Ingredients You’ll Need

3 cups all-purpose flour: This forms the base of your cake. Make sure to sift it before measuring for a lighter texture.
1 teaspoon baking soda: Gives your cake its rise, ensuring it’s fluffy and soft.
1 teaspoon baking powder: Aids in the leavening process. Don’t skip it!
3/4 teaspoon ground cinnamon: This warms the flavor profile, enhancing the banana.
3/4 teaspoon kosher salt: Balances the sweetness perfectly; sea salt can work too!
3/4 cup unsalted butter, at room temperature: Creates a tender crumb and rich flavor.
3/4 cup granulated sugar: Sweetness that complements the brown sugar.
3/4 cup packed brown sugar: Adds moisture and a hint of caramel flavor.
3 large eggs, at room temperature: Ensure even mixing and a good rise.
2 teaspoons pure vanilla extract: For warm undertones; avoid imitation extract.
1 1/2 cups mashed brown bananas: Ripe is best! About 4 medium bananas, mashed well for moisture.
1 1/3 cups buttermilk, at room temperature: Keeps the cake tender and adds depth to the flavor.
3/4 cup salted butter, softened: This is for the cinnamon filling, adding richness.
3/4 cup packed light brown sugar: Sweetness for the filling, which creates that heavenly swirl.
1 tablespoon all-purpose flour: Helps bind the filling together.
1 tablespoon ground cinnamon: Adds more of that inviting flavor to the swirl.
2 tablespoons butter, at room temperature: For the glaze, ensuring it’s easy to spread.
4 ounces cream cheese, at room temperature: Provides creaminess to the glaze.
2 cups confectioner’s sugar: Sweetens the glaze beautifully; sifting will give a smoother finish.
1 teaspoon pure vanilla extract: For flavor in the glaze, bringing it all together.
2 to 3 tablespoons whole milk or heavy cream: To adjust consistency of the glaze.

How to Make Cinnamon Swirl Banana Cake

Preheat the Oven: Set your oven to 350 degrees F. Grease a 9×13-inch metal baking pan or line it with parchment paper, making cleanup a breeze.
Create the Dry Mix: In a large bowl, whisk together the 3 cups all-purpose flour, 1 teaspoon baking soda, 1 teaspoon baking powder, 3/4 teaspoon ground cinnamon, and 3/4 teaspoon kosher salt. This ensures even distribution of all dry ingredients.
Mix the Butter and Sugars: In a stand mixer or using a hand mixer, beat the 3/4 cup unsalted butter and 3/4 cup granulated sugar along with 3/4 cup packed brown sugar until the mixture is creamy and smooth, about 3 minutes. Be sure to scrape down the bowl with a spatula as needed.
Incorporate the Eggs and Vanilla: Add in 3 large eggs one at a time, mixing well after each addition. Then stir in the 2 teaspoons of pure vanilla extract and the 1 1/2 cups of mashed brown bananas, blending until combined.
Combine with Dry Ingredients: With the mixer on low, add your flour mixture in three parts, alternating with the 1 1/3 cups of buttermilk until everything is well combined. Try not to overmix; we want a tender crumb.
Prepare the Swirl: Spread the batter evenly into the prepared pan, then set it aside while you make the cinnamon filling.
Mix the Cinnamon Filling: In a medium bowl, mix the 3/4 cup softened salted butter, 3/4 cup packed light brown sugar, 1 tablespoon all-purpose flour, and 1 tablespoon ground cinnamon until creamy. This will be the swirly goodness!
Swirl in the Filling: Drop small dollops of the cinnamon filling on top of the batter. Using the tip of a butter knife, gently swirl the filling into the batter.
Bake: Place the cake in the oven and bake for 30 to 35 minutes or until a toothpick inserted in the center comes out clean. Each oven is unique, so start checking at 30 minutes.
Cool the Cake: Remove your cake from the oven, setting the pan on a wire rack for 10 to 15 minutes. Don’t let it cool completely; you’ll want it warm when adding the glaze.
Prepare the Glaze: In a mixer, beat together the 2 tablespoons butter and 4 ounces cream cheese until smooth. Gradually add in the 2 cups confectioner’s sugar, 1 teaspoon vanilla extract, and 2 tablespoons of milk, beating until you reach a smooth, spreadable consistency. If it’s too thick, add more milk a teaspoon at a time.
Glaze Your Cake: Spread the glaze over the warm cake. Cut into squares and serve.

