Ingredients Needed
- 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.
- Step 5: Spread half of the batter in an even layer in a prepared pan.
- Step 6: Evenly distribute the brown sugar cinnamon mixture over the batter.
- Step 7: Add the other half of the coffee cake batter over top.
- Step 8: Sprinkle the crumble over top of the batter.
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.
