Follow these easy steps to create your Easy and Delicious Banana Cake:

1. Preheat oven: Heat your oven to 350°F (175°C) and grease a 9×13-inch baking pan.

2. Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, baking soda, and salt. Set this mixture aside.

3. Cream Butter and Sugar: In another large bowl, cream the softened butter and granulated sugar together until light and fluffy.

4. Add Eggs and Vanilla: Incorporate the eggs, one at a time, mixing well after each addition. Then, stir in the vanilla extract.

5. Combine Mashed Bananas: Add the mashed bananas into the creamed mixture and mix until well combined.

6. Add Dry Mixture and Buttermilk: Gradually fold the dry ingredient mixture into the wet mixture, alternating with the buttermilk, starting and ending with the dry ingredients.

7. Bake the Cake: Pour the batter into the prepared baking pan and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.

8. Cool the Cake: Allow the cake to cool in the pan for about 15 minutes before transferring it to a wire rack to cool completely.
