To make your Banana Upside Down Cake perfectly, follow these simple steps:

1. Preheat the Oven: Set your oven to 350°F (175°C) and prepare a 9-inch round cake pan.

2. Melt Butter and Sugar: In a saucepan, melt the butter over medium heat. Stir in the brown sugar until it dissolves.

3. Pour Mixture into Pan: Pour the butter-sugar mixture into the base of the cake pan, spreading it evenly.

4. Arrange Bananas: Place the sliced bananas over the melted sugar mixture in an aesthetically pleasing manner.

5. Mix Dry Ingredients: In a bowl, whisk together the all-purpose flour, baking powder, and salt.

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

7. Add Eggs and Vanilla: Mix in the eggs, one at a time, followed by the vanilla extract until the mixture is smooth.

8. Combine Mixtures: Gradually add the dry ingredients, alternating with buttermilk, and mix until everything is incorporated.

9. Pour Batter: Carefully pour the batter over the arranged bananas in the cake pan.

10. Bake: Place the pan in the preheated oven and bake for 40-45 minutes or until a toothpick inserted comes out clean.

11. Cool: Once baked, allow the cake to cool in the pan for about 15-20 minutes.

12. Invert the Cake: Run a knife around the edges, then carefully flip the pan onto a serving plate to reveal the bananas on top.
