Step 1: Prepare the Pineapple Layer

1. Preheat oven to 325°F (163°C).
2. Grease a 9-inch springform pan.
3. Pour melted butter into the bottom of the pan and sprinkle with brown sugar.
4. Arrange pineapple slices in a single layer on top of the butter mixture.
5. Place maraschino cherries in the center of each pineapple slice.

Step 2: Make the Cheesecake Crust

1. In a bowl, mix graham cracker crumbs, melted butter, and sugar until well combined.
2. Press the mixture firmly into the bottom and slightly up the sides of the pan.

Step 3: Prepare the Cheesecake Filling

1. Beat cream cheese and sugar together until smooth and creamy.
2. Add eggs, one at a time, mixing after each addition.
3. Stir in vanilla extract and sour cream, mixing until just combined.

Step 4: Assemble & Bake

1. Pour the cheesecake batter over the pineapple slices in the pan.
2. Place the cheesecake pan inside a larger roasting pan and pour hot water around it (about 1 inch deep) for a water bath.
3. Bake for 50-60 minutes, or until the center is slightly jiggly but set.

Step 5: Cool & Serve

1. Let the cheesecake cool in the oven with the door slightly open for 30 minutes.
2. Transfer to the fridge and chill for at least 4 hours or overnight.
3. Once chilled, carefully invert onto a serving plate so the pineapple layer is on top.
4. Slice and enjoy!
