Step‑by‑Step Instructions for Vanilla Banana Walnut Cake
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C), filling your kitchen with that warm, inviting energy. While it heats up, take a 9x5 inch loaf pan and grease it thoroughly with butter or non-stick spray to ensure your Vanilla Banana Walnut Cake releases easily after baking.
Step 2: Cream Butter and Sugar
In a mixing bowl, combine ½ cup softened unsalted butter with 1 cup granulated sugar. Use an electric mixer to beat them together until the mixture is light and fluffy, about 3-4 minutes. This step is essential for infusing your cake with a rich, sweet flavor and a delightful texture that will make every bite heavenly.
Step 3: Add Wet Ingredients
Next, incorporate the star ingredients of your Vanilla Banana Walnut Cake: add 3 ripe, mashed bananas, 2 large eggs, and 1 tablespoon of vanilla extract into the bowl. Mix everything together on medium speed until it’s smooth and well combined. The batter should look creamy, with no lumps from the bananas to ensure a moist cake.
Step 4: Mix Dry Ingredients
In a separate bowl, whisk together 2 cups of all-purpose flour, 1 ½ teaspoons baking powder, ½ teaspoon baking soda, and ½ teaspoon salt. This step helps to evenly distribute the leavening agents for a consistent rise. The flour mixture should look fluffy and airy, ensuring your cake will be light and fluffy when baked.
Step 5: Combine Wet and Dry Mixtures
Gradually add the dry ingredients to the wet mixture. Alternate this addition with ½ cup sour cream, mixing on low speed just until everything is incorporated. Be careful not to overmix; you want a few streaks of flour remaining. The batter will be thick and moist, setting you up for a fantastically textured Vanilla Banana Walnut Cake!
Step 6: Fold in Walnuts
Gently fold in 1 cup of chopped walnuts using a spatula, ensuring they are evenly distributed without overworking the batter. This step adds delightful crunch to your cake, allowing each slice to surprise with a nutty texture. The aroma of bananas and vanilla mixed with the walnuts will make your kitchen smell amazing!
Step 7: Bake the Cake
Pour the batter into the prepared loaf pan, smoothing the top with a spatula. Place it in your preheated oven and bake for 50-60 minutes. Your cake is done when a toothpick inserted into the center comes out clean and the top is golden brown. Keep an eye on the last few minutes to achieve perfection without overbaking.
Step 8: Cool and Serve
Once baked, remove your Vanilla Banana Walnut Cake from the oven and let it cool in the pan for about 10 minutes. Then, transfer it onto a wire rack to cool completely. This cooling process is vital for slicing, as it helps maintain the integrity of the cake, allowing for beautiful, moist slices that your loved ones will adore!

Vanilla Banana Walnut Cake Recipe FAQs
How do I select the best bananas for this cake?
Absolutely! Look for very ripe bananas that have plenty of brown spots on their skin. The more ripe the bananas, the sweeter and moister your Vanilla Banana Walnut Cake will be. This natural sweetness is what makes the cake truly delightful!
What is the best way to store leftover cake?
For optimal freshness, store your Vanilla Banana Walnut Cake in an airtight container at room temperature for up to 3 days. If you need it to last longer, simply wrap it tightly in plastic wrap and then place it in a covered container in the fridge for up to a week.
Can I freeze the cake, and if so, how?
Of course! For freezing, slice your Vanilla Banana Walnut Cake and wrap each slice individually in plastic wrap. Then, wrap them in aluminum foil and freeze for up to 3 months. This method helps maintain its moisture and flavor. When you're ready to enjoy, thaw the slices overnight in the fridge or microwave them for about 15-20 seconds!
What should I do if my cake doesn’t rise properly?
If your cake doesn’t rise, check that your baking powder and baking soda are fresh; if they’re expired, they won’t provide the necessary lift. Also, ensure you didn’t overmix the batter after adding flour, as this can lead to a denser cake. Always insert a toothpick into the center to check for doneness; it should come out clean when your cake is ready.
Is this cake suitable for those with nut allergies?
Not at all! If you have a nut allergy or are baking for someone who does, feel free to leave out the walnuts entirely. You can substitute them with pumpkin seeds or simply make the cake without any mix-ins; it will still be delicious and moist thanks to the bananas!
How long does the cake keep its flavor and moisture?
When stored properly, your Vanilla Banana Walnut Cake will retain its great taste and moist texture for about a week in the fridge. For best results, always store it covered to prevent it from drying out. Enjoy it fresh for a delightful treat at any time!
