Step-by-Step Instructions
Step 1: Preheat & Prepare Pans
Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together flour, baking soda, and salt. Set aside.
Step 3: Cream Butter & Sugar
In a large mixing bowl, beat softened butter and sugar until light and fluffy. This step incorporates air, giving the cake a tender texture.
Step 4: Add Eggs & Vanilla
Add eggs one at a time, mixing well after each addition. Stir in vanilla extract.
Step 5: Add Bananas & Sour Cream
Mix in mashed bananas and sour cream until smooth and fully combined.
Step 6: Combine Wet & Dry
Gradually add the dry ingredients to the wet mixture. Mix just until combined — avoid overmixing to keep the cake tender.
Step 7: Fold in Walnuts & Chocolate
Gently fold in chopped walnuts and white chocolate chips.
Step 8: Bake
Divide batter evenly between prepared pans. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
Let cakes cool in pans for 10 minutes, then transfer to a wire rack to cool completely.
Step 9: Assemble the Cake
Once cooled:
- Spread half the custard over the first cake layer.
- Place the second layer on top.
- Spread remaining custard over the top (and lightly around the sides if desired).
Step 10: Garnish & Serve
Decorate with banana slices and whole or halved walnuts.
Serve immediately or refrigerate until ready to enjoy.
Expert Tips
- Use very ripe bananas (with brown spots) for maximum flavor and moisture.
- Toast the walnuts lightly for deeper flavor.
- Chill the cake 30–60 minutes before serving for cleaner slices.
- Pat banana slices dry before garnishing to prevent excess moisture.
Storage
Store covered in the refrigerator for up to 3 days.
Because of the custard topping, refrigeration is recommended.
