Making Pineapple Upside-Down Cake is relatively simple when you follow these clear steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). You’ll want it nice and hot for that perfect cake rise.

2. Prepare the Pan: Melt the butter in a 9-inch round cake pan. Swirl the pan to coat the bottom evenly. Sprinkle brown sugar over the melted butter, covering the entire base.

3. Arrange Pineapples: Next, place the drained pineapple slices on top of the brown sugar mixture. You can add maraschino cherries to fill the center of each pineapple slice if desired.

4. Mix Dry Ingredients: In a mixing bowl, combine flour, granulated sugar, baking powder, baking soda, and salt. Whisk together until well blended.

5. Combine Wet Ingredients: In a separate bowl, beat the eggs and mix them with the milk and vanilla extract.

6. Combine Mixtures: Gradually add the wet mixture to the dry mixture. Stir until combined, ensuring no lumps remain.

7. Pour Batter: Carefully pour the batter over the arranged pineapples in the cake pan, making sure it covers them evenly.

8. Bake: Place the cake pan in the preheated oven and bake for 40-50 minutes. A toothpick inserted in the center should come out clean when it’s ready.

9. Cool the Cake: Once baked, remove the cake from the oven and let it cool in the pan for about 15-20 minutes.

10. Invert and Serve: After cooling, carefully flip the cake onto a serving plate. The pineapple and caramelized sugar topping will now be visible.
