Ingredients You’ll Need

3 cups all-purpose flour: This forms the base of your cake, providing structure. Make sure to sift it for lightness.
1 teaspoon baking soda: This helps the cake rise, giving it that fluffy texture we want.
1 teaspoon baking powder: Another leavening agent that ensures your cake is light and tender.
3/4 teaspoon ground cinnamon: The star of this recipe adds warmth and spice.
3/4 teaspoon kosher salt: Enhances all the flavors; don’t skip it!
3/4 cup unsalted butter, at room temperature: Adds richness. Let it soften for best results.
3/4 cup granulated sugar: Sweetens the cake and helps it caramelize beautifully as it bakes.
3/4 cup packed brown sugar: For moisture and a hint of molasses flavor.
3 large eggs, at room temperature: Provide structure and moisture; room temp helps them mix better.
2 teaspoons pure vanilla extract: This elevates the flavor, creating a beautiful aroma.
1 1/2 cups mashed brown bananas (about 4 medium bananas): The key to moisture and sweetness; the riper, the better!
1 1/3 cups buttermilk, at room temperature: Adds a lovely tang and helps create a tender crumb.
3/4 cup salted butter, softened: Used in the cinnamon filling for a rich flavor.
3/4 cup packed light brown sugar: Sweetness and moisture for the swirl.
1 tablespoon all-purpose flour: Helps bind the cinnamon filling.
1 tablespoon ground cinnamon: For that delightful cinnamon swirl effect.
2 tablespoons butter, at room temperature: For the glaze to ensure it spreads smoothly.
4 ounces cream cheese, at room temperature: Adds creaminess to the glaze for that luscious texture.
2 cups confectioner’s sugar: Sweetens and thickens the glaze.
1 teaspoon pure vanilla extract: A touch of flavor for the glaze.
2 to 3 tablespoons whole milk or heavy cream: Adjust the consistency of your glaze.

How to Make Cinnamon Swirl Banana Cake

Preheat your oven: Start by preheating your oven to 350 degrees F. Grease a 9×13-inch metal baking pan or line it with parchment paper to ensure easy removal later.
Mix the dry ingredients: 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. Set this mixture aside.
Cream the butter and sugars: In the bowl of a stand mixer, or using a hand mixer, beat together the 3/4 cup unsalted butter and 3/4 cup granulated sugar along with 3/4 cup packed brown sugar until creamy and smooth—about 3 minutes. Don’t forget to scrape down the sides of the bowl with a spatula to ensure everything is well mixed.
Add eggs and flavorings: Beat in the 3 large eggs one at a time, mixing well after each addition. Then mix in the 2 teaspoons pure vanilla extract. Add the 1 1/2 cups mashed bananas and blend until combined. Scrape down the sides again if needed.
Combine dry and wet ingredients: With the mixer on low speed, gradually add the dry mixture in three rounds, alternating with the 1 1/3 cups buttermilk. Start and end with the dry ingredients to minimize overmixing. You want everything just combined.
Prepare for baking: Spread the cake batter into the prepared pan, and set it aside while you prepare the cinnamon filling.
Make the cinnamon filling: In a medium bowl, mix together 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 it becomes creamy and smooth.
Swirl the filling: Drop small dollops of the cinnamon mixture all over the top of the batter. Use a butter knife to swirl the filling into the batter gently—being careful not to overdo it; you want a nice marble effect.
Bake the cake: Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean. Be sure to check a little early since every oven varies.
Cool the cake: Once baked, remove the cake from the oven and set it on a wire rack. Let it cool for 10 to 15 minutes—don’t let it cool completely; you want it warm for the glaze.
Prepare the glaze: Using a stand mixer or hand mixer, beat together the 2 tablespoons room-temperature butter and 4 ounces room-temperature cream cheese until smooth. Gradually add the 2 cups confectioner’s sugar, 1 teaspoon pure vanilla extract, and 2 tablespoons of milk. Mix until creamy. If it’s too thick, you can add more milk by the teaspoon until you reach your desired consistency.
Glaze the cake: Once the cake is warm, spread the glaze generously over the top. Cut into squares or rectangles and serve warm.

Storing & Reheating

Store any leftover cake at room temperature in an airtight container for up to 2 days. If you want to keep it longer, refrigerate it for up to a week. For freezing, wrap individual pieces tightly in plastic wrap and then place them in a freezer-safe bag for up to 3 months. When you’re ready to enjoy it again, simply thaw at room temperature or pop it in the microwave for about 15-20 seconds to refresh its warm, moist texture. While the flavor remains delightful, the cake will soften a little upon thawing but still be utterly delicious.

Chef’s Helpful Tips

Be cautious not to overmix your batter after adding the flour. It can lead to a denser cake.
Ensure your bananas are super ripe—they should be brown and soft for the best flavor and moisture.
Make sure to have all your ingredients at room temperature. It helps everything combine smoothly.
Flour your measuring cups while measuring brown sugar to get a proper packed measurement.
If you’re aiming for a less sweet cake, you can decrease the amount of sugar in either the cake or the glaze to suit your taste.

There’s something truly special about a warm slice of cake, especially when it’s as comforting as Cinnamon Swirl Banana Cake. Perfectly moist, beautifully swirled, and crowned with a creamy glaze, this cake invites you to savor every bite. Don’t hesitate to make it your own—maybe add some nuts or chocolate chips, or stick with the classic recipe! Whichever path you choose, enjoy the process and the sweet reward that awaits.

Recipe FAQs

Can I use frozen bananas for this recipe?

Absolutely! Frozen bananas work wonderfully in this cake. Just make sure to thaw them before mashing and use them like you would fresh bananas. This can help you avoid waste if you have some ripe bananas sitting in your freezer!

What can I use instead of buttermilk?

If you don’t have buttermilk on hand, you can easily make a substitute by combining 1 cup of milk with 1 tablespoon of lemon juice or vinegar. Let it sit for about 5-10 minutes to curdle, and then it’s ready to use in your recipe.

How do I make the glaze less sweet?

If you find the glaze is too sweet for your liking, consider reducing the powdered sugar and adding a little more cream cheese or butter for balance. A touch of sour cream could also help to cut through the sweetness while adding extra creaminess.

Can I make this recipe gluten-free?

Yes, you can! Just substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. Make sure it includes xanthan gum for the best texture results. Enjoy experimenting with this adaptation!
