Creating Pineapple Upside-Down Cake can be a joyful process when you follow these simple steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking dish well.
2. Prepare Pineapple: Drain the pineapple slices, reserving the juice for later use.
3. Make the Topping: In a saucepan over medium heat, melt the butter. Once melted, stir in the brown sugar until well combined.
4. Pour Mixture: Pour the butter-brown sugar mixture evenly into the bottom of the prepared baking dish.
5. Arrange Pineapple: Place the pineapple slices over the butter-brown sugar mixture in a decorative circular pattern.
6. Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, and salt. Set aside.
7. Mix Wet Ingredients: In another bowl, beat the granulated sugar and eggs until light and fluffy. Then, mix in the vanilla and reserved pineapple juice.
8. Combine Ingredients: Gradually add the dry mixture into the wet mixture, alternating with the milk. Mix until just combined and smooth.
9. Pour Batter: Pour the batter over the arranged pineapple in the baking dish. Smooth the top with a spatula.
10. Bake: Place the dish in the preheated oven and bake for about 35-40 minutes or until a toothpick inserted in the center comes out clean.
11. Cool: Remove from the oven and allow the cake to cool in the pan for about 10-15 minutes.
12. Invert and Serve: Carefully invert the cake onto a serving platter, allowing the pineapple and caramel to cascade beautifully over the cake.
