Moist Cinnamon Swirl Banana Bread

This Cinnamon Swirl Banana Bread elevates classic banana bread into something a little more decadent. It stays wonderfully moist thanks to melted butter, ripe bananas, and a bit of yogurt, while a ribbon of buttery cinnamon sugar runs through the loaf for a gooey, spiced center. The top is brushed with melted butter and a sprinkle of sugar for a lightly crunchy, caramelized crust. The result tastes like the best part of a cinnamon roll folded into a tender banana loaf.

If you usually add chocolate to banana bread, try this cinnamon swirl instead — the warm spice and sticky sweet ribbon change the whole experience. The texture is soft and tender, the flavor is warmly spiced, and the finishing crunch makes each bite irresistible.

Recipe highlights

• Moist and tender: Very ripe bananas, melted butter, and yogurt keep the crumb soft and rich.
• Cinnamon swirl: Layers of cinnamon sugar create a gooey, spiced ribbon and a marbled interior.
• Butter-brushed finish: Brushing the warm loaf with butter and sugar yields a slightly crunchy, flavored crust.
• No mixer required: The recipe comes together in a few bowls with simple whisking and folding.

How to make cinnamon swirl banana bread

Below is a clear, step-by-step overview of the process. Full measurements and the full ingredient list appear in the recipe card at the bottom of this post.

1. Whisk the wet ingredients: Mash very ripe bananas and whisk with melted butter, sugar, eggs, yogurt, and vanilla until smooth and combined.
2. Combine the dry ingredients: In a separate bowl, whisk together the flour, baking soda, and salt.
3. Fold together: Gently fold the dry ingredients into the wet until the mixture is just combined. Avoid over-mixing to keep the loaf tender.
4. Layer batter and cinnamon sugar: Pour roughly one third of the batter into the prepared loaf pan, sprinkle a third of the cinnamon sugar mixture over it, repeat once more, then top with the remaining batter. Reserve some cinnamon sugar for the topping.
5. Bake: Bake until the top is golden and the loaf springs back lightly to the touch.
6. Brush and finish: When the loaf is warm, brush the top with melted butter and press the remaining cinnamon sugar onto the crust for extra crunch and caramelized flavor.

5. Bake: Bake until golden and set in the center, then allow a short rest before removing from the pan.

6. Brush and coat: Brush the warm loaf with melted butter and sprinkle with the reserved cinnamon sugar to create a sweet, slightly crunchy finish.

Variations

Add nuts: Fold in chopped walnuts or pecans for a pleasant crunch and extra depth alongside the cinnamon.

Chocolate twist: Stir a handful of mini chocolate chips into the batter for a richer, sweeter version.

Brown the butter: For a nutty, caramel-like flavor, brown the butter before mixing it with the wet ingredients. This adds complexity without changing technique.

Spice it up: Mix a pinch of nutmeg, ground ginger, or pumpkin pie spice into the cinnamon sugar for additional warmth and spice complexity.

Storage

Store the loaf at room temperature, wrapped tightly, for up to 4 days. The cinnamon swirl often tastes better after a day, as the flavors meld and the center becomes gooier.

To freeze, slice and wrap individual portions tightly in plastic and place in an airtight container. Thaw at room temperature or warm briefly in a low oven or microwave.
