Making Mini Pineapple Upside Down Cakes is simple if you follow these clear steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 12-cup muffin pan or individual ramekins.
2. Prepare Topping: In a small bowl, mix melted butter and brown sugar until well blended. Pour a small amount into the bottom of each muffin cup.
3. Arrange Pineapple: Place a slice of pineapple in each cup over the sugar mixture. If desired, add a maraschino cherry in the center of each pineapple slice.
4. Mix Dry Ingredients: In a medium bowl, combine flour, granulated sugar, baking powder, baking soda, and salt. Whisk well to blend.
5. Mix Wet Ingredients: In another bowl, whisk together milk, egg, and vanilla extract until smooth.
6. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients while stirring until just combined; avoid over-mixing.
7. Fill Cups: Divide the batter evenly among the muffin cups, pouring over the pineapple and sugar mixture, filling each cup about two-thirds full.
8. Bake: Place the muffin pan in the oven and bake for 15-20 minutes, or until a toothpick inserted into the center comes out clean.
9. Cool: Remove from the oven and let cool for about 10 minutes. To remove the cakes, gently run a knife around the edges and carefully invert them onto a wire rack.
10. Serve Warm: Allow the mini cakes to cool slightly before serving or enjoy them warm for that gooey, caramelized goodness.
