Key Ingredients & Substitutions
Ripe Bananas: The heart of this recipe! Overripe bananas work best as they’re sweeter and easier to mash. If you don’t have ripe ones, you can bake them at 300°F for 15 minutes until soft.
Butter: Unsalted butter is preferred so you can control the saltiness. If you’re out, coconut oil or vegetable oil can be good alternatives for moisture.
Buttermilk: It adds moisture and a slight tang. No buttermilk? Mix ¼ cup of regular milk with a teaspoon of vinegar or lemon juice and let it sit for a few minutes to thicken up.
Cinnamon: Ground cinnamon is essential for the swirl. If you’re feeling adventurous, mix in a pinch of nutmeg or allspice for extra warmth!
How Do I Achieve the Perfect Cinnamon Swirl?
Creating that lovely cinnamon swirl is simple but needs a gentle touch. Here’s how to do it easily:
- After layering the batter and cinnamon sugar, use a knife to make gentle swirls. Avoid stirring too much; you want the layers to remain visible for that beautiful marbling!
- Don’t worry if the swirl isn’t perfect—that’s part of the charm! Just have fun with it, and remember, the taste will be what matters most!
With these tips, you’ll enjoy a delicious and mouthwatering banana bread that everyone will love. Happy baking!

Easy Homemade Cinnamon Swirl Banana Bread
Ingredients You’ll Need:
For the Banana Bread:
- 1 ¾ cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon salt
- ½ cup unsalted butter, softened
- ½ cup granulated sugar
- ½ cup packed brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 3 ripe bananas, mashed
- ¼ cup buttermilk or plain yogurt
For the Cinnamon Swirl:
- ⅓ cup brown sugar
- 1 tablespoon ground cinnamon
Time Needed:
This delightful banana bread takes about 15 minutes to prepare and 60-70 minutes to bake. After baking, be sure to leave it to cool for about 10 minutes in the pan before transferring it to a wire rack. In total, you’re looking at around 1 hour and 30 minutes to enjoy your sweet treat!
Step-by-Step Instructions:
1. Preheat and Prepare:
Start by preheating your oven to 350°F (175°C). While it heats, grease and flour a 9×5 inch loaf pan to prevent sticking.
2. Mix the Dry Ingredients:
In a medium bowl, whisk together the flour, baking soda, and salt. Set this aside for later because you’ll be adding it to the wet ingredients soon.
3. Cream the Butter and Sugars:
In a large mixing bowl, combine the softened butter, granulated sugar, and brown sugar. Use a mixer to cream them together until the mixture is light and fluffy. This step is crucial for a soft bread!
4. Add Eggs and Vanilla:
Next, beat in the eggs one at a time. After adding the eggs, stir in the vanilla extract to give your bread a sweet aroma.
5. Incorporate Bananas and Buttermilk:
Time to mix in the mashed bananas and buttermilk (or yogurt). Stir just until everything is combined; it’s okay if there are a few lumps from the bananas!
6. Combine Wet and Dry Ingredients:
Gradually fold the flour mixture into the wet mixture. Do this gently to avoid overmixing, which can make the bread dense. It’s all about keeping it light and fluffy!
7. Prepare the Cinnamon Swirl:
In a small bowl, combine the brown sugar and ground cinnamon for the swirl. This mix will create that delightful sweet layer inside your bread.
8. Layer the Batter and Cinnamon Mix:
Pour half of the banana bread batter into your prepared loaf pan. Evenly sprinkle half of the cinnamon sugar mixture over the top.
9. Finish with More Batter and Swirl:
Add the rest of the banana bread batter on top and sprinkle the remaining cinnamon sugar mixture over that. Now, for the fun part—use a knife or skewer to gently swirl the cinnamon into the batter to create a pretty marbled effect!
10. Bake:
Place the loaf pan in the preheated oven and bake for 60-70 minutes. Check your bread by inserting a toothpick in the center; if it comes out clean, your banana bread is ready!
11. Cool & Slice:
Let the bread cool in the pan for about 10 minutes, then carefully transfer it to a wire rack to cool completely. Patience is key; this will help the flavors settle beautifully!
Enjoy your warm, cinnamon-swirled banana bread with a glass of milk or your favorite cup of coffee! It’s the perfect cozy treat for any time of the day.
