Creating your Pineapple Upside-Down Cake can be a joyful endeavor if you follow these steps:

1. Preheat: Begin by preheating your oven to 350°F (175°C).
2. Prepare the Pan: Melt the butter and pour it into a 9-inch round cake pan. Ensure the butter coats the bottom evenly. Sprinkle brown sugar over the melted butter.
3. Arrange Pineapple: Lay the pineapple slices over the brown sugar layer. If desired, place maraschino cherries in the center of each pineapple ring for added color and flavor.
4. Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, and salt. Set aside.
5. Mix Wet Ingredients: In a large bowl, combine granulated sugar, eggs, milk, reserved pineapple juice, and vanilla extract. Beat until well combined.
6. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, stirring gently to avoid lumps. Mix until fully incorporated and smooth.
7. Pour Batter: Gently pour the batter over the arranged pineapples in the pan, spreading it evenly.
8. Bake: Place the cake in the preheated oven and bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean.
9. Cool: Remove the cake from the oven and let it cool in the pan for about 10-15 minutes.
10. Invert: Carefully flip the cake onto a large plate or cake stand, allowing the pineapples to sit on top.
