Irresistible Flavor: The combination of ripe bananas and cinnamon creates a cozy, comforting taste.

Diet-Friendly Options: Easily adaptable for gluten-free or dairy-free diets with simple substitutions.

Ingredients You’ll Need

3 cups all-purpose flour: This forms the foundation of the cake’s structure. If you’re gluten-free, you can substitute with a 1-to-1 gluten-free flour blend.
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: Adds that warm, spicy flavor that pairs beautifully with bananas.
3/4 teaspoon kosher salt: Enhances all the flavors and balances the sweetness.
3/4 cup unsalted butter, at room temperature: Provides richness and moisture; you can also use coconut oil for a dairy-free version.
3/4 cup granulated sugar: Sweetness in the batter to counterbalance the natural sugars in bananas.
3/4 cup packed brown sugar: Adds a deeper, caramel flavor.
3 large eggs, at room temperature: Binds everything together and adds moisture; room temperature helps the eggs incorporate more easily.
2 teaspoons pure vanilla extract: For an extra depth of flavor.
1 1/2 cups mashed brown bananas (about 4 medium bananas): The star ingredient, adding natural sweetness and moisture. Make sure they’re very ripe for the best flavor.
1 1/3 cups buttermilk, at room temperature: Adds richness and acidity, which helps activate the baking soda for a lighter cake.
3/4 cup salted butter, softened: This is used for the cinnamon filling, adding extra creaminess.
3/4 cup packed light brown sugar: This makes the filling rich and sweet with that molasses flavor.
1 tablespoon all-purpose flour: Helps thicken the cinnamon filling just a bit.
1 tablespoon ground cinnamon: For actual swirls that taste like cinnamon rolls.
2 tablespoons butter, at room temperature: Used to smooth the filling.
4 ounces cream cheese, at room temperature: Adds a rich, tangy flavor to the glaze.
2 cups confectioner’s sugar: For sweetness in the glaze; it gives that silky finish.
1 teaspoon pure vanilla extract: Enhances the glaze’s taste.
2 to 3 tablespoons whole milk or heavy cream: To adjust the glaze’s consistency to your preference.

How to Make Cinnamon Swirl Banana Cake

Preheat the Oven: Preheat your oven to 350 degrees F (175 degrees C). Grease a 9×13-inch metal baking pan or line it with parchment paper to ensure easy removal.
Mix the 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. This helps to evenly distribute the leavening agents throughout the flour.
Cream the Butter and Sugars: In the bowl of a stand mixer (or using a hand mixer), beat together 3/4 cup unsalted butter and 3/4 cup granulated sugar and 3/4 cup packed brown sugar until creamy and smooth, about 3 minutes. Don’t forget to scrape down the sides with a spatula to incorporate everything evenly.
Add Eggs and Bananas: Beat in 3 large eggs, one at a time, followed by 2 teaspoons pure vanilla extract and 1 1/2 cups mashed brown bananas until combined. Scrape down the bowl as needed to ensure all ingredients are mixed uniformly.
Combine with Dry Ingredients and Buttermilk: With the mixer on low speed, gradually add the dry ingredients in three parts, alternating with 1 1/3 cups buttermilk, until just combined. Make sure to end with the dry ingredients and avoid over-mixing to keep the cake tender.
Prepare the 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 should be smooth but remains somewhat thick for swirling later.
Transfer Cake Batter: Spread the prepared batter evenly into the greased pan and set aside.
Swirl the Filling: Drop small dollops of the cinnamon filling over the batter. Using the tip of a butter knife or a skewer, swirl the filling into the top of the batter, creating a marbled effect.
Bake: Bake in your preheated oven for 30 to 35 minutes or until a toothpick inserted into the center comes out clean. Keep an eye on it, as oven temperatures can vary slightly.
Cool Before Glazing: Once baked, remove the cake from the oven and place it on a wire rack to cool for about 10 to 15 minutes. Don’t allow it to cool completely; the glaze is best used on a warm cake.
Make the Glaze: In your mixer, beat together 2 tablespoons butter, at room temperature, and 4 ounces cream cheese until smooth. Add 2 cups confectioner’s sugar and 1 teaspoon vanilla extract, then gradually mix in 2 tablespoons milk. Beat until smooth. If it’s too thick, add more milk one teaspoon at a time until reaching your desired consistency.
Glaze the Cake: Once the cake has cooled slightly, spread the glaze evenly over the top. Cut into squares and serve warm or at room temperature for the best experience.

