Preheat the oven to 350°F (175°C). Grease and flour a 9x13-inch sheet pan.
Prepare dry ingredients: In a medium bowl, whisk together flour, baking soda, baking powder, and salt. Set aside.
Mix wet ingredients: In a large bowl, cream together softened butter and sugar for 2–3 minutes until light and fluffy. Add eggs, one at a time, mixing well after each addition. Stir in mashed bananas and vanilla extract.
Combine wet and dry ingredients: Alternate adding the dry ingredients and buttermilk to the wet mixture, starting with the dry ingredients. Mix until just combined.
Bake: Pour batter into the prepared pan and spread evenly. Bake for 30–35 minutes or until a toothpick comes out clean. Let the cake cool completely.
Make frosting: Beat cream cheese and butter until smooth, then add powdered sugar and vanilla extract. Mix until light and fluffy.
Frost the cake: Once the cake is cool, spread the frosting evenly over the top. Slice into squares and serve.

Use overripe bananas for maximum flavor and moisture.If you don’t have buttermilk, substitute with milk and 1 tablespoon of vinegar or lemon juice.The frosting can be made ahead and refrigerated. Let it come to room temperature before frosting.For a nutty variation, add chopped walnuts or pecans to the batter.
