Follow these easy steps to create a scrumptious Banana Upside Down Cake that will impress your family and friends:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan.
2. Prepare the Banana Topping: Melt the butter in a saucepan over low heat. Stir in the brown sugar until dissolved and bubbly. Pour this mixture into the prepared cake pan.
3. Arrange the Bananas: Slice the ripe bananas into rounds and arrange them on top of the caramel mixture in the pan.
4. Mix the Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
5. Cream the Sugars and Butter: In a large mixing bowl, cream the softened butter and granulated sugar until fluffy. This should take about 2-3 minutes.
6. Add Eggs and Vanilla: Add the eggs one at a time, mixing well after each addition. Then blend in the vanilla extract.
7. Combine with Dry Ingredients: Gradually add the dry ingredients to the creamed mixture, alternating with buttermilk. Stir just until well combined.
8. Pour Batter Over Bananas: Carefully pour the batter over the bananas in the cake pan.
9. Bake: Bake in the preheated oven for 30-35 minutes or until a toothpick inserted into the center comes out clean.
10. Cool Slightly: After removing from the oven, let the cake cool in the pan for about 15 minutes.
11. Invert the Cake: Place a serving plate on top of the cake pan and flip it over to release the cake. Carefully remove the pan, allowing the bananas to cascade beautifully onto the surface.
