  • ¼ cup sugar, 50g
  • ½ tsp cinnamon
  • ¼ tsp kosher salt
  • ½ cup butter, unsalted, cold, diced small.

For Cake

  • ½ cup butter softened, 113 g unsalted
  • 1 cup granulated sugar, 200g
  • 1 egg, large
  • 1 cup bananas, ripe mashed
  • 1 tsp vanilla extract
  • 2 cups all purpose flour, 240g

For Optional Glaze:

  • ½ cup confectioners sugar, 56g
  • 1 tbsp cream

Equipment

Instructions
 

  • Make the crumb topping. In a small bowl combine the 1 cup flour, 1/2 brown sugar, 1/4 cup granulated sugar, 1/4 -1/2 tsp cinnamon, and 1/4 tsp salt.
  • Use a pastry cutter to cut in the ½ cup butter or pinch the butter into the mixture with your fingers gently until small clumps are formed no larger than the size of a pea. Place in the fridge while you make the cake.
  • Preheat the oven to 350°F. In the bowl of a hand or stand mixer fitted with the paddle attachment, cream the butter for one minute. Scrape down the sides and add the 1 cup sugar. Cream for 2 minutes on medium speed until light and fluffy.
  • Scrape the bowl again and add the egg, mashed bananas and 1 tsp vanilla extract. Mix on medium speed until combined, about 1 minute.
  • In a separate bowl combine the 2 cups flour, 1 tsp baking powder, ½ tsp kosher salt ½ tsp cinnamon and ¼ tsp baking soda. Mix lightly with a fork or whisk to combine.
  • Alternate adding the dry ingredients with the buttermilk starting and ending with the dry ingredients- ⅓ at a time- mixing in between each addition.
  • Spray a 10” springform pan with baking spray and pour in the batter.
  • Top with the crumb topping and bake for 50-55 minutes on until the cake is no longer jiggly.
  • When the cake is cooled, mix together the ½ cup confectioners sugar with 1 tbsp cream and drizzle all over the cake.

Notes

The darker and more spotty the bananas you use, the sweeter they will be!
