Creating Delightful Mini Pineapple Upside Down Cakes is easy and fun! Just follow these steps:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C).
2. Prepare the Pans: Grease 12 muffin cups or ramekins with butter or non-stick spray.
3. Make the Topping: In a small saucepan, melt butter and brown sugar over medium heat until smooth. Pour this mixture into the bottom of each muffin cup.

5. Combine Dry Ingredients: In a bowl, whisk together flour, baking powder, baking soda, and salt.
6. Mix Wet Ingredients: In another bowl, beat the granulated sugar, egg, and vanilla extract. Gradually stir in the buttermilk until well combined.
7. Combine Mixtures: Pour the dry ingredients into the wet mixture, stirring until just combined. Do not overmix.
8. Fill the Pans: Spoon the batter evenly over the pineapples in each cup.
9. Bake: Place in the oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
