Banana Bread Crumb Cake Ingredients

A complete list of ingredients and amounts can be found in the recipe card below.

Brown sugar: This adds a rich, caramel-like flavor and moisture to the banana coffee cake. Use dark brown rather than light brown sugar.
All purpose flour (AP flour): For best results, measure accurately using the spoon and level method.
Baking powder: Make sure your batch is super fresh for the best rise. Don’t exchange it for baking soda in this recipe.
Mashed ripe bananas: Use very ripe bananas for natural sweetness and moisture. You know, the ones with dark spots on them? Those are the ones!
Butter: At room temperature, so it’s easy to cream with the sugar.
Vanilla extract: Use pure vanilla extract for the best flavor.
Whole milk: Use regular dairy or plant-based – whatever you prefer.

Prepare crumb mixture: In a small bowl, combine brown sugar and flour using a fork or pastry cutter. Add cold butter cubes and work the mixture until it resembles a sandy texture.
Mix dry ingredients: In a medium bowl, whisk together flour, baking powder, and salt.
Prepare banana mixture: In a large bowl, combine mashed banana room temperature butter, granulated sugar, eggs, and vanilla extract until smooth.
Combine wet and dry ingredients: Gradually add half of the flour mixture and half of the milk to the banana mixture, alternating. Mix until just combined after each addition.
Pour batter into pan and bake: Pour the cake batter into a 9 x 13-inch prepared pan, spreading it evenly. Sprinkle over the crumb topping. Bake at 350 degrees F for 50 to 55 minutes or until done.
Cool and serve: Remove the cake from the oven and let it cool on a wire rack for 15 to 20 minutes.

Substitutions and Variations

Gluten-free version: Use gluten-free flour to make gluten-free crumb cakes.
Chocolate chips: Fold 1 cup of chocolate chips into the batter.
Nutty: Add chopped nuts (like chopped pecans or walnuts) to the crumb topping or sprinkle them over the batter before baking.
Milk: Split the milk quantity in the recipe to make it half milk and half sour cream for added tanginess.
Extra fruity: Add a cup of fresh or frozen berries (try blueberries or raspberries) to the batter.
Spiced banana bread crumb cake: Add a teaspoon of ground cinnamon or pumpkin pie spice to the batter for a warm, comforting flavor.
Citrusy: Stir in the zest of a lemon or orange, and perhaps a little orange or lemon juice.
Vegan version: Use plant-based substitutes for the butter, eggs and milk. For example, use vegan butter, flaxseed meal, or chia seeds mixed with water instead of eggs, and almond milk.
Cream cheese frosting: Drizzle a runny cream cheese frosting over the banana crumb cake topping. Add cinnamon to make it a cinnamon swirl icing.

Freezer: Leftovers from baking can also be frozen for up to a month.
Thaw: Let the frozen banana cake recipe come to room temperature from the fridge.

Top Tips

Use ripe bananas: The riper the bananas, the sweeter and more flavorful your banana coffee cake recipe will be.
Room temperature ingredients: Bring butter, eggs, and milk to room temperature before mixing. This ensures even blending and a smoother batter.
Don’t overmix the cake batter: Small pieces of butter in the mixture are normal and will melt during baking, so avoid trying to get them overly blended and stirred through, otherwise you risk ending up with a dense cake.
Prepare the pan properly: Grease your baking pan well with vegetable shortening or baking spray, and consider lining it with parchment paper for easy removal and cleanup.
Even crumb topping: Distribute the crumb topping evenly over the batter to ensure a balanced texture throughout the cake.
Check doneness: Use a cake tester or toothpick inserted into the center of the cake to check for doneness. It should come out clean or with a few moist crumbs, but not wet batter.

Banana Bread Crumb Cake FAQs

Do I have to drain any liquid from defrosting frozen thawed bananas?

There won’t be much liquid to drain, but any additional moisture from any amount of liquid due to thawing (which isn’t much) will bake into the cake.  It might require just a few extra minutes of cooking time.

What if I don’t have ripe bananas? 

You can ripen them in about 6 minutes in a preheated oven at 375 degrees F and cook until the skins outside are black.  This will ripen the bananas for use in this banana bread recipe.  

Can I use unsalted butter for the crumb topping? 

Yes, you can use unsalted butter for the crumb mixture without any problem.

Can I use a food processor to make the crumb topping? 

Yes, just mix the flour and brown sugar using the pulse function, then pulse again when the cold cubed butter is added.  A sandy and slightly wet consistency is the goal.
