Making Banana Upside Down Cake is an enjoyable process. Follow these simple steps to achieve a stunning result:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).

2. Prepare the Cake Pan: Grease a 9-inch round cake pan with butter or cooking spray and set it aside.

3. Prepare Bananas: Slice the ripe bananas into rounds and set aside.

4. Make the Topping: Melt the butter in a saucepan over medium heat. Add the brown sugar and stir until dissolved. Remove from heat and pour the mixture into the bottom of the prepared cake pan.

5. Arrange the Bananas: Place the banana slices over the brown sugar mixture in a single layer, covering the bottom of the pan evenly.

6. Mix Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.

7. Mix Wet Ingredients: In another bowl, beat the granulated sugar and eggs until pale and fluffy. Then add the vanilla extract and buttermilk, mixing well.

8. Combine Mixtures: Gradually add the dry mixture to the wet ingredients, stirring until just combined. Be careful not to overmix.

9. Pour Batter: Carefully pour the batter over the arranged bananas in the cake pan, spreading it evenly.

10. Bake: Place the cake in the preheated oven and bake for 45-50 minutes or until a toothpick inserted in the center comes out clean.

11. Cool: Once done, remove the cake from the oven and let it cool in the pan for about 10-15 minutes.

12. Invert the Cake: Carefully place a serving plate over the top of the cake pan. With oven mitts, flip it over to invert the cake onto the plate, allowing the bananas to be showcased beautifully on top.

13. Let It Rest: Allow the cake to cool slightly before serving.
