Ingredients and Substitutions
Base Components
The cake base uses pantry staples combined with ripe bananas. For best results, use bananas with brown spots – they add natural sweetness and moisture:
- Flour: All-purpose flour creates a sturdy yet tender crumb
- Baking powder: Helps the cake rise properly
- Salt: Balances sweetness and enhances flavors
- Bananas: Very ripe ones work best for maximum flavor
- Butter: Provides richness and helps with texture
Crumb Topping Ingredients
The signature crumb layer gives this coffee cake its name:
- Butter: Cold cubes create those perfect pea-sized crumbs
- Brown sugar: Adds caramel notes and helps the topping crisp
- Flour: Binds the crumb mixture together
- Cinnamon and nutmeg: Warm spices that complement the bananas
Glaze Components
While optional, the glaze adds extra sweetness:
- Cream cheese: Creates a tangy base for the drizzle
- Powdered sugar: Dissolves smoothly for the right consistency
- Milk: Thins the glaze to pourable texture

How to Make Banana Crumb Coffee Cake
Step 1: Preparing the Batter
Begin by preheating your oven to 350°F (175°C). Grease a 9×13 inch pan with butter or nonstick spray. The first step involves mixing dry ingredients in one bowl while preparing wet components in another. Whisk together flour, baking powder, and salt. In your mixing bowl, mash those very ripe bananas thoroughly. Add room temperature butter, then sugar, eggs, and vanilla. Blend thoroughly before adding dry ingredients and milk alternately.
Step 2: Creating the Crumb Layer
The secret to perfect crumbs lies in keeping ingredients cold. Cut cold butter cubes into flour, brown sugar, and spices using a pastry cutter or two forks. Stop when the mixture resembles coarse breadcrumbs. For extra texture, squeeze some handfuls gently to create larger clusters.
Step 3: Layering and Baking
Pour half the batter into your prepared pan. Sprinkle half the crumbs evenly across the surface. Add remaining batter, then top with the rest of the crumb mixture. Bake until golden brown (45-55 minutes) or until a toothpick comes out clean. Allow cooling before glazing.
Pro Tips for Success
- Use very ripe bananas – they should have plenty of brown spots
- Don’t overmix batter to keep the cake tender
- Measure flour accurately by spooning into cups
- Let baked cake cool 10-15 minutes before slicing

Flavor Variations
While delicious as written, this versatile recipe welcomes custom additions:
- Add 1/2 cup chopped walnuts to the crumb topping
- Mix chocolate chips into the cake batter
- Replace cinnamon with pumpkin spice blend
