This banana cake is rich, moist, and bursting with banana flavor. The secret ingredient? Mayonnaise! It adds a tender texture and keeps the cake incredibly soft. With crunchy walnuts and a hint of vanilla, this cake is perfect for breakfast, dessert, or a sweet snack.

Ingredients
- 3 ripe bananas (mashed)
- ½ cup mayonnaise (adds richness and moisture)
- 1 egg (for structure)
- 1 teaspoon vanilla extract (for aroma)
- 2 cups all-purpose flour (base of the cake)
- ¾ cup sugar (for sweetness)
- 1 teaspoon baking powder (for fluffiness)
- ½ teaspoon salt
- ½ cup walnuts (chopped, for crunch)
Preparation Time
- Prep Time: 15 minutes
- Cook Time: 35–40 minutes
- Total Time: 50–55 minutes
Instructions
Step 1: Preheat and Prep
Preheat your oven to 350°F (175°C). Grease and flour a 9-inch cake pan or line it with parchment paper.
Step 2: Mix Wet Ingredients
In a bowl, mash the bananas until smooth. Add mayonnaise, egg, and vanilla extract, then whisk until combined.
Step 3: Mix Dry Ingredients
In a separate bowl, whisk together the flour, sugar, baking powder, and salt.
Step 4: Combine Wet and Dry Ingredients
Gradually fold the dry mixture into the banana mixture. Stir gently until just combined—do not overmix to keep the cake fluffy.
Step 5: Add Walnuts
Fold in the chopped walnuts, reserving a few to sprinkle on top for extra crunch.
Step 6: Bake the Cake
Pour the batter into the prepared cake pan and smooth the top. Bake for 35–40 minutes, or until a toothpick inserted in the center comes out clean.
Step 7: Cool and Serve
Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.
Serving Suggestions
