Ingredients You’ll Need

3 cups all-purpose flour: The foundation of the cake that provides structure. You can use a gluten-free blend if needed.
1 teaspoon baking soda: This helps the cake rise and become fluffy.
1 teaspoon baking powder: Works alongside baking soda to ensure a light texture.
3/4 teaspoon ground cinnamon: This warming spice gives the cake its signature flavor.
3/4 teaspoon kosher salt: Enhances all the flavors and balances the sweetness.
3/4 cup unsalted butter, at room temperature: Creates a rich flavor and tender crumb; avoid using margarine for best results.
3/4 cup granulated sugar: Sweetens the cake and contributes to texture.
3/4 cup packed brown sugar: Introduces a deeper flavor and moisture.
3 large eggs, at room temperature: Essential for structure and moisture; bring them to room temperature for better incorporation.
2 teaspoons pure vanilla extract: Adds warmth and depth to the overall flavor.
1 1/2 cups mashed brown bananas (about 4 medium bananas): The star ingredient; use well-ripened bananas for maximum sweetness and moisture.
1 1/3 cups buttermilk, at room temperature: Contributes to the cake’s tenderness and flavor; you can substitute with regular milk mixed with a tablespoon of vinegar.
Cinnamon Filling:
- 3/4 cup salted butter, softened: Adds richness to the filling.
- 3/4 cup packed light brown sugar: Sweetens the filling and adds moisture.
- 1 tablespoon all-purpose flour: Helps bind the filling and keep it from being too runny.
- 1 tablespoon ground cinnamon: Intensifies the cinnamon flavor.

Glaze:

2 tablespoons butter, at room temperature: Helps in creating a smooth glaze.
4 ounces cream cheese, at room temperature: Adds a delicious tanginess to the glaze.
2 cups confectioner’s sugar: Sweetens the glaze to balance the cake.
1 teaspoon pure vanilla extract: Enhances the glaze’s flavor.
2 to 3 tablespoons whole milk or heavy cream: To adjust the glaze’s consistency.

How to Make Cinnamon Swirl Banana Cake

Preheat Oven: Set your oven to 350 degrees F and grease a 9×13-inch metal baking pan or line it with parchment paper to prevent sticking. This step ensures an easy release when it’s baked.
Mix Dry Ingredients: In a large bowl, whisk together 3 cups all-purpose flour, 1 teaspoon baking soda, 1 teaspoon baking powder, 3/4 teaspoon ground cinnamon, and 3/4 teaspoon kosher salt. Set this aside, as these will be combined later with the wet ingredients.
Cream Butter and Sugars: In the bowl of a stand mixer (or using a hand mixer), beat 3/4 cup unsalted butter and 3/4 cup granulated sugar with 3/4 cup packed brown sugar until creamy and smooth, about three minutes. Scrape down the bowl occasionally to incorporate everything well.
Incorporate Eggs and Bananas: Add 3 large eggs, one at a time, mixing well after each addition. Then stir in 2 teaspoons pure vanilla extract and 1 1/2 cups mashed ripe bananas until the mixture is combined and smooth.
Combine Wet and Dry Ingredients: With the mixer on low, gradually add the dry ingredients in three intervals, alternating with 1 1/3 cups buttermilk. Start and end with the dry mix. Be careful not to over-mix—just mix until everything is incorporated.
Prepare the Batter: Spread the batter evenly into the prepared pan and set it aside while you make the cinnamon filling.
Make Cinnamon Filling: In a medium bowl, stir together 3/4 cup salted butter, softened, 3/4 cup packed light brown sugar, 1 tablespoon all-purpose flour, and 1 tablespoon ground cinnamon until creamy. This filling should be smooth and spreadable.
Swirl the Filling: Drop small dollops of the cinnamon filling all over the top of the batter, then use the tip of a butter knife to gently swirl the filling into the batter—don’t overdo it; you want to see ribbons of that lovely cinnamon mixture.
Bake: Place the cake in the preheated oven and bake for 30 to 35 minutes or until a toothpick inserted into the center comes out clean. Keep an eye on it; every oven varies in temperature.
Cool: Once baked, remove the cake from the oven and place the pan on a wire rack. Let it cool for about 10 to 15 minutes. It’s ideal for the cake to remain warm when you add the glaze.
Make the Glaze: In a stand mixer or with a hand mixer, beat together 2 tablespoons butter and 4 ounces cream cheese until smooth and creamy. Gradually add in 2 cups confectioner’s sugar and 1 teaspoon vanilla extract, beating until well combined. Add 2 tablespoons of milk and beat for two minutes; if it’s too thick, add more milk, one teaspoon at a time, until you reach your desired consistency.
Glaze the Cake: Spread the glaze over the warm cake, letting it drip down the sides. Cut into squares and serve while still warm for a perfect treat.

Storing & Reheating

To store your leftover Cinnamon Swirl Banana Cake, keep it in an airtight container at room temperature for up to three days. For longer storage, refrigerate it for up to a week. You can also freeze slices individually in freezer-safe bags for up to three months. When reheating, pop your slices in the microwave for about 15-20 seconds. While the texture may change slightly after freezing, warming it up will refresh those delightful flavors.

Chef’s Helpful Tips

Always use bananas that are well-ripened. The more brown spots, the sweeter and more flavorful the cake will be.
Ensure your butter and cream cheese are at room temperature for the smoothest glaze. Cold ingredients can lead to lumps.
Don’t skip letting your cake cool for too long before adding the glaze; the warmth helps it to melt slightly, creating a beautifully drippy finish.
For a more intense cinnamon flavor, consider adding a pinch of nutmeg to the batter or the glaze. It elevates the taste complexity.
If you’d like a less sweet glaze, you can reduce the amount of confectioner’s sugar or add a squeeze of lemon juice for a tart contrast.

Cinnamon Swirl Banana Cake not only combines beloved flavors, but it also offers a wonderful opportunity to create something special with simple ingredients. With its moist texture and delicate sweetness, it’s a great way to make use of overripe bananas while providing your loved ones with something scrumptious. I encourage you to give it a go, explore variations, and enjoy the delightful journey that comes with baking.

Recipe FAQs

Can I use frozen bananas for this recipe?

Absolutely! Frozen bananas are a great way to utilize leftover fruit. Just thaw them first and drain any excess liquid before mashing, and they will work perfectly in the recipe.

What if I don’t have buttermilk?

No worries! You can make a quick substitute by mixing 1 tablespoon of vinegar or lemon juice with a little less than 1 1/3 cups of milk. Let it sit for about five minutes, and you have your homemade buttermilk.

Can I make this cake ahead of time?

Yes, you can! The cake holds up well when stored properly. You can make it a day in advance and store it at room temperature or refrigerate it. Just add the glaze right before serving for the best look and taste.

How do I know when the cake is done baking?

Check for doneness by inserting a toothpick or cake tester into the center of the cake. If it comes out clean or with a few moist crumbs, it’s ready! Remember that slight underbaking can also result in a moist cake, just avoid any wet batter clinging to the toothpick.
