Preparation Phase & Tools to Use
Before embarking on your baking adventure, ensure your kitchen is ready for action! Start by preheating your oven to 350°F (175°C), a crucial step to ensure even baking. Next, prepare your four 8-inch round cake pans by greasing and flouring them to prevent sticking. This will allow your cakes to release smoothly once baked. It’s helpful to gather all your ingredients together and measure them out beforehand, so you won’t have to scramble looking for something while in the middle of mixing. This cake requires standard baking tools such as mixing bowls, a whisk, and a spatula. Additionally, a toothpick will be handy for testing the cakes for doneness.

Ingredients
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup sour cream
- 3 ripe bananas, mashed
- 1 cup chopped walnuts
- 1/2 cup caramel sauce (plus more for drizzling)
- Additional walnut halves for garnish
Instructions
Step 1: Preheat & Prepare
Begin the baking process by preheating your oven to 350°F (175°C). While it heats, take the time to grease and flour your four 8-inch cake pans. This is essential to ensure that the cakes come out of the pans without any hassle. Proper preparation at this early stage sets you up for success!
Step 2: Mix Dry Ingredients
In a medium-sized mixing bowl, whisk together the all-purpose flour, baking soda, and salt until they are well mixed. This step ensures the leavening agent is evenly distributed throughout the flour, which is key for the cake to rise evenly. Set this mixture aside for now; we’ll be incorporating it shortly.
Step 3: Cream Butter and Sugar
In a large bowl, combine the softened unsalted butter with the granulated sugar. Using an electric mixer, beat them together until the mixture becomes light and fluffy. This process incorporates air into the butter, creating a lighter texture in your cake. Next, add in the eggs one by one, ensuring to beat well after each addition. Stir in the vanilla extract—this will add a lovely flavor to your cake!
Step 4: Combine Ingredients
Now, it’s time to bring it all together. Gradually add the flour mixture into the butter mixture, alternating with the sour cream. Begin and end with the flour mixture to create a balanced texture. Gently stir in the mashed ripe bananas and chopped walnuts until they are evenly distributed throughout the batter. Your batter should now be thick but smooth, with delicious nuggets of walnuts mixed in.
Step 5: Bake the Cakes
Divide the batter evenly among the prepared cake pans, smoothing out the tops with a spatula if needed. Place the pans in the preheated oven, baking for 25-30 minutes. Keep an eye on them and start checking for doneness at the 25-minute mark by inserting a toothpick into the center of a cake. If it comes out clean or with just a few crumbs attached, your cakes are ready!
Step 6: Cool and Assemble
Once baked, remove the cakes from the oven and let them cool in the pans for about 10 minutes. This cooling period helps the cakes release easily from the pans. After the initial cooling, carefully turn them out onto wire racks to cool completely. Once cooled, it’s time for the fun part—assembling the cake! Spread a generous layer of caramel sauce on top of each cake layer as you stack them, ensuring each layer is equally coated. Once stacked, froth the outside of the cake with more caramel sauce and crown it with beautiful walnut halves for garnishing!

Variations
- Protein: Try adding cooked and crumbled bacon for a sweet and savory contrast!
- Vegetables: Incorporate shredded carrots or zucchini for extra moisture and nutrition.
- Spices: Add a teaspoon of cinnamon or nutmeg to enhance the flavor profile and give it a warm, spiced aroma.
Cooking Notes
- Make sure your ingredients are at room temperature for the best texture.
- If you want taller layers, consider using 6-inch pans instead.
- For extra flavor, toast the walnuts before adding them to the batter — this enhances their nutty flavor.
- Wrap any leftover cake tightly in plastic wrap to keep it fresh for a few days!
Serving Suggestions
- Serve it with a scoop of vanilla ice cream on the side for a delightful contrast.
- Pair with a hot cup of coffee or tea for a cozy experience.
Tips
- Overmixing the batter can lead to a dense cake, so mix just until the ingredients are combined.
- Consider using a cake strip around your pans to ensure even baking without domed tops.
- For a chocolate twist, you can substitute half of the all-purpose flour with cocoa powder.
- If you’re making this cake in advance, store it in the fridge for up to three days and bring it to room temperature before serving.
