This Cinnamon Swirl Banana Bread is everything homemade banana bread should be: tender, moist, packed with real banana flavor, and crowned with a rich cinnamon-sugar swirl that melts into a caramelized ribbon throughout the loaf.
The top bakes into a crackly, fragrant crust, while the inside stays soft and buttery.
It’s the ultimate comfort bake — perfect for breakfast, afternoon coffee, or a cozy dessert.

How to Make Cinnamon Swirl Banana Bread
1. Prepare the Oven & Pan
Preheat your oven to 350°F (175°C).
Grease a 9×5 loaf pan or line with parchment for easy removal.
2. Mix the Dry Ingredients
In a medium bowl, whisk together:
- flour
- baking soda
- baking powder
- salt
Set aside.
3. Make the Banana Batter
In a large mixing bowl combine:
- mashed bananas
- melted butter
- sugar
- eggs
- vanilla
- sour cream
Mix until smooth.
Fold the dry ingredients into the wet mixture — gently — until just combined.
Do not overmix; this keeps the loaf tender.
4. Prepare the Cinnamon Swirl
In a small bowl, mix:
- sugar
- cinnamon
- melted butter
This creates a thick, fragrant cinnamon paste.
5. Layer the Batter and Swirl
Pour half of the banana batter into the loaf pan.
Spoon half of the cinnamon swirl mixture over the top and drag a knife gently through to create ribbons.
Add remaining batter on top.
Finish with remaining cinnamon swirl, again dragging a knife lightly through the top layer.
If using streusel, sprinkle it evenly over the top.
6. Bake the Loaf
Bake for 55–65 minutes, or until:
- the top is deep golden
- a toothpick inserted into the center comes out clean
If the top begins to brown too quickly, tent lightly with foil halfway through.
7. Cool and Serve
Allow the loaf to cool for at least 20 minutes before slicing.
This helps the swirl set and ensures clean slices.
Serve warm or at room temperature.
