Ripe bananas take center stage in this wonderfully soft banana cake, creating a tender crumb and naturally rich banana flavor in every slice.
The texture sits beautifully between banana bread and traditional cake: moist and satisfying like banana bread, yet light, soft, and lifted like a classic cake.
Smoothly mashed or pureed bananas help keep the finished cake especially even and tender, while buttermilk contributes to its soft texture.
Cinnamon adds a gentle warmth that complements the sweetness of the bananas without overpowering them.
The cake batter combines familiar pantry staples, including all-purpose flour, baking powder, baking soda, butter, sugar, eggs, buttermilk, ripe bananas, and vanilla extract.
Together, these ingredients create a balanced cake that is rich without feeling overly heavy.
Once baked and cooled, the cake receives a generous layer of homemade cream cheese frosting.
The frosting brings a smooth, creamy finish, combining softened cream cheese and butter with vanilla and powdered sugar, while a tiny amount of salt helps balance the sweetness.
Baked in a 9×13-inch pan, this banana cake makes 16 slices, making it a practical choice for sharing.
Whether served as an afternoon treat, dessert, or centerpiece for a casual gathering, its moist banana crumb and creamy frosting make it especially inviting.
Classic Moist Banana Cake
Ingredients
Equipment
Method
- Prepare the Pan: Preheat the oven to 350°F. Grease a 9×13-inch pan thoroughly with non-stick cooking spray and set it aside.
- Prepare the Bananas: Puree or very smoothly mash 3–4 large ripe bananas. Measure the prepared bananas afterward to ensure you have exactly 1½ cups (340g). Pureeing the bananas is recommended for a smoother, less chunky cake texture. Set aside.
- Combine Dry Ingredients: In a small mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, and cinnamon until evenly combined.
- Cream Butter Sugar: In a large mixing bowl, beat the room-temperature butter and granulated sugar with an electric mixer for 1–2 minutes, until the mixture becomes fluffy.
- Add Wet Ingredients: Add the eggs, buttermilk, pureed bananas, and vanilla extract to the butter mixture. Beat with the electric mixer until the ingredients are combined.
- Incorporate Dry Mixture: Gradually add the flour mixture to the wet ingredients, mixing just until the flour is incorporated. Avoid mixing beyond this point.
- Fill the Pan: Transfer the prepared batter to the greased 9×13-inch pan and spread it into the pan.
- Bake the Cake: Bake at 350°F for 40–55 minutes, or until a toothpick inserted into the center comes out clean.
- Cool Completely: Allow the baked cake to cool before applying the cream cheese frosting.
- Whip Cream Cheese Butter: Place the softened cream cheese and softened butter in a mixing bowl. Beat with an electric mixer on medium speed for 1–2 minutes, until whipped and fluffy.
- Add Sugar Vanilla: Add the vanilla extract, powdered sugar, and salt. Beat on low speed for 1–2 minutes, scraping down the sides of the bowl as needed, until everything is fully incorporated.
- Adjust Frosting: If the frosting is too thick, add a dash of milk or heavy cream and beat until the frosting becomes creamy.
- Frost the Cake: Spread the prepared cream cheese frosting evenly over the completely cooled banana cake.
Notes
- Use very ripe bananas for the fullest banana flavor and a naturally moist cake.
- Measure the bananas after pureeing or mashing to ensure you have 1½ cups (340g).
- Pureeing the bananas produces a smoother, less chunky texture in the finished cake.
- Bring the butter to room temperature before beating it with the sugar so the mixture can become fluffy.
- Add the flour mixture gradually and mix only until incorporated to avoid unnecessarily overmixing the batter.
- Check the cake at the earlier end of the 40–55 minute baking range with a toothpick inserted into the center.
- Let the cake cool completely before frosting so the cream cheese frosting stays properly spreadable.
- If the frosting seems too thick, add only a small dash of milk or heavy cream and beat until creamy.
Chef’s Secret
For the smoothest banana cake texture, pay particular attention to how the bananas are prepared.
The source specifically recommends pureeing the ripe bananas rather than leaving them chunky.
After pureeing, measure out the full 1½ cups (340g) required for the batter rather than relying on the number of bananas alone, since banana size can vary.
This gives you the intended balance of banana, flour, buttermilk, and other ingredients.
Once the banana mixture is added, gradually incorporate the dry ingredients and stop mixing as soon as the flour disappears.
This approach preserves the soft, tender character that distinguishes this cake from a denser banana bread.
Serving Suggestions
Serve slices of the cooled banana cake generously covered with cream cheese frosting.
For a simple presentation, cut the cake into 16 slices and serve as an afternoon treat or dessert.
The creamy frosting provides the main finishing element, while the banana and cinnamon flavors make the cake satisfying on its own.
For gatherings, arrange the frosted slices on a serving platter and keep the presentation simple so the soft cake and creamy topping remain the focus.
Conclusion
This banana cake combines the comforting flavor of ripe bananas and cinnamon with a soft, moist cake texture and creamy cream cheese frosting.
With straightforward ingredients and a simple preparation method, it makes a generous 9×13-inch dessert that is well suited to sharing.