Storing & Reheating

Store leftover Cinnamon Swirl Banana Cake at room temperature for up to 3 days. Keep it in an airtight container to maintain its moisture. If you want to prolong its shelf life, you can refrigerate it for up to a week. For longer storage, wrap it tightly and freeze for up to 3 months. When ready to enjoy, simply thaw at room temperature or warm individual slices in the microwave for about 10-15 seconds. You might notice a slight change in texture after freezing, but a warm slice with a cup of coffee is still pure bliss!

Chef’s Helpful Tips

To avoid a dense cake, make sure all your ingredients are at room temperature before you begin.
For an extra moist cake, don’t skip the buttermilk, as it adds richness and helps with leavening.
Always check your cake a few minutes before the suggested baking time to avoid overbaking, as all ovens vary.
If you find your glaze too thin, simply add more confectioner’s sugar until the desired thickness is achieved.
Feel free to add chopped nuts or chocolate chips to the batter for added texture and flavor!
This cake can also be made ahead of time and frozen. Just remember to glaze it once it’s thawed.

Cinnamon Swirl Banana Cake captures the essence of home baking with its comforting flavors and delightful sweetness. It’s a perfect canvas for creativity—try adding your favorite spices or mix-ins to make it your own. Each slice evokes a warm nostalgia, making any moment feel special. Enjoy baking and sharing this cake with those you love, and immerse yourself in the joy it brings!

Recipe FAQs

Can I use frozen bananas in this recipe?

Absolutely! Frozen bananas work wonderfully in Cinnamon Swirl Banana Cake. Just thaw them completely, drain excess liquid, and mash them well. They need to be very ripe for the best flavor, just like fresh ones!

How do I know when the cake is done baking?

Check for doneness by inserting a toothpick into the center of the cake; if it comes out clean or with a few moist crumbs, it’s ready. Also, look for slightly golden edges and a fragrant aroma wafting from the oven.

Can I make this cake dairy-free?

Yes! To make it dairy-free, substitute the buttermilk with a plant-based milk mixed with a little vinegar or lemon juice to mimic the acidity. Use dairy-free butter and cream cheese for the glaze as well.

What can I do if my cake turns out dry?

If your cake feels dry, it might be due to overmixing or overbaking. To fix this, ensure you mix just until combined. If it’s already baked, consider serving it with a scoop of ice cream or a drizzle of warm glaze to add moisture.

Preheat the oven to 350 degrees F and prepare a 9×13-inch metal baking pan by greasing it or lining it with parchment paper.
In a large bowl, whisk together the all-purpose flour, baking soda, baking powder, ground cinnamon, and kosher salt. Set aside.
In a stand mixer or using a hand mixer, beat together the unsalted butter, granulated sugar, and packed brown sugar until the mixture is creamy and smooth, approximately 3 minutes. Scrape down the bowl as needed.
Add the eggs one at a time to the butter and sugar mixture, followed by the vanilla extract and mashed bananas. Mix until combined, scraping down the sides if necessary.
With the mixer on low, gradually incorporate the dry ingredients in three parts, alternating with the buttermilk. Finish with the dry ingredients and do not over mix.

In a medium bowl, combine the softened salted butter, light brown sugar, all-purpose flour, and ground cinnamon until smooth and creamy.
Dollop the cinnamon filling evenly over the top of the cake batter and use the tip of a butter knife to swirl it into the top of the batter.
Bake for about 30 to 35 minutes, checking with a toothpick inserted into the center until it comes out clean. Adjust baking time based on your oven.
Remove the cake from the oven and allow it to cool on a wire rack for 10 to 15 minutes. It should be warm when adding the glaze.
