1-First Step: Preheat and Prep the Pan Heat your oven to 325°F. Grease a 12-cup muffin tin generously with butter or non-stick spray. This prevents sticking and ensures easy release after baking. For gluten free assurance, double-check your crumbs.

2-Second Step: Make the Crust Mix 1 cup gluten free graham cracker crumbs, 3 tbsp melted butter, and 2 tbsp sugar in a bowl until it resembles wet sand. Press 1 tablespoon firmly into the bottom of each muffin cup using a spoon or small glass. This creates a solid base for your pineapple upside down cheesecakes. Bake the crusts alone for 5 minutes to set, then cool slightly.

3-Third Step: Add the Toppings Spoon 1 teaspoon brown sugar into each cup over the crust. Place one small drained pineapple ring on top, centering it. Add a maraschino cherry in the middle of each pineapple. Pat everything dry if using fresh pineapple to avoid excess moisture. This layer will caramelize beautifully, defining the upside down effect.

4-Fourth Step: Prepare the Cheesecake Filling In a large bowl, beat 16 oz softened cream cheese with 1/2 cup sugar until smooth and creamy, about 2 minutes. Add eggs one at a time, mixing on low speed after each to prevent air bubbles. Stir in 1 tsp vanilla extract and 1/4 cup sour cream gently. For neatness, transfer to a piping bag. Pipe or spoon about 2 tablespoons filling over each topping, filling to the top of the muffin cup. Smooth the tops if desired.

5-Fifth Step: Bake the Mini Cheesecakes Bake at 325°F for 20-25 minutes. Look for edges set and centers slightly jiggly, like Jell-O. Avoid overbaking to keep them creamy. Turn off the oven, crack the door, and let them cool inside for 10 minutes to prevent cracks. For dietary tweaks, vegan versions may need 2-3 extra minutes.

6-Final Step: Cool, Chill, and Invert Cool in the tin on a wire rack for 10 minutes. Run a thin knife around edges to loosen. Refrigerate for at least 2 hours, or overnight for best flavor. Invert onto a plate by placing a tray over the tin and flipping. Garnish with whipped cream if you like. Serve chilled. These hold up well for parties and adapt easily to low-calorie by skipping extras.