Storing & Reheating

To keep your Cinnamon Swirl Banana Cake fresh, store it at room temperature in an airtight container for up to 3 days. If you want it to last longer, refrigerate it, where it can stay good for about a week. For longer storage, feel free to freeze individual pieces wrapped in plastic wrap or in a freezer-safe container for up to 3 months. When you’re ready to dive back in, pop it in the microwave for about 15-20 seconds, and you’ll enjoy that warm comforting dessert as if it just came out of the oven!

Chef’s Helpful Tips

Be sure your butter and eggs are at room temperature, as this helps them incorporate better for a fluffier cake.
Avoid overmixing the batter once you’ve added the dry ingredients; this can lead to a dense texture.
For an even more pronounced banana flavor, use very ripe bananas when mashing.
If you accidentally overbake the cake, try to drizzle an extra layer of glaze over it to add moisture.
You can also experiment by adding nuts or chocolate chips for additional texture and flavor.

Cinnamon Swirl Banana Cake is a wonderful blend of flavors that everyone will adore. The soft, moist crumbs paired with a delightful cinnamon sweetness and creamy glaze make this cake irresistible. I encourage you to experiment with the recipe—maybe add a touch more cinnamon if you’re a spice lover, or throw in some pecans for a bit of crunch. No matter how you choose to customize it, this warm cake is bound to become a favorite in your home. Grab your ingredients, and let’s bake something delicious together!

Recipe FAQs

Can I make this cake ahead of time?

Absolutely! You can prepare the cake a day in advance. Just store it in an airtight container at room temperature. When you’re ready to serve, add the glaze right before cutting into it. This way, it stays fresh and delicious.

What can I use instead of buttermilk?

If you don’t have buttermilk on hand, you can make a quick substitute! Just add 1 tablespoon of white vinegar or lemon juice to a cup of milk and let it sit for about 5 minutes. This will give you a similar tangy flavor and texture.

How do I know when the cake is done?

Check for doneness by inserting a toothpick into the center of the cake. If it comes out clean or with a few moist crumbs attached, your cake is ready. Keep an eye on it, because baking times can slightly vary depending on your oven.

Can I freeze the glaze?

While it’s best to make the glaze fresh, you can store it in an airtight container in the fridge for up to a week. If you’ve left it out to sit for a while, make sure to re-whip it before spreading it on your cake to achieve that silky smooth texture again.

Instructions

Preheat the oven to 350 degrees F. Grease a 9×13-inch baking pan or line with parchment paper, then set aside.
In a large bowl, mix together the flour, baking soda, baking powder, ground cinnamon, and salt. Set aside.
Using a stand mixer or hand mixer, beat the unsalted butter and granulated sugar until creamy, about 3 minutes. Scrape down the bowl as needed.
Add the eggs one at a time, followed by the vanilla extract. Mix in the mashed bananas until combined, scraping the bowl as necessary.
Gradually add the dry ingredients in three parts, alternating with the buttermilk. Mix until just combined without overmixing.
Pour the batter into the prepared baking pan and set aside while preparing the cinnamon filling.
For the cinnamon filling, mix together softened butter, brown sugar, flour, and cinnamon in a medium bowl until smooth.
Dollop the cinnamon filling over the batter and swirl gently with a butter knife to create a marbled effect.
Bake for 30 to 35 minutes or until a toothpick inserted in the center comes out clean; check the cake early to be safe.
Once baked, remove from the oven and let cool for 10 to 15 minutes on a wire rack, ensuring the cake remains warm for glazing.
To prepare the glaze, beat the softened butter and cream cheese until smooth. Mix in the confectioner’s sugar, vanilla, and 2 tablespoons of milk; blend for 2 minutes or until smooth. Adjust the consistency with more milk if needed.
Spread the glaze over the warm cake, slice into squares, and serve.

Notes

Ensure bananas are well-mashed for even distribution in the batter.
Do not overmix the batter as it can affect the cake’s texture.
Serve the cake warm for the best flavor with glaze.
