Creating Classic Pineapple Upside-Down Cake is straightforward if you follow these easy steps:

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

2. Prepare Pan: Melt the butter in a 9-inch round baking pan. Swirl it around to coat the bottom evenly.

3. Add Brown Sugar: Sprinkle the brown sugar over the melted butter. Spread it evenly across the bottom of the pan.

4. Arrange Pineapple: Place the drained pineapple slices on top of the brown sugar, arranging them in a circular pattern. Place a maraschino cherry in the center of each pineapple slice.

5. Mix Dry Ingredients: In a bowl, combine the flour, granulated sugar, baking powder, baking soda, and salt.

6. Combine Wet Ingredients: In another bowl, whisk together the milk, vegetable oil, eggs, and vanilla extract until well blended.

7. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring until the batter is smooth and well combined.

8. Pour the Batter: Carefully pour the batter over the arranged pineapple and cherries in the pan, spreading it evenly.

9. Bake: Place the pan in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.

10. Cool: Remove the cake from the oven and let it cool in the pan for about 15 minutes.

11. Invert the Cake: Place a serving plate over the pan and carefully invert it to release the cake onto the plate.

12. Serve: Your Classic Pineapple Upside-Down Cake is now ready to enjoy!
