Ingredients Needed

Labeled ingredients for banana crumb cake.
  • All Purpose Flour
  • Sugar: Use both white sugar and brown sugar for the perfect balance of sweetness.
  • Butter: Softened butter gives the crumble a nice rich flavor.
  • Cinnamon: Pairs well with the sugary sweetness and provides some warmth.
  • Sour Cream: This is the secret to a nice moist coffee cake with a little bit of tangy flavor to balance out the sweetness.
  • Butter: I prefer to use unsalted butter so I can
  • Vanilla extract: Adds an extra dimension of sweet warmth to your cake.
  • Bananas: Commonly used to make banana bread, overripe bananas are also great for making coffee cake!
  • Baking Soda: Provides a nice lift to your crumb cake and prevents it from getting too dense.
  • Salt
  • Powdered Sugar: This is different from granulated sugar so be sure not to use the same kind!
  • Milk: I like to use regular dairy milk, but you could use a non-dairy substitute if you prefer.

How to Make this Banana Crumb Coffee Cake

  • Step 1: For the crumble, add the flour, sugars, butter, and cinnamon in a large mixing bowl.
  • Step 2: Combine until you have large crumbs, then store in the fridge.
  • Step 3: In a separate bowl, combine the wet ingredients for the crumb cake (both sugars, sour cream, egg, butter, vanilla, and mashed bananas).
  • Step 4: Whisk together the dry ingredients in another large bowl (flour, baking soda, and salt) and fold the flour mixture into the wet ingredients.

Recipe Tips

  • The riper the bananas are that you use, the sweeter the result will be.
  • For some extra flavor, add other warm spices like nutmeg or pumpkin spice in the cinnamon sugar layer.
  • You can use either light brown sugar or dark brown sugar.
  • Don’t overmix the batter! You may end up with a more tough or dense coffee cake. Allow refrigerated ingredients to come up to room temperature so the batter comes together more easily.
  • Instead of the homemade icing, you can also dust the coffee cake with some powdered sugar.
  • For a slightly lighter option, use Greek yogurt instead of sour cream and coconut oil instead of butter.
