Making this Banana Upside Down Cake is straightforward. Follow these simple steps to achieve the perfect cake:

1. Preheat your oven to 350°F (175°C). Prepare a 9-inch round cake pan by greasing it with butter.
2. Prepare the Topping: In a small bowl, mix the melted butter and brown sugar. Pour this mixture into the bottom of the prepared pan.
3. Arrange Bananas: Place the sliced bananas evenly on top of the brown sugar mixture.
4. Mix Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
5. Combine Wet Ingredients: In another bowl, mix the granulated sugar, milk, eggs, and vanilla extract with a hand mixer until well combined.
6. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Don’t overmix.
7. Pour Batter: Carefully pour the batter over the bananas in the pan, making sure it spreads evenly.
8. Bake: Place the pan in the preheated oven and bake for 35-40 minutes or until a toothpick inserted in the center comes out clean.
9. Cool: Once baked, remove the cake from the oven and let it cool in the pan for 15-20 minutes.
10. Invert the Cake: Carefully invert the cake onto a serving plate to reveal the beautifully caramelized bananas.
