Banana Coffee Cake with Chocolate Chip Streusal

I had a bunch of overripe bananas that I didn’t want to go to waste, so I was going to make some banana bread. That’s what you do with overripe bananas, right? But I couldn’t help thinking how boring that is. I have a great banana bread recipe from my mom, but that’s the point, everyone and their mom already has a great banana bread recipe on hand. So I made it my mission to find something different to make with overripe bananas and boy did I hit gold. This banana coffee cake recipe is AWESOME! I’ll be making this again and again. If I have kids, they will have this recipe from me, just like I have my mom’s banana bread recipe. That’s how good this stuff is.

The one fault issue nit pick, I have with the recipe is that it’s actually too good. Seriously. It’s almost too rich to eat in the morning. That could just be me, though. I’m used to eating very light in the mornings, and the amount of chocolate in this recipe is just way too much for me. Maybe it would be more appropriate for dessert with some decaf coffee?

Next time I will definitely be reducing the amount of chocolate in the recipe and even the amount of sugar. The recipe posted below will reflect the new amounts. You could probably even take out the chocolate chips altogether if you wanted, but I think they really make the dish, so I wouldn’t want to take them out completely.

Breakfast | Servings: 6
Prep time: 20 min | Cook time: 45 min | Total time: 1 hour 5 min


  • 3/4 to 1 cup chocolate chips (depends on how chocolatey you want it)
  • 1/2 to 3/4 cup packed brown sugar (depends on how sweet you want it)
  • 1/2 cup chopped walnuts (optional, I didn’t put these in mine)
  • 1 tbsp. cinnamon
  • 1 1/2 cups flour
  • 3/4 tsp. baking soda
  • 3/4 tsp. baking powder
  • 1/4 tsp. salt
  • 3/4 cup sugar
  • 1/2 cup (4 oz. – 1 stick) unsalted butter, room temperature
  • 1 large egg
  • 1 1/3 cups mashed very ripe bananas (about 3 large)*
  • 3 tbsp. buttermilk or plain yogurt (I used the yogurt)

*Your bananas should be as ripe as possible. I’m not talking a few black spots, I’m talking almost completely black on the outside. The riper your bananas the better the flavor of the cake will be, this applies to making banana bread as well.


  1. Preheat oven to 350°F. Butter and flour 8x8x2-inch metal baking pan.
  2. Stir chocolate chips, brown sugar, walnuts (if using), and cinnamon in small bowl until well blended; set streusal aside.
  3. Sift all purpose flour, baking soda, baking powder, and salt into medium bowl.
  4. Using electric mixer, beat sugar, room temperature butter, and egg in large bowl until fluffy. Beat in mashed bananas and buttermilk. Add dry ingredients and blend well.
  5. Spread half of batter (about 2 cups) in prepared baking pan. Sprinkle with half of streusal. Repeat with remaining batter and streusal.
  6. Bake coffee cake until toothpick inserted into center comes out clean, about 45 minutes. Let cool for at least 10 minutes.
