In this recipe, ripe bananas play a key role. Their natural sweetness and moisture give the cake its lovely texture. Use bananas that are very ripe. They should be soft and brown for the best results.
Unsalted butter is essential. It adds richness to the cake. Make sure it is softened. This will help it cream well with the sugar.
Granulated sugar sweetens the cake. We use one cup. This helps create a delightful balance with the cinnamon and banana.
Eggs provide structure. They help the cake rise and hold together. Always use large eggs for consistency.
Vanilla extract adds depth. It enhances all the other flavors in the cake. One teaspoon is all you need.
All-purpose flour is the base. It gives the cake stability. Be sure to measure it accurately for the best texture.
Baking powder and baking soda are the leavening agents. They create that light and fluffy cake we all love.
Salt enhances flavor. A little goes a long way. Just half a teaspoon will do.
Ground cinnamon is the star of the show. It adds warmth and spice. Measure out one teaspoon for the batter and a bit more for the swirl.
Sour cream or Greek yogurt adds moisture and tang. Use half a cup in the mix. This makes the cake tender.
Optional Ingredients
Chopped walnuts can add a nice crunch. If you love nuts, toss in half a cup. They bring texture and flavor.
For the cinnamon swirl, brown sugar and extra walnuts are optional. They create a sweet, crunchy topping. Use a quarter cup of brown sugar for the swirl mixture.
These ingredients come together to make a delicious cake. Each one plays a part in the overall flavor and texture. By carefully selecting and measuring them, you set yourself up for baking success!

Step-by-Step Instructions
Preparation Steps
1. Preheat your oven to 350°F (175°C). This helps the cake bake evenly.
2. Prepare a 9-inch round cake pan. Grease it and dust with flour, or line it with parchment paper.
Mixing Ingredients
1. In a big bowl, cream the softened butter and granulated sugar together. Use a hand mixer or stand mixer. Mix until fluffy, about 3 to 5 minutes.
2. Add the mashed bananas, eggs, and vanilla extract to the butter mix. Beat until smooth and combined.
3. In another bowl, whisk together flour, baking powder, baking soda, salt, and ground cinnamon. Make sure everything is mixed well.
4. Gradually fold the dry mix into the wet mix. Alternate with sour cream. Mix gently. Avoid overmixing. If you like, fold in chopped walnuts for extra crunch.
Create the Cinnamon Swirl
1. To make the swirl, mix brown sugar and ground cinnamon in a small bowl. You can add more walnuts if you wish. Blend well.
2. Spoon half of the batter into the prepared pan. Spread it evenly.
3. Sprinkle half of the cinnamon mix over this layer. Pour the rest of the batter on top. Smooth it out gently.
4. Sprinkle the remaining swirl mixture over the top. Use a knife or skewer to swirl it through the batter. This creates a nice pattern.
Baking the Cake
1. Bake your cake in the oven for 45 to 50 minutes. The cake is done when a toothpick inserted in the center comes out clean.
2. After baking, take the cake out of the oven. Let it cool in the pan for about 10 minutes.
3. Carefully transfer the cake to a wire rack to cool completely before slicing.
Tips & Tricks
Best Practices for Success
To get the best texture from your bananas, mash them well. Use a fork or a potato masher. Aim for a smooth paste with no lumps. Ripe bananas work best, as they are sweeter and softer.
Do not overmix the batter. After adding the dry ingredients, mix gently. Stop as soon as you see no flour. Overmixing can lead to a tough cake, which is not what you want.
Presentation Suggestions
For a lovely finish, dust your cake with powdered sugar. This adds a nice touch and looks great. You can also serve it with whipped cream or ice cream. Both pair well and add a creamy contrast to the cake. Enjoy it with a warm cup of coffee.
Common Baking Mistakes
To avoid a dry cake, keep an eye on the baking time. Check for doneness with a toothpick. If it comes out clean, your cake is ready.
Make sure to distribute the cinnamon evenly. When swirling the cinnamon mixture, do it gently. This helps ensure every bite has that sweet cinnamon flavor.
Pro Tips
- Use Ripe Bananas: For the best flavor and moisture, make sure your bananas are very ripe with plenty of brown spots. This enhances the sweetness and banana flavor in your cake.
- Don’t Overmix: When combining the wet and dry ingredients, mix just until combined. Overmixing can lead to a dense cake, so be gentle with your folding.
- Cool Before Slicing: Allow the cake to cool completely on a wire rack before slicing. This helps the cake set and makes for cleaner slices.
- Enhance the Swirl: For a more pronounced cinnamon swirl, use a knife to create deeper swirls in the batter before baking. This will create beautiful layers and enhance the visual appeal.
Variations
Flavor Enhancements
You can make this cake even better by adding chocolate chips. They melt and mix with the bananas, creating a rich flavor. Use about 1/2 cup of semi-sweet chocolate chips for a tasty twist.
Another option is to change the nuts. Try pecans or almonds instead of walnuts. You can also add dried fruits like raisins or cranberries. These additions add a new texture and taste to your cake.
Dietary Modifications
If you need a dairy-free option, use coconut oil instead of butter. Substitute sour cream with almond or coconut yogurt. This keeps the cake moist and delicious.
For a vegan version, replace the eggs with flaxseed meal. Mix 1 tablespoon of flaxseed with 3 tablespoons of water as a substitute. You can also use a plant-based yogurt to keep the texture.
If you want a gluten-free cake, use a gluten-free flour blend. Look for a mix that includes xanthan gum. This helps the cake rise and keeps it fluffy.
Different Cake Formats
You can make this recipe into muffins or mini cakes. For muffins, fill the cups about 2/3 full and bake for 20-25 minutes. Mini cakes will need about 30-35 minutes in the oven.
Adjust the baking time based on the size of your cake. Always check for doneness by inserting a toothpick. It should come out clean when the cake is ready.
Storage Info
Best Practices for Storing Leftovers
To keep your cake fresh, let it cool completely. Place it in an airtight container. This method locks in moisture and flavor. If you don't have a container, cover the cake with plastic wrap. Make sure to press it down to avoid air pockets.
Freezing Instructions
If you want to freeze your cake, slice it first. Wrap each slice in plastic wrap. Then place the slices in a freezer-safe bag. Remove as much air as possible. To thaw, take out a slice and leave it at room temperature. Reheat it in the microwave for about 10 seconds if you prefer it warm.
Shelf Life
This cake stays fresh for about three days at room temperature. If stored properly in the fridge, it can last up to a week. When frozen, it can keep well for about three months. Just make sure to check for any signs of freezer burn before eating.
FAQs
What can I substitute for sour cream in this recipe?
You can use Greek yogurt instead of sour cream. It adds a nice tang. If you want to make homemade sour cream, mix 1 tablespoon of lemon juice with 1/2 cup of milk. Let it sit for about 10 minutes. This will give you a good substitute.
Can I make this cake ahead of time?
Yes, you can make this cake ahead of time. Bake it a day before your event. Let it cool, then store it in an airtight container. This helps the flavors blend. You can also freeze it for longer storage. Just wrap it well in plastic wrap.
How do I know when my cake is done baking?
Look for a golden top and a slight pull from the edges of the pan. The toothpick test is the best way to check. Insert a toothpick in the center. If it comes out clean, your cake is done. If not, bake a few more minutes.
Is this recipe suitable for special occasions?
