Kitchen Tools You’ll Need
You don’t need any fancy equipment to make this Chocolate Chip Banana Coffee Cake, but a few reliable baking tools make the process so much easier. I always recommend using a digital kitchen scale for the most accurate measurements, especially when baking with bananas. A set of mixing bowls and a sturdy silicone spatula make mixing the batter effortless, while parchment paper helps lift the cake out of the pan cleanly for perfect slices. Finally, a quality 9×9-inch baking pan ensures even baking and gives you that soft, tender crumb every time.

Directions
1. Prepare the Pan
Preheat your oven to 350°F.
Line a 9×9-inch square pan with parchment paper or lightly grease it and set aside.
Make the Banana Cake Batter
1. Mix Wet Ingredients
In a large mixing bowl, combine:
- Mashed bananas
- Melted butter
- Granulated sugar
Mix until smooth.
Add:
- Eggs
- Vanilla extract
Mix well, then stir in Greek yogurt.
2. Add Dry Ingredients
In a separate bowl, whisk together:
- Flour
- Baking soda
- Salt
- Cinnamon
Add dry ingredients into wet ingredients and mix until just combined.
Do not overmix.
Fold in chocolate chips.
Make the Cinnamon Sugar Swirl
1. Mix Together
In a small bowl, combine:
- Brown sugar
- Cinnamon
- Salt
Stir until evenly mixed.
Make the Crumb Topping
1. Mix the dry ingredients
In a separate bowl, combine:
- Flour
- Granulated sugar
- Cinnamon
- Salt
Stir until evenly mixed.
2. Cut in the butter
Add the softened butter and use a fork or pastry cutter to work it into the dry ingredients. Keep mixing until the texture looks like coarse, slightly clumpy sand with some larger buttery crumbs throughout.
Set aside while you assemble the cake.
Assemble the Coffee Cake
1. First layer
Pour half of the banana cake batter into your prepared 9×9 pan and smooth it into an even layer.
2. Cinnamon sugar swirl
Sprinkle the cinnamon sugar mixture evenly over the batter. Try to get a nice even layer so every slice gets that cozy swirl.
3. Second layer
Pour the remaining banana batter over the top and gently spread it to cover the cinnamon sugar layer as evenly as possible.
4. Add the crumb topping
Sprinkle the crumb topping evenly over the entire surface of the cake, making sure to cover all edges for that classic coffee cake look.
Bake the Cake
Bake at 350°F for 40–45 minutes, or until the top is golden brown and a knife or toothpick inserted in the center comes out mostly clean (a few moist crumbs are perfect).
The crumb topping should look set and slightly crisp, and the center should feel soft but baked through.
Cool & Serve
Let the cake cool in the pan for at least 20–30 minutes before slicing. This helps the layers set so you get clean, beautiful slices with defined cinnamon swirl and chocolate chips throughout.
If desired, dust lightly with powdered sugar before serving.
Serve warm, room temperature, or even slightly chilled with coffee or milk.
