Preheat & Prepare the Muffin Tin
Preheat oven to 350°F (175°C). Grease a 12-cup muffin tin with butter or non-stick spray.
Make the Caramelized Topping
In a small bowl, mix melted butter and brown sugar.
Spoon about 1 teaspoon of the mixture into each muffin cup.
Place a half pineapple ring in each cup and press a maraschino cherry in the center.
Make the Cake Batter
In a bowl, whisk together flour, baking powder, baking soda, and salt.
In another bowl, beat butter and sugar until light and fluffy.
Add the egg and vanilla extract, mixing until combined.
Stir in pineapple juice and milk.
Gradually add the dry ingredients, stirring just until combined.
Assemble & Bake
Divide the batter evenly among the muffin cups, filling each about ¾ full.
Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
Let the cakes cool in the pan for 5 minutes, then carefully invert onto a wire rack or plate.
Serve & Enjoy!
Serve warm for the best caramelized flavor! These mini cakes are delicious on their own or with a scoop of vanilla ice cream.
