How to Make Luscious Vanilla Banana Walnut Cake

Preheat Oven: Set your oven to 350°F (175°C) and generously grease two 9-inch round cake pans to prevent sticking.
Mix Dry Ingredients: In a mixing bowl, whisk together the all-purpose flour, baking soda, and salt. This step ensures even mixing, which promotes a fluffy cake texture.
Cream Butter & Sugar: Beat the softened unsalted butter and granulated sugar together until light and fluffy. This should take about 3-4 minutes and will help create air pockets for a lighter cake.
Add Eggs: Incorporate the eggs one at a time into the mixture, ensuring each is fully blended before adding the next. This promotes good emulsification for a smooth batter.
Incorporate Moisture: Gently mix in the sour cream and vanilla extract until fully combined. This combination will add moisture and flavor to your cake.
Fold In Bananas: Carefully fold in the mashed ripe bananas until well integrated. The natural sweetness will enhance the overall taste of your cake.
Combine Mixtures: Gradually add the dry mixture to the wet mixture. Stir together gently until just combined, being careful not to overmix for a light cake texture.
Add Walnuts: Fold in the chopped walnuts to distribute texture throughout the batter. They will provide pleasant crunch in every bite.
Bake: Divide the batter evenly between the prepared pans, smoothing the tops with a spatula. Bake for 35-40 minutes, or until a toothpick inserted comes out clean.
Cool: Once baked, remove the cake pans from the oven and allow them to cool in the pans for about 10 minutes. Carefully level the tops if needed, then transfer to a wire rack to cool completely.
Assemble Cake: Once the layers are cool, place one layer on a serving plate. Spread a generous layer of vanilla custard, then place the second cake on top, drenching it with additional custard.
Garnish: Decorate the top with sliced bananas and whole walnuts for an eye-catching finish before serving.

Optional: Drizzle a bit of extra vanilla custard on each slice for added indulgence!

Luscious Vanilla Banana Walnut Cake Recipe FAQs

What kind of bananas should I use?
Absolutely! You want to use very ripe bananas, ideally with brown spots, as they provide deep sweetness and moisture that elevate your cake’s flavor profile. If you have bananas that are overripe and starting to become mushy, they’re perfect for mashing and using in this recipe.

How should I store the Luscious Vanilla Banana Walnut Cake?
For maximum freshness, store your cake covered with plastic wrap or in an airtight container at room temperature for up to 2 days. If you’d like to keep it longer, refrigerate it for up to 5 days. Just remember to let it come to room temperature before serving for the best texture!

Can I freeze Luscious Vanilla Banana Walnut Cake?
Very much! To freeze, wrap slices individually in plastic wrap and place them in a freezer-safe container. This way, they can keep for up to 3 months. When you’re ready to enjoy, just thaw the slices in the refrigerator overnight. For a quick fix, you can also pop them in the microwave for 10-15 seconds to enjoy warm!

What can I do if my cake is too dense?
If your cake turns out denser than expected, it’s often due to overmixing the batter after combining wet and dry ingredients. Next time, mix just until combined. Also, make sure your baking soda is fresh to ensure proper leavening! And don’t skip incorporating air by creaming the butter and sugar well in the beginning.

Are there any allergy considerations for this recipe?
Absolutely! This cake contains gluten, dairy, and eggs. For a gluten-free version, you can use a gluten-free flour blend. For dairy-free needs, substitute the butter with a dairy-free alternative and replace sour cream with coconut yogurt. Always be mindful of nuts if serving to individuals with nut allergies—feel free to omit the walnuts entirely!

Can I make this cake ahead of time?
Certainly! You can bake the cake layers a day in advance. Store them wrapped in plastic wrap at room temperature. Assemble your Luscious Vanilla Banana Walnut Cake just before serving to keep it fresh and visually appealing! Reheating a slice in the microwave for a few seconds is also a fantastic way to bring back that just-baked warmth.
