Step‑by‑Step Instructions for Luscious Vanilla Banana Walnut Cake
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it warms up, take two 9-inch round cake pans and generously grease them with butter or cooking spray and then lightly dust with flour to prevent sticking. This initial step ensures your Luscious Vanilla Banana Walnut Cake will smoothly release from the pans after baking.
Step 2: Mix Dry Ingredients
In a medium bowl, combine 2 cups of all-purpose flour, 1 teaspoon of baking soda, and ½ teaspoon of salt. Whisk together until uniform, ensuring there are no lumps. This dry mixture will provide the structure for your cake. Set it aside, allowing the leavening agent to be ready when you combine it with the wet ingredients.
Step 3: Cream Butter and Sugar
In a large mixing bowl, beat ¾ cup of softened unsalted butter with 1 cup of granulated sugar using a hand mixer or stand mixer on medium speed. Continue mixing for about 3-5 minutes, until the mixture is light and fluffy. This process incorporates air into your batter, resulting in a beautifully tender Luscious Vanilla Banana Walnut Cake.
Step 4: Add Eggs
Crack in 2 large eggs one at a time, mixing well after each addition. Beat until fully incorporated, which should take about 1 minute per egg. This is crucial for achieving that smooth batter texture. Remember, adding the eggs gradually helps to ensure an even mixture and strengthens the cake’s structure.
Step 5: Incorporate Wet Ingredients
Next, add ½ cup of sour cream and 2 teaspoons of pure vanilla extract into your batter. Mix on low speed until just blended, about 30 seconds. The sour cream adds moisture and richness, enhancing the flavor of the Luscious Vanilla Banana Walnut Cake while the vanilla amplifies the overall aroma.
Step 6: Blend in Bananas
Mash 3 ripe bananas in a separate bowl until smooth, then fold them gently into the wet mixture. Stir until the bananas are fully incorporated, which should take about a minute. The bananas not only infuse natural sweetness but also contribute to the moist texture of the cake, making each bite irresistible.
Step 7: Combine Dry Ingredients
Gradually add the dry flour mixture to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix; stopping once you see dry flour will help maintain a light and airy cake. The secret to a perfect Luscious Vanilla Banana Walnut Cake lies in this gentle folding technique.
Step 8: Add Walnuts
Once combined, fold in 1 cup of chopped walnuts with a spatula, ensuring they are evenly distributed throughout the batter. The walnuts add a delightful crunch to each slice, beautifully enhancing the flavors of the Luscious Vanilla Banana Walnut Cake.
Step 9: Bake the Cake
Divide the batter evenly between the prepared cake pans and smooth the tops with a spatula. Bake in your preheated oven for 35-40 minutes. Check for doneness by inserting a toothpick in the center; it should come out clean. Your cake will rise beautifully, filling your kitchen with a comforting aroma.
Step 10: Cool the Cakes
Once baked, remove the pans from the oven and let them cool in the pans for about 10 minutes. Carefully invert the cakes onto wire racks to cool completely. This cooling step is vital for successfully assembling your Luscious Vanilla Banana Walnut Cake without compromising its structure.
Step 11: Assemble the Cake
Once cool, place one layer of cake on a serving plate. Spread a generous layer of vanilla custard filling between the two cake layers. Top with the second cake layer and drizzle remaining custard over the top, allowing it to cascade deliciously down the sides, creating an inviting presentation.
Step 12: Garnish and Serve
Lastly, decorate your cake with sliced bananas and additional chopped walnuts on top, if desired. Brush the banana slices with lemon juice to prevent browning. This finishing touch makes your Luscious Vanilla Banana Walnut Cake as beautiful as it is delightful, ready to serve at gatherings or simply for a special treat.

Storage Tips for Luscious Vanilla Banana Walnut Cake
Fridge: Store your cake in an airtight container in the refrigerator for up to 5 days to keep it moist and fresh.
Freezer: For longer storage, wrap individual slices tightly in plastic wrap and place them in a freezer-safe bag. It can last up to 3 months in the freezer.
Reheating: When you’re ready to enjoy a slice, simply reheat it in the microwave for about 15-20 seconds for a warm treat.
Room Temperature: If you’re serving the cake the same day, it’s fine to keep it at room temperature for up to 2 days; just cover it to maintain moisture.
Make Ahead Options
These Luscious Vanilla Banana Walnut Cakes are perfect for meal prep enthusiasts! You can prepare the cake layers up to 3 days in advance by baking and letting them cool completely, then tightly wrapping them in plastic wrap and refrigerating to maintain their moisture. The vanilla custard filling can also be made 24 hours ahead; store it in an airtight container in the refrigerator. When you’re ready to serve, simply layer the custard between the chilled cake layers and drizzle the remaining custard on top. Garnish with sliced bananas and walnuts just before serving to ensure they stay fresh and vibrant.
