How to Make Cinnamon Swirl Banana Cake

Preheat the Oven: Start by preheating your oven to 350 degrees F. Grease a 9×13-inch metal baking pan or line it with parchment paper for easy removal later.
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 mixture aside as you prepare the wet ingredients.
Cream Butter and Sugars: In the bowl of a stand mixer or with a hand mixer, beat together 3/4 cup unsalted butter and 3/4 cup granulated sugar with 3/4 cup packed brown sugar until creamy and smooth. This should take about 3 minutes.
Add Eggs and Banana: Beat in 3 large eggs one at a time, then mix in 2 teaspoons pure vanilla extract. Add in 1 1/2 cups mashed brown bananas and mix until everything is well combined.
Combine Mixtures: With your mixer on low, slowly add the dry ingredients in three parts, alternating with 1 1/3 cups buttermilk. Start and end with the dry mix, taking care not to over mix—just until everything comes together!
Spread Batter: Pour the batter into your prepared baking pan, smoothing it into an even layer. Set aside while you prepare the cinnamon filling.
Make Cinnamon Filling: In a medium bowl, stir together 3/4 cup salted butter, 3/4 cup packed light brown sugar, 1 tablespoon all-purpose flour, and 1 tablespoon ground cinnamon until creamy and smooth.
Swirl Filling: Drop small dollops of the cinnamon filling all over the top of the batter. Then, take the tip of a butter knife and gently swirl it into the top of the batter for that beautiful marbled effect.
Bake: Place the cake in the oven and bake for 30 to 35 minutes. You’ll know it’s ready when a toothpick inserted in the center comes out clean. Keep an eye on it, as every oven is slightly different.
Cool Slightly: Once baked, remove the cake and set the pan on a wire rack to cool for 10 to 15 minutes. Don’t let it cool completely—you’ll want it warm for the glaze!
Prepare the Glaze: While the cake cools, make the glaze. In a stand mixer or using a hand mixer, beat together 2 tablespoons room temperature butter, 4 ounces cream cheese until smooth. Gradually add in 2 cups confectioner’s sugar and 1 teaspoon vanilla extract, mixing well. Add 2 tablespoons milk, beating until smooth. If it’s too thick, add more milk a teaspoon at a time until you achieve your desired consistency.
Glaze the Cake: Spread the glaze over the warm cake, allowing it to gently melt into the top. Cut into squares and serve warm for the best experience.

Storing & Reheating

To keep your Cinnamon Swirl Banana Cake fresh, store it in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate it for up to a week, or freeze it in an airtight container for up to 3 months. When you’re ready to enjoy it again, simply pop it in the microwave for 10-15 seconds to warm it up. Keep in mind that the texture may change slightly once frozen, but a quick warm-up will help refresh its delightful flavor.

Chef’s Helpful Tips

Over-mixing the batter can lead to a denser cake, so mix just until combined.
Ensure all your ingredients, especially eggs and buttermilk, are at room temperature for the best texture.
If using frozen bananas, ensure they’re fully thawed and drained before mashing, as excess moisture can change the cake’s consistency.
For an added crunch, consider folding in some chopped nuts or chocolate chips into the batter.
Want to make this ahead? The glaze can be prepared up to a day in advance; just give it a quick mix before spreading.

Cinnamon Swirl Banana Cake is undeniably a delicious way to use those brown bananas sitting on your countertop! Whether enjoyed as a breakfast treat or an afternoon snack, this cake is soft, sweet, and oh-so-satisfying. I’m excited for you to give this scrumptious recipe a try! Taste the comforting blend of banana and cinnamon in every bite and feel free to experiment with the ingredients. Your kitchen will fill with heavenly aromas, and your loved ones will be eagerly waiting for a slice.

Recipe FAQs

Can I use frozen bananas for this recipe?

Absolutely! Frozen bananas can be a great option. Just let them thaw completely and drain any excess liquid before mashing. They’ll provide that same delicious moisture!

How do I know when the cake is done baking?

The best way to check for doneness is by inserting a toothpick into the center. If it comes out clean or with just a few crumbs, the cake is ready. Remember, every oven is different, so it’s good to check a bit earlier.

Can I make this cake ahead of time?

Yes, you can! The cake keeps well for a few days at room temperature. It also freezes beautifully—just ensure it’s well-wrapped in an airtight container for up to three months. Thaw it in the refrigerator overnight before enjoying.

What can I substitute for buttermilk?

If you don’t have buttermilk, you can make a quick substitute by mixing 1 cup of milk with 1 tablespoon of vinegar or lemon juice. Let it sit for about 5-10 minutes, and you’ll have a perfect buttermilk replacement!

Instructions

Preheat your oven to 350°F (175°C). Grease a 9×13-inch metal baking pan or line it with parchment paper and set aside.
In a large bowl, whisk together flour, baking soda, baking powder, ground cinnamon, and kosher salt. Set aside.
In a stand mixer bowl, cream together unsalted butter, granulated sugar, and brown sugar until smooth, about 3 minutes. Scrape down the bowl as necessary.
Add eggs one by one and mix in the vanilla extract. Fold in the mashed bananas until well combined, scraping the bowl's sides as needed.
Gradually add the dry mixture in three parts, alternating with buttermilk, mixing until just combined without over mixing.
Pour the batter into the prepared pan and prepare the cinnamon swirl filling.
In a medium bowl, mix together softened butter, light brown sugar, flour, and ground cinnamon until creamy.
Drop spoonfuls of the cinnamon filling over the batter and swirl with a butter knife.
Bake for 30 to 35 minutes or until a toothpick inserted in the center comes out clean. Check early, as baking times may vary.
Remove from oven and let cool on a wire rack for 10 to 15 minutes. It’s best served warm when glazing.
For the glaze, beat together the butter and cream cheese in a mixer until smooth. Mix in confectioner's sugar, vanilla, and 2 tablespoons milk; beat for 2 minutes. Add more milk as needed for desired consistency.
Spread the glaze over the warm cake. Cut into squares to serve.
