Vanilla Banana Walnut Cake Ingredients
For the Cake Batter

• Unsalted butter – Creates a rich flavor and adds moisture to your cake.
• Ripe bananas – The star ingredient! Make sure they're well-ripened for maximum sweetness and flavor.
• Large eggs – Use room temperature eggs for better incorporation into the batter.
• Baking powder – Gives your cake that essential rise for a light and fluffy texture.
• Baking soda – Works with the baking powder to enhance the cake's lift.
• Salt – A pinch balances the sweetness and enhances overall flavor.
• Vanilla extract – Amplifies the cake's sweetness and adds a warm aroma.

Step‑by‑Step Instructions for Vanilla Banana Walnut Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) to ensure it's ready for baking. While the oven heats, take this time to grease your chosen cake pan; this will help the Vanilla Banana Walnut Cake to release easily when it's done. A light coating of butter or non-stick spray works well.
Step 2: Cream Butter and Sugar
In a large mixing bowl, combine the softened unsalted butter and granulated sugar. Use an electric mixer on medium speed to cream them together until the mixture is light and fluffy, which should take about 3-4 minutes. This step is essential for creating the light texture of your cake.
Step 3: Mash the Bananas
Next, peel and mash the 3 ripe bananas in a separate bowl until smooth, ensuring there are no large chunks remaining. Once mashed, add these bananas to the creamed butter and sugar mixture, mixing until the ingredients are well combined. The natural sweetness of the bananas will enhance the flavor of your Vanilla Banana Walnut Cake.
Step 4: Add Eggs and Vanilla
Incorporate the two large eggs into your banana mixture one at a time, ensuring each is fully mixed in before adding the next. After both eggs are combined, pour in 1 tablespoon of vanilla extract and mix well. This will create a deliciously fragrant batter, making your kitchen smell divine.
Step 5: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt until evenly mixed. This ensures that the leavening agents are well distributed, contributing to the rise and texture of your Vanilla Banana Walnut Cake. Set this flour mixture aside for the next step.
Step 6: Mix Wet and Dry Ingredients
Gradually add the dry flour mixture to the banana mixture, alternating with the ½ cup of sour cream. Mix gently until just combined; be careful not to overmix as this can lead to a denser cake. This method helps maintain the moistness that sour cream provides while achieving a light texture.
Step 7: Fold in Walnuts and Prepare to Bake
Finally, fold in the 1 cup of chopped walnuts, distributing them evenly through the batter. Then, pour the cake batter into your prepared cake pan, smoothing the top with a spatula. Place the pan in the preheated oven and bake for approximately 50 minutes, or until a toothpick inserted in the center comes out clean.
Step 8: Cool and Serve
Once baked, remove the Vanilla Banana Walnut Cake from the oven and let it cool in the pan for about 10 minutes before transferring it to a wire rack. Allow it to cool completely, then slice and serve. This cake pairs beautifully with a scoop of vanilla ice cream or a warm cup of tea!

Vanilla Banana Walnut Cake Recipe FAQs

What should I do if my cake sinks in the middle?
If your Vanilla Banana Walnut Cake sinks in the middle, it may be due to underbaking or overmixing the batter. Ensure that you're using room temperature ingredients, and always check if your cake is fully baked by testing with a toothpick. A toothpick should come out clean when it’s done. If it’s not baking evenly, you might also check your oven temperature with an oven thermometer—sometimes they can be off!
