Ingredients

• 2 cups All-purpose flour
• 1 cup Granulated sugar
• 0.5 cup Brown sugar
• 1 teaspoon Baking powder
• 1 teaspoon Baking soda
• 0.5 teaspoon Salt
• 0.5 cup Unsalted butter, melted
• 0.5 cup Buttermilk
• 3 medium Overripe bananas, mashed
• 2 large Eggs
• 2 teaspoons Vanilla extract
• 2 cups Powdered sugar
• 4 ounces Cream cheese, softened
• 0.25 cup Unsalted butter, softened
• 2 tablespoons Milk
• 1 teaspoon Vanilla extract (for icing)

Directions

Step 1

Preheat your oven to 350°F (175°C). Grease and line a 9x13-inch baking pan with parchment paper.

Step 2

In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, brown sugar, baking powder, baking soda, and salt.

Step 3

In a separate bowl, combine the melted butter, buttermilk, mashed bananas, eggs, and vanilla extract. Mix until smooth.

Step 4

Pour the wet ingredients into the dry ingredients and gently fold until just combined. Do not overmix.

Step 5

Transfer the batter to the prepared pan and spread it evenly. Smooth the surface with a spatula.

Step 6

Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted in the center comes out clean.

Step 7

Remove the cake from the oven and let it cool in the pan for 10 minutes. Then, transfer it to a wire rack to cool completely.

Step 8

While the cake cools, prepare the icing. In a medium bowl, beat the softened cream cheese and butter together using an electric mixer until creamy and smooth.

Step 9

Gradually add the powdered sugar, one cup at a time, mixing well after each addition.

Step 10

Stir in the milk and vanilla extract for icing, and beat until the icing reaches your desired consistency.

Step 11

Once the cake is fully cooled, spread the icing evenly over the top using a spatula.

Step 12

Slice the cake into squares or rectangles and serve. Store leftovers in an airtight container in the refrigerator for up to 3 days.
