Ingredients You’ll Need

3 cups all-purpose flour: This forms the base of your cake, giving it structure. Use a gluten-free blend for GF options.
1 teaspoon baking soda: Helps the cake rise and provides a nice texture. Don’t skip this!
1 teaspoon baking powder: Works with the baking soda for optimal fluffiness.
3/4 teaspoon ground cinnamon: Adds a warm, aromatic flavor that enhances the bananas.
3/4 teaspoon kosher salt: Balances the sweetness of the sugars.
3/4 cup unsalted butter, at room temperature: Adds richness and moisture. If you prefer, you can use vegetable oil.
3/4 cup granulated sugar: Sweetens the cake without masking the flavor of the bananas.
3/4 cup packed brown sugar: Provides a deeper flavor thanks to its molasses content.
3 large eggs, at room temperature: Essential for binding the cake and adding moisture. Bring eggs to room temperature for the best mixing.
2 teaspoons pure vanilla extract: Enhances all the other flavors beautifully.
1 1/2 cups mashed brown bananas (about 4 medium bananas): The star of the show! Use overripe bananas for maximum sweetness.
1 1/3 cups buttermilk, at room temperature: Keeps the cake moist and tender. Substitute with a milk and vinegar mixture if needed.

3/4 cup packed light brown sugar: For the filling, it brings moisture and a toffee-like flavor.
1 tablespoon all-purpose flour: Helps bind the cinnamon filling together.
1 tablespoon ground cinnamon: Amplifies the flavor of the filling and adds a lovely swirl.
2 tablespoons butter, at room temperature: Gives the glaze a smooth consistency.
4 ounces cream cheese, at room temperature: Makes the glaze rich and creamy; ensures easy spreading.
2 cups confectioner’s sugar: Sweetens the glaze and gives it that lovely silky finish.
1 teaspoon pure vanilla extract: A must for flavoring the glaze.
2 to 3 tablespoons whole milk or heavy cream: Thins out the glaze; adjust to achieve your desired consistency.

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, then set it aside.
Mix the Dry Ingredients: In a large bowl, whisk together 3 cups of all-purpose flour, 1 teaspoon of baking soda, 1 teaspoon of baking powder, 3/4 teaspoon of ground cinnamon, and 3/4 teaspoon of kosher salt. This will ensure a well-mixed, flavorful cake.
Cream 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 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 occasionally.
Add Eggs and Flavor: Beat in the eggs, one at a time, followed by 2 teaspoons of pure vanilla extract. Once combined, stir in 1 1/2 cups of mashed brown bananas until everything is well mixed. Scrape the bowl as necessary to integrate everything smoothly.
Combine Wet and Dry Ingredients: With the mixer on low, gradually add the dry ingredients in three batches, alternating with the 1 1/3 cups of buttermilk. Start and finish with the dry ingredients to keep a unified batter. Avoid overmixing for the best texture.
Prepare the Batter for Baking: Spread the batter into the prepared pan evenly and set it aside while you prepare the cinnamon filling.
Make the Cinnamon Filling: In a medium bowl, stir together 3/4 cup salted butter, 3/4 cup packed light brown sugar, 1 tablespoon of all-purpose flour, and 1 tablespoon of ground cinnamon until creamy and smooth.
Swirl it In: Drop small dollops of the cinnamon filling all over the top of the batter. With the tip of a butter knife, gently swirl the filling into the batter for a marbled effect.
Bake Your Cake: Place the cake in the oven and bake for 30 to 35 minutes. Check it early by inserting a toothpick into the center; it’s done when it comes out clean or with a few moist crumbs attached.
Cool the Cake: Once baked, remove the cake from the oven and place it on a wire rack to cool for 10 to 15 minutes. Allowing it to remain warm before glazing is essential.
Prepare the Glaze: In your stand mixer or using a hand mixer, beat together 2 tablespoons of room temperature butter and 4 ounces of room temperature cream cheese until smooth. Gradually add 2 cups of confectioner’s sugar, 1 teaspoon of vanilla extract, and 2 tablespoons of milk, beating for about 2 minutes. Adjust with additional milk as needed for your desired consistency.
Glaze and Serve: Spread the glaze over the warm cake, allowing it to seep into the crevices. Then, cut into squares and serve warm, or let cool completely if preferred.

Storing & Reheating

This scrumptious cake can be stored at room temperature for up to 2 days. If storing longer, keep it in the fridge in an airtight container for up to a week. You can also freeze the cake for up to 3 months; wrap individual pieces tightly in plastic wrap and then place them in a freezer bag. When you’re ready to enjoy, gently reheat slices in the microwave for about 15-20 seconds, keeping in mind the texture may be a bit different but still delicious!

Chef’s Helpful Tips

Avoid Overmixing: Be gentle when combining wet and dry ingredients to maintain a tender crumb.
Use Ripe Bananas: The riper the bananas, the sweeter and more flavorful your cake will be.
Check Oven Early: Ovens can vary; start checking for doneness at the 30-minute mark.
Glaze Consistency: Modify the thickness of your glaze with milk—thinner for a drizzle, thicker for a more frosting-like finish.
Room Temperature Ingredients: For best results, ensure your eggs, butter, and cream cheese are at room temperature before mixing.

Cinnamon Swirl Banana Cake is truly a delightful addition to any gathering. Not only is it a crowd-pleaser, but it also infuses any occasion with warmth and deliciousness. Feel free to get creative by adding nuts or chocolate chips for a fun twist. Don’t hesitate to experiment with flavors and make it your own. I wholeheartedly invite you to share this joyous cake with your favorite people—it’s sure to become a beloved recipe in your home too!

Recipe FAQs

How can I tell when my cake is done baking?

The easiest way to check for doneness is to insert a toothpick into the center of the cake. It should come out clean or with a few moist crumbs attached. If it comes out wet with batter, your cake needs a bit more time.

Can I use frozen bananas in this recipe?

Yes, absolutely! Just make sure to thaw them beforehand and drain any excess moisture. Frozen bananas are often even sweeter than fresh and will work perfectly in this cake.

What can I substitute for buttermilk?

If you don’t have buttermilk on hand, you can easily make your own! Just mix 1 cup of milk with 1 tablespoon of white vinegar or lemon juice. Let it sit for about 5-10 minutes, and it’s ready to use.

Can I make this cake ahead of time?

Definitely! This cake actually tastes even better the next day as the flavors meld. You can make it a day in advance and store it in the refrigerator. Just remember to bring it to room temperature before serving for the best taste.
