Creating your Easy and Delicious Banana Cake is straightforward if you follow these simple steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.
2. Mash Bananas: In a mixing bowl, mash the ripe bananas until smooth. Set aside.
3. Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
4. Add Eggs and Vanilla: Beat in the eggs, one at a time, followed by the vanilla extract. Mix until well combined.
5. Incorporate Bananas: Stir in the mashed bananas until evenly mixed into the batter.
6. Combine Dry Ingredients: In a separate bowl, whisk together the baking soda, salt, and all-purpose flour.
7. Add Dry Ingredients to Wet: Gradually add the dry ingredients to the banana mixture, alternating with the buttermilk. Mix until just combined.
8. Pour the Batter: Pour the batter into the prepared cake pan, smoothing the top for an even layer.
9. Bake: Place the pan in the preheated oven and bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
10. Cool the Cake: Once baked, remove from the oven and let the cake cool in the pan for about 15 minutes. Then transfer it to a wire rack to cool completely.
