Ingredients

For the Banana Walnut Cake

• 2 ½ cups all-purpose flour

• 1 teaspoon baking powder

• 1 teaspoon baking soda

• ½ teaspoon salt

• 1 teaspoon ground cinnamon

• ¾ cup unsalted butter, softened

• 1 cup granulated sugar

• ½ cup light brown sugar

• 3 large eggs, room temperature

• 1 cup mashed ripe bananas (about 3 medium bananas)

• ¾ cup sour cream or plain yogurt

• 2 teaspoons vanilla extract

• 1 cup chopped walnuts, lightly toasted

For the Cream Frosting

• 8 oz cream cheese, softened

• ½ cup unsalted butter, softened

• 2 ½ cups powdered sugar, sifted

• 1 teaspoon vanilla extract 

1. Prep the Oven and Pans

Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line them with parchment paper for easy removal.

2. Toast the Walnuts

Spread chopped walnuts on a dry skillet or baking tray and toast for 5–7 minutes, stirring once. This step intensifies flavor and keeps them crunchy inside the cake. Let cool.

3. Mix the Dry Ingredients

In a medium bowl, whisk together flour, baking powder, baking soda, salt, and cinnamon. Set aside.

4. Cream Butter and Sugars

In a large mixing bowl, beat butter with granulated and brown sugar until light and fluffy—about 3 minutes. This step is key to a tender cake.

5. Add Eggs and Bananas

Beat in eggs one at a time, mixing well after each addition. Stir in mashed bananas and vanilla extract until smooth and fragrant.

6. Add Sour Cream and Dry Ingredients

Mix in the sour cream. Gradually add the dry ingredients, mixing just until combined. Do not overmix. Fold in toasted walnuts gently.

7. Bake

Divide batter evenly between prepared pans. Bake for 28–32 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 before frosting.

Cream Frosting Instructions

In a large bowl, beat cream cheese and butter until smooth and creamy. Gradually add powdered sugar, beating on low speed. Add vanilla extract and heavy cream one tablespoon at a time until the frosting is fluffy and spreadable.

The texture should be silky—not stiff, not runny.

Assembling the Cake

Place one cake layer on a serving plate. Spread a generous layer of cream frosting over the top. Add the second cake layer and frost the top and sides. For a rustic look, keep the sides lightly frosted. Garnish with extra chopped walnuts or banana slices if desired.

Pro Tips for Best Results

Storage & Make-Ahead Tips

• Store covered in the refrigerator for up to 4 days
