Easy Mini Pineapple Upside-Down Cakes

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Grease 24 jumbo muffin cups.

Step 2
Drain pineapple rings and pour juice into a 2-cup liquid measure. Add water, if needed, to reach 2 cups. Set aside.

Step 3
Mix brown sugar and butter in a small bowl with a fork until completely combined. Divide mixture evenly between the prepared muffin cups. Place one pineapple ring in each cup and place a cherry in the center.

Step 4
Combine cake mix, reserved pineapple juice-water mixture, oil, and eggs in a large mixing bowl. Mix with an electric mixer on medium speed for 2 minutes. Fill each muffin up 2/3 full with batter.

Step 5
Bake in the preheated oven until a toothpick inserted in the centers comes out clean, 20 to 24 minutes.

Step 6
Remove from the oven and immediately invert onto wire racks to cool.
