In a large mixing bowl, beat the softened butter and granulated sugar with an electric mixer until light and fluffy. Add eggs one at a time, beating well after each addition. Mix in the vanilla extract.

Blend in the mashed ripe bananas until the batter becomes smooth and well combined.

Add the dry ingredients and buttermilk alternately to the banana mixture, beginning and ending with the dry ingredients. Stir gently just until combined to prevent overmixing.

Divide the batter evenly between the prepared pans, smoothing the surfaces. Bake for 25 to 30 minutes or until a toothpick inserted into the center of each cake comes out clean.

Remove the cakes from the oven and allow them to cool in the pans for 10 minutes. Then transfer to wire racks and let cool completely before applying frosting.

In a bowl, beat softened cream cheese and butter until creamy and smooth. Gradually add powdered sugar on low speed, then incorporate vanilla extract and a pinch of salt. Increase speed to medium-high and mix for 2 to 3 minutes until light and fluffy.

Place one cooled cake layer on a serving plate. Spread a generous layer of frosting on top. Set the second layer over the first and cover the top and sides with the remaining frosting. Decorate as desired.
