Preheat the oven to 350°F.
Coat 24 regular-sized muffin cups with cooking spray.(or a dozen greater)
Cut each pineapple slice into four pieces and leave aside.
In a large mixing bowl, combine the cake mix, oil, eggs, and reserved pineapple juice. Mix on low speed for 30 seconds.
Then beat on medium speed for 2 minutes, scraping the bowl regularly.
In a small dish, combine the melted butter and brown sugar.
Place 1 1/2 tablespoons butter mixture in each muffin cup.
Top with two pineapple chunks. Place the cherry half, cut side up, in the center of the pineapple slices.
Place 1/4 cup batter in each cup.
Bake for 20–25 minutes, or until a toothpick inserted in the center comes out clean.
