Step‑by‑Step Instructions for Heavenly Banana Walnut Cream Cake
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). Prepare two 9-inch round cake pans by greasing them with butter and lightly dusting with flour, or line them with parchment paper for easy removal later. This will help ensure that your Heavenly Banana Walnut Cream Cake comes out intact and ready for layering.
Step 2: Toast the Walnuts
Place 1 cup of chopped walnuts in a dry skillet over medium heat. Toast the walnuts for about 3-4 minutes, stirring frequently, until they become fragrant and lightly golden. Allow them to cool completely before adding to your cake batter, as this enhances their nutty flavor and adds a delightful crunch to your cake.
Step 3: Mix Dry Ingredients
In a large mixing bowl, whisk together 2 cups of all-purpose flour, 2 teaspoons of baking powder, 1 teaspoon of baking soda, and a pinch of salt. Make sure to combine them well and set this mixture aside. This step lays the foundation for a fluffy and well-risen Heavenly Banana Walnut Cream Cake.
Step 4: Cream Butter and Sugar
In another bowl, beat ¾ cup of softened unsalted butter with 1 cup of granulated sugar using an electric mixer on medium speed until the mixture is light and fluffy, about 3-4 minutes. This process incorporates air into the butter, ensuring your cake has a delightful, airy texture. Next, add in 3 large eggs, one at a time, then mix in 1 teaspoon of vanilla extract.
Step 5: Incorporate Bananas and Buttermilk
Add 1 ½ cups of mashed ripe bananas and ½ cup of buttermilk to the butter and sugar mixture. Gently mix until just combined, avoiding overmixing to keep the cake light. The natural moisture of the bananas contributes richly to the cake, making it irresistibly soft and flavorful.
Step 6: Combine Wet and Dry Ingredients
Gradually add the dry mixture to the banana batter, alternating with a bit of the toasted walnuts. Gently fold each addition into the mixture using a spatula until just combined, taking care not to overmix. This helps maintain the lightness essential for the Heavenly Banana Walnut Cream Cake’s texture.
Step 7: Bake the Cake Layers
Divide the batter evenly between the prepared cake pans, smoothing the tops with a spatula. Place them in the preheated oven and bake for 30-35 minutes until the cakes are golden brown and a toothpick inserted in the center comes out clean. Once done, remove them from the oven and allow them to cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
Step 8: Prepare the Banana Filling and Whipped Cream
Meanwhile, toss your sliced banana filling with a splash of lemon juice to prevent browning. In a chilled bowl, whip 1 cup of heavy cream with 2 tablespoons of powdered sugar and an additional teaspoon of vanilla extract until stiff peaks form. This whipped cream will serve as both filling and frosting for a beautiful finish to your Heavenly Banana Walnut Cream Cake.
Step 9: Assemble the Cake
Once the cake layers are completely cool, place one layer on a serving plate. Spread a generous layer of whipped cream on top, followed by a layer of the sliced bananas. Place the second layer of cake on top and frost the top and sides generously with the remaining whipped cream. This creates a stunning visual and adds an utterly delicious touch to each slice.
Step 10: Chill and Serve
To ensure the best texture and flavor, chill the assembled cake in the refrigerator for at least 1 hour before serving. This allows the flavors to meld beautifully and makes for easy slicing. Your Heavenly Banana Walnut Cream Cake is now ready to impress family and friends with its luscious layers and delightful taste!

Make Ahead Options
These Heavenly Banana Walnut Cream Cake layers are perfect for meal prep enthusiasts! You can bake the cake layers up to 24 hours in advance; simply let them cool completely, wrap them tightly in plastic wrap, and store in the refrigerator to maintain freshness. The whipped cream can also be prepped up to 3 days ahead; just store it in an airtight container in the fridge. On the day of serving, layer the banana filling and whipped cream between the cooled cake layers and chill for at least an hour before slicing. This way, you’ll enjoy a moist, delicious dessert with minimal effort, ready to impress anyone at the dinner table!

Heavenly Banana Walnut Cream Cake Recipe FAQs
How do I pick the right bananas for this cake?
Absolutely! For your Heavenly Banana Walnut Cream Cake, aim for bananas that are very ripe, with plenty of dark spots on the skin. Overripe bananas are sweeter and softer, which means they’ll mash easily and provide the maximum flavor and moisture for your cake.
What’s the best way to store the cake?
Store your cake in an airtight container in the fridge for up to 2-3 days. This keeps it fresh and moist. If you need to keep it longer, I recommend wrapping individual slices in cling film and foil, then freeze them for up to 1 month. They make for a perfect indulgent treat when you need a quick dessert!
Can I freeze the Heavenly Banana Walnut Cream Cake?
Yes, you can! To freeze your cake, first wrap it in plastic wrap and then in aluminum foil to prevent freezer burn. It’s best to freeze individual slices, which makes it easier to thaw just what you need. When you’re ready to enjoy, let it thaw in the fridge overnight, then gently heat it in the microwave for about 15-20 seconds to restore its moistness.
What if my cake is too dense?
Very! If your Heavenly Banana Walnut Cream Cake turns out too dense, it might be due to overmixing the batter. It’s crucial to mix just until the ingredients are combined to maintain a light texture. Additionally, ensure your baking powder and baking soda are fresh; expired leavening agents can lead to a cake that doesn’t rise properly.
Are there any substitutions I can use if I have allergies?
Certainly! For a nut-free version, simply replace the toasted walnuts with sunflower seeds or omit them entirely. You can also use gluten-free flour blends if you’re avoiding gluten. If you have dairy allergies, consider using coconut cream in place of heavy cream for the frosting and almond milk plus lemon juice as a substitute for buttermilk. Always check labels to ensure all ingredients are safe for your specific dietary needs.
What’s the best way to prevent the banana filling from browning?
I recommend tossing the sliced bananas with a little lemon juice. This not only keeps them looking fresh but also adds a nice citrus touch to your Heavenly Banana Walnut Cream Cake!
