DIRECTIONS:

1. Preheat Oven & Prepare Pan:
Preheat your oven to 350°F (175°C).
Grease and lightly flour a 9×13-inch baking pan.
2. Make the Cake Batter:
In a medium bowl, whisk together the flour, baking soda, and salt.
In a large bowl, cream the softened butter with granulated and brown sugar until light and fluffy.
Add eggs one at a time, beating well after each addition, followed by the vanilla extract.
Gradually mix in the mashed bananas.
Alternate adding the flour mixture and buttermilk to the banana mixture, starting and ending with the dry ingredients. Mix until just combined.
3. Bake the Cake:
Pour the batter into the prepared baking pan and smooth the top.
Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean.
Let the cake cool completely in the pan before frosting.
