Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

In a mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.

Add the eggs one at a time, mixing well after each addition. Stir in the mashed bananas and vanilla extract.

In another bowl, whisk together the flour, baking soda, and salt.

Gradually add the dry ingredients to the banana mixture, alternating with the buttermilk. Mix until just combined.

Divide the batter evenly between the prepared cake pans.

Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.

Allow the cakes to cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely.

In a mixing bowl, beat the softened cream cheese and butter together until smooth.

Gradually add the powdered sugar and vanilla extract, mixing until the frosting is light and fluffy.

Once the cakes are completely cool, place one layer on a serving plate and spread a layer of cream cheese frosting on top.

Place the second layer on top and frost the top and sides of the cake with the remaining cream cheese frosting.

Slice and serve the cake. Enjoy!
