This cinnamon swirl banana bread transforms ordinary overripe bananas into a decadent treat that fills your home with an irresistible aroma. The warm swirls of cinnamon dance through each slice creating a beautiful marbled effect that tastes as impressive as it looks.
I created this recipe during a rainy weekend when my countertop was overflowing with spotted bananas. What started as a way to reduce food waste quickly became my most requested bake sale contribution and holiday gift for neighbors.
Ingredients
- Ripe bananas the spottier the better as they provide natural sweetness and moisture
- Unsalted butter adds richness and helps create that tender crumb
- Granulated sugar balances the banana flavor without overpowering
- Large egg provides structure and binds everything together
- Vanilla extract enhances the banana flavor with warm undertones
- All purpose flour creates the perfect texture not too dense or too light
- Baking soda ensures proper rise without a chemical aftertaste
- Salt essential for balancing sweetness and enhancing flavors
- Ground cinnamon the star of the swirl adds warmth and complexity
- Brown sugar creates caramelization in the cinnamon swirl pockets
Step-by-Step Instructions
- Prep Your Equipment
- Preheat your oven to exactly 350°F allowing at least 15 minutes for it to reach temperature. Thoroughly grease your loaf pan ensuring you get into all corners to prevent sticking. I prefer using butter for greasing as it adds a subtle flavor boost.
- Mix Wet Ingredients
- In a large bowl combine your mashed bananas with melted butter using a fork or potato masher to eliminate all lumps. Add granulated sugar and stir until it begins dissolving into the mixture. Beat in the egg and vanilla extract until the mixture looks smooth and uniform.
- Combine Dry Ingredients
- Whisk flour baking soda and salt in a separate bowl ensuring even distribution of leavening agents. Slowly add this dry mixture to your wet ingredients folding gently with a spatula. Stop mixing as soon as no dry flour is visible overmixing will create a tough bread.
- Create Cinnamon Swirl
- In a small bowl thoroughly combine the ground cinnamon and brown sugar breaking up any clumps with your fingertips. The mixture should look like damp sand when properly mixed. This ensures even distribution of cinnamon flavor throughout the swirl.
- Layer and Swirl
- Pour exactly half of your batter into the prepared pan smoothing it into an even layer. Sprinkle half the cinnamon mixture evenly across the surface then add remaining batter on top. Finish with the remaining cinnamon sugar. Using a butter knife insert deeply and create figure eight motions to create marbling without overmixing.
- Bake to Perfection
- Place the loaf in the center rack of your preheated oven and bake for 60 to 70 minutes. After 45 minutes check for excessive browning and tent with foil if needed. The bread is done when a toothpick inserted in the center comes out with a few moist crumbs but no wet batter.

The cinnamon swirl is what truly elevates this banana bread from everyday to extraordinary. My grandmother taught me this technique when I was just eight years old and watching the transformation of simple ingredients into something so beautiful was what sparked my love of baking. The smell of this bread baking still takes me back to her kitchen.
Ripeness Matters
The ripeness of your bananas dramatically affects the final product. For this recipe aim for bananas that are heavily spotted or even completely black. These overripe bananas contain more sugar which creates a moister sweeter bread with intense banana flavor. If your bananas arent quite ready place them in a paper bag with an apple for a day to speed up ripening.
Make It Your Own
This recipe serves as a wonderful base for customization. Add half a cup of chopped walnuts or pecans for delightful crunch. Chocolate chips blend beautifully with the cinnamon swirl creating pockets of melty goodness. For a tropical twist fold in half a cup of shredded coconut. You can even substitute quarter cup of the all purpose flour with whole wheat for added nutrition without sacrificing texture.
Proper Storage
Store your banana bread at room temperature wrapped in plastic wrap or in an airtight container for up to three days. The flavor actually improves overnight as the cinnamon has time to permeate throughout the loaf. For longer storage slice the completely cooled bread wrap individual portions in plastic wrap then place in a freezer bag. Frozen slices can be thawed at room temperature or gently warmed in the microwave for a quick treat.
Serving Suggestions
While delicious on its own this cinnamon swirl banana bread reaches new heights when served warm with a pat of salted butter that slowly melts into each slice. For brunch pair with fresh fruit and coffee. Transform it into a decadent dessert by toasting a slice and topping with vanilla ice cream and a drizzle of caramel sauce. Leftover slices make exceptional french toast dipped in egg mixture and pan fried until golden.
Recipe FAQs
- → How do I know when my bananas are ripe enough for this bread?
The best bananas for this bread are very ripe with plenty of brown spots or even mostly black peels. These overripe bananas are sweeter, softer, and provide more robust banana flavor to your bread.
- → Can I freeze this banana bread?
Yes! This bread freezes beautifully. Allow it to cool completely, then wrap tightly in plastic wrap and aluminum foil or place in a freezer bag. It will keep for up to 3 months. Thaw at room temperature before serving.
- → Why did my cinnamon swirl sink to the bottom?
If your cinnamon swirl sinks, your batter might be too thin. Make sure you're using the correct amount of flour, and try tossing the cinnamon-sugar mixture with a tiny bit of flour before sprinkling it into the batter to help it stay suspended.
- → How do I achieve the perfect swirl pattern?
For the best swirl pattern, use a knife or skewer to make just a few figure-eight motions through the batter. Don't over-swirl or you'll lose the distinct layers. Aim for 5-6 gentle passes through the mixture.
- → Can I add nuts or chocolate chips to this bread?
Absolutely! Chopped walnuts, pecans, or chocolate chips make excellent additions. Fold about 1/2 cup of any of these into the batter just before pouring it into the pan for extra texture and flavor.
- → How can I tell when the bread is done baking?
Insert a toothpick into the center of the loaf - it should come out clean or with a few moist crumbs (but no wet batter). The top should be golden brown, and the bread may start to pull away slightly from the sides of the pan.
