Choosing the Best Bananas
The success of banana bread coffee cake begins with selecting the right bananas. The ideal bananas are heavily speckled or nearly black. As bananas ripen, their starches break down into natural sugars, creating a sweeter flavor and softer texture.
Bright yellow bananas may look attractive, but they lack the sweetness and moisture needed for exceptional banana bread. If your bananas are not ripe enough, place them in a paper bag for a day or two. For faster ripening, bake unpeeled bananas on a baking sheet at 300°F (150°C) for about 15 to 20 minutes until the skins turn black.
Preparing the Streusel
The streusel is one of the defining features of this recipe. It creates both a delicious filling and a crunchy topping.
In a medium bowl, combine:
1½ cups flour
1 cup brown sugar
2 teaspoons cinnamon
¼ teaspoon salt
Mix thoroughly.
Add the cold cubed butter.
Using a pastry cutter or your fingertips, work the butter into the flour mixture.
Continue until the mixture resembles coarse crumbs.
Some pieces should be pea-sized while others remain slightly larger.
These varied crumb sizes create a bakery-style topping.
Mix in the mini chocolate chips.
Place the bowl in the refrigerator while preparing the batter.
Cold streusel creates better texture during baking.
Preparing the Baking Pan
Preheat the oven to 350°F (175°C).
Grease a 9-inch square baking pan thoroughly.
Line with parchment paper if desired.
Leave some parchment overhanging the sides to make removal easier later.
Set aside.
Preparing the Bananas
Peel the bananas and place them into a large bowl.
Using a fork or potato masher, mash thoroughly.
The bananas should become mostly smooth.
A few small lumps are perfectly acceptable.
These tiny banana pieces provide pleasant texture throughout the finished cake.
The mashed bananas should measure approximately 2 cups.
Making the Wet Mixture
To the mashed bananas add:
Granulated sugar
Brown sugar
Eggs
Whisk until smooth.
The mixture should become creamy and well blended.
Pour in the melted butter.
Whisk continuously while adding the butter.
Add sour cream.
Add milk.
Add vanilla extract.
Continue whisking until everything is fully incorporated.
The mixture should look smooth, glossy, and rich.
Preparing the Dry Ingredients
In another large bowl combine:
Flour
Baking powder
Baking soda
Salt
Ground cinnamon
Nutmeg
Whisk thoroughly.
Even distribution of the leavening agents ensures consistent rise and texture.
Combining Wet and Dry Ingredients
Gradually add the dry ingredients to the wet ingredients.
Fold gently using a rubber spatula.
Mix only until combined.
Do not overmix.
Overmixing develops gluten and can create a dense cake.
When only a few streaks of flour remain, add:
Semi-sweet chocolate chips
Mini chocolate chips
Fold gently until evenly distributed.
The batter should be thick and luxurious.
Assembling the Coffee Cake
Spread half of the batter into the prepared pan.
Use an offset spatula to smooth the surface.
Sprinkle half of the chilled streusel evenly over the batter.
Cover with the remaining batter.
Carefully spread the second layer.
Sprinkle the remaining streusel over the top.
Ensure every section is covered.
This layered method creates a ribbon of cinnamon streusel throughout the center while leaving plenty on top for crunch and visual appeal.
Baking Process
Place the cake on the center oven rack.
Bake for 60 to 75 minutes.
The cake is done when:
The center feels set.
A toothpick inserted into the center comes out with only a few moist crumbs.
The top appears golden brown.
The edges pull slightly away from the pan.
If the top browns too quickly, tent loosely with aluminum foil.
Avoid opening the oven repeatedly during baking.
Stable heat promotes even rising.
Cooling the Cake
Remove the pan from the oven.
Place it on a cooling rack.
Allow the cake to cool for 30 minutes in the pan.
Carefully lift it out if using parchment paper.
Continue cooling for at least another hour.
Proper cooling allows the crumb to set completely.
Preparing the Vanilla Glaze
In a bowl combine:
Powdered sugar
Vanilla extract
Milk
Whisk until smooth.
The glaze should flow easily from a spoon.
Drizzle over the cooled cake.
Allow the glaze to set before slicing.
