Vanilla Banana Walnut Cake Ingredients

- 3 ripe bananas – The star ingredient, providing natural sweetness and flavor; the riper, the better!
- 2 large eggs – Binds the ingredients together while adding a light, fluffy texture.
- 1 ½ teaspoons baking powder – Ensures your cake rises perfectly, giving it that delightful softness.
- ½ teaspoon baking soda – Helps the cake rise and adds a touch of browning to the crust.
- ½ teaspoon salt – Enhances all the flavors in this scrumptious cake.

Step‑by‑Step Instructions for Luscious Vanilla Banana Walnut Cake
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) and prepare a 9x5 inch loaf pan by greasing it with butter or non-stick spray. This ensures that your Luscious Vanilla Banana Walnut Cake comes out effortlessly after baking. While the oven heats, gather your ingredients together on the countertop for easy access.
Step 2: Cream the 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 takes about 3-5 minutes. This process incorporates air and sets the foundation for a light cake texture.
Step 3: Incorporate the Bananas
Next, add the three ripe bananas to the creamed butter and sugar. Using a fork or a potato masher, mash the bananas thoroughly into the mixture until well combined. The mashed bananas will bring incredible moisture and sweetness to your Luscious Vanilla Banana Walnut Cake.
Step 4: Mix in the Eggs and Vanilla
Crack the two eggs into the banana mixture, followed by one tablespoon of vanilla extract. Beat the mixture on low speed until fully incorporated—about 1-2 minutes—making sure everything is well-combined. This step adds richness and depth of flavor to your cake.
Step 5: Combine the Dry Ingredients
In a separate bowl, sift together the all-purpose flour, baking powder, baking soda, and salt. This aerates the flour and helps ensure no lumps remain. Gradually add this dry mixture to the banana mixture in your large bowl, mixing gently to combine; be careful not to overmix, which can toughen your cake.
Step 6: Add the Sour Cream
Alternately incorporate the sour cream into the batter, adding a spoonful at a time while mixing gently. Continue until the sour cream is just combined with the batter; this ingredient adds richness and keeps the cake moist. It's important not to overwork the batter, so mix just until you see no dry flour.
Step 7: Fold in the Walnuts
Gently fold in the one cup of chopped walnuts using a spatula. This will add a lovely crunch to your Luscious Vanilla Banana Walnut Cake. Once evenly distributed, pour the batter into the prepared loaf pan, smoothing the top gently to ensure even baking.
Step 8: Bake to Perfection
Place the loaf pan in the preheated oven and bake the cake for 50-60 minutes. Keep an eye on it; it’s ready when a toothpick inserted in the center comes out clean or with just a few moist crumbs. The golden top and delightful aroma will signal when your cake is done!
Step 9: Cool and Serve
Once baked, carefully remove the loaf pan from the oven and let it cool in the pan for about 10-15 minutes. After that, transfer the cake to a wire rack to cool completely. Slice and serve your warm Luscious Vanilla Banana Walnut Cake, enjoying the delightful flavors and comforting texture!

Tips for the Best Vanilla Banana Walnut Cake
-
Use Ripe Bananas: The riper your bananas, the sweeter and moister your cake will be. Look for bananas with brown spots for the best flavor.
-
Don’t Overmix: When combining the dry ingredients with the wet, mix just until incorporated. Overmixing can result in a tough texture, ruining your Luscious Vanilla Banana Walnut Cake.
-
Egg Temperature Matters: Make sure your eggs are at room temperature for optimal blending. This helps the batter combine smoothly for a lighter cake.
-
Check for Doneness: Use a toothpick to check if your cake is ready—aim for a clean or slightly moist crumb. Less is more; don’t let it dry out!

Cool Properly: Allow the cake to cool in the pan initially before transferring it to a wire rack. This avoids breaking and ensures a nice shape when serving.
