Creating Banana Upside Down Cake is a delightful experience. Just follow these steps to achieve a beautiful dessert:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Grease a 9-inch round cake pan for easy removal.
2. Prepare Bananas: Arrange the sliced bananas at the bottom of the prepared pan, ensuring an even layer.
3. Make the Caramel: In a saucepan over medium heat, melt the butter and stir in the brown sugar and cinnamon. Cook until bubbly, then pour evenly over the bananas in the pan.
4. Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
5. Combine Wet Ingredients: In a separate bowl, beat together the granulated sugar and eggs until light and fluffy. Mix in the vanilla extract and buttermilk until well combined.
6. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Avoid over-mixing.
7. Pour Batter: Carefully pour the batter over the banana and caramel layer in the pan, spreading it evenly.
8. Bake: Place the pan in the preheated oven and bake for 35 to 40 minutes, or until a toothpick inserted in the center comes out clean.
9. Cool: Once baked, remove the pan from the oven and allow it to cool for about 10-15 minutes.
10. Invert the Cake: To serve, carefully invert the cake onto a serving plate. The bananas and caramel will be on top, creating a stunning presentation.
