Ingredients for Banana Cake with Peanut Butter Frosting

Here’s everything you’ll need to make this Banana Cake with Peanut Butter Frosting

• 3 ripe bananas, mashed
• 2 cups all purpose flour
• 1 teaspoon baking soda
• ½ teaspoon salt
• ¾ cup granulated sugar
• ½ cup brown sugar
• ½ cup unsalted butter, melted and cooled
• 2 large eggs
• 1 teaspoon vanilla extract
• ½ cup milk or buttermilk

For the Peanut Butter Frosting

• ½ cup creamy peanut butter
• ½ cup unsalted butter, softened
• 2 cups powdered sugar
• 2–3 tablespoons milk
• 1 teaspoon vanilla extract

How to Make Banana Cake with Peanut Butter Frosting

Step One

Preheat your oven to 175°C (350°F). Grease or line a 23x33cm (9×13 inch) baking pan to prevent sticking.

Step Two

In a medium bowl, whisk together the flour, baking soda, and salt. Set aside. In a large bowl, beat together the white sugar, brown sugar, melted butter, eggs, and vanilla extract until smooth. The mixture should be glossy and creamy.

Step Three

Add the mashed banana to the wet ingredients and stir until well combined. The banana should blend smoothly and give the mixture a creamy consistency. Gradually add the dry ingredients to the wet ingredients, stirring continuously. Pour in the milk and stir gently until the batter is smooth, but avoid overmixing to keep the cake moist.

Step Four

Pour the batter into the prepared pan and spread it evenly with a spatula. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.

Step Five

Remove the cake from the oven and let it cool completely in the pan. This is important because a warm cake can melt the frosting. While the cake is cooling, prepare the frosting by beating the peanut butter and softened butter together until creamy. Add the powdered sugar, milk, and vanilla, then beat until smooth and light. Spread the frosting evenly over the cooled cake, then slice and enjoy!
