How to make the BEST Banana Coffee Cake!

Hey guys! Sam here again from Sugar Spun Run with another sweet treat for you!

Recently I’ve been doing a lot of baking with bananas after finding myself faced with a mile-high pile of well-browned bananas in my house. They were just past their prime and desperately needed to be baked into something or they would shortly need to be thrown out (and my freezer was and always is way too full to even consider storing them there).

I made batch after batch of my favorite banana muffins and passed out more slices of cream cheese frosted banana cake than I can even count, but eventually I wanted to try something different and this recipe for Banana Coffee Cake was born!

How to Make Banana Coffee Cake

The #1 tip is to find the ripest bananas you can! The browner and spottier they are the better — this is going to give your Banana Coffee Cake the best flavor. Mash them up well (you can use a potato masher, or even just a fork) and add them to your butter, sugar, eggs, and other wet ingredients.

Stir together your dry ingredients in a separate bowl, and then use a spatula to gently fold the dry ingredients into the wet. Take care not to over-mix the batter here!

Finally, pour your banana coffee cake batter into a greased and floured 9×9 pan and prepare your streusel topping, which is what really puts this coffee cake over the top!

How to Make Streusel Topping

There are a number of different ways to make streusel topping, but my preferred method is to start with melted butter. Many recipes use cold butter, but for this particular streusel, the melted butter makes for a nice buttery crumb that pairs so well with the banana cake.  Use a fork to stir your dry streusel ingredients in with the melted butter.

Take care not to overwork the streusel mixture, or you’ll end up with a paste! You want the mixture to resemble coarse crumbs that you can use your hands to drop evenly over your banana coffee cake.

A delicious banana coffee cake made with ripe mashed bananas and a crisp, crumbly, streusel topping!

Ingredients

Streusel

  • 6 Tablespoons butter melted
  • 1 1/4 cup all-purpose flour
  • 1/2 cup light brown sugar tightly packed
  • 1/3 cup sugar
  • 3/4 teaspoon ground cinnamon

Banana Coffee Cake

  • ¾ cup unsalted butter softened to room temperature
  • 3/4 cup sugar
  • 3 very ripe bananas mashed (1 ½ cups)
  • 2 large eggs lightly beaten (room temperature preferred)
  • teaspoon vanilla extract
  • 2 Tablespoons sour cream
  • 11/3 cup all-purpose flour
  • ¾ teaspoon baking powder
  • 1/2 teaspoon baking soda
  • ½ teaspoon ground cinnamon
  • ½ teaspoon salt

Glaze (optional)

  • 1/2 cup powdered sugar
  • 2-3 teaspoons milk

Instructions

  1. Preheat oven to 350F and lightly grease and flour a 9x9 baking pan. Set aside.
  2. Combine butter and sugar in the bowl of a stand mixer (or in a large bowl and use an electric mixer). Beat until well-combined, then stir in mashed bananas.
  3. Add eggs, stirring well after each addition, and then add sour cream and vanilla extract and stir well.
  4. In a separate, medium-sized bowl, whisk together your flour, baking powder, baking soda, cinnamon, and salt.
  5. Gradually add the dry ingredients to wet, stirring until completely combined (be sure to scrape down the sides and bottom of the bowl). I prefer to do this with a spatula to avoid over-mixing the batter.
  6. Pour batter evenly into prepared 9x9 pan. Prepare Streusel.

Streusel

  1. Melt butter in a medium-sized bowl on 10 second increments (stirring between) until just melted (you don't want it to be too hot).

  2. Use a fork to whisk together your flour, sugars, and cinnamon. Pour melted butter over mixture and use a fork to stir until combined (mixture should be crumbly).
  3. Sprinkle streusel evenly over batter.
  4. Bake on 350F for 35 minutes, or until centers spring back to the touch and a toothpick inserted in the center comes out with few moist crumbs or clean.
  5. Allow to cool before drizzling with glaze (if using) and slicing and serving.

Glaze

  1. If desired, make glaze by whisking together powdered sugar and milk. Drizzle over cooled banana coffee cake.

  1. This was really good but a strange thing happened. The night I made it, I wasn’t happy and was going to throw it out because I thought it was dry. The next night when I came home from work, I tried it nefore I threw it out…it was so incredibly moist. It was like a totally different cake and I loved it!!!
