Mini Pineapple Upside-Down Cakes

In a small bowl, combine the brown sugar and butter; mix well. Spoon into 24 greased muffin cups. Drain pineapple, reserving the juice. Trim pineapple to fit the muffin cups; place one ring in each cup.

In a large mixing bowl, combine the cake mix, eggs, oils and 1-1/4 cups of the reserved pineapple juice; mix well. Spoon over pineapple, filling each cup two-thirds full. Bake at 350 degrees F for 20-25 minutes or until a toothpick comes out clean.

Immediately invert onto wire racks to cool. Place a cherry in the center of each pineapple ring.
