Prepare the Oven and Pan: Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners. This temperature will allow for even baking of both the crust and filling, while the liners make it easy to remove and serve the cheesecake cups.
Make the Graham Cracker Crust: In a bowl, mix the graham cracker crumbs, sugar, and melted butter until thoroughly combined. The mixture should resemble wet sand and hold together when pressed between your fingers. This forms the foundation of your dessert with a sweet, buttery flavor.
Form the Crusts: Press about a tablespoon of the graham cracker mixture into the bottom of each cupcake liner, creating an even layer. Use the back of a spoon or a small measuring cup to firmly press the mixture down to form a compact crust that will hold together.
Pre-bake the Crusts: Bake the crusts for 5-7 minutes until they become lightly golden and set. This short baking time helps the crust hold its shape and adds a toasty flavor. Set aside to cool while preparing the filling.
Make the Cheesecake Filling: In a large bowl, beat the softened cream cheese and sugar until smooth and fluffy, about 2-3 minutes. Make sure there are no lumps in the mixture for a silky-smooth cheesecake texture.
Complete the Cheesecake Mixture: Add the vanilla extract, egg, and sour cream to the cream cheese mixture, and continue to beat until creamy and well combined. The sour cream adds moisture and a subtle tanginess that balances the sweetness.
Fill the Cups: Spoon the cheesecake mixture over the cooled crusts, filling each cup about 3/4 full. Leave some space at the top for the peach cobbler topping. Use a spoon to smooth the surface of each cheesecake.
Prepare the Peach Cobbler Topping: In a separate bowl, combine the diced peaches, brown sugar, cinnamon, nutmeg, melted butter, flour, and oats (if using). Mix until the peaches are well coated and the topping has a crumbly texture. The spices will infuse the peaches with warm, aromatic flavors.
Add the Topping: Spoon a generous amount of the peach mixture over the cheesecake layer in each cup. Distribute the topping evenly, making sure each cup gets plenty of peach pieces.
Bake the Cheesecake Cups: Bake in the preheated oven for 20-25 minutes, or until the cheesecake is set and the cobbler topping is golden. The centers may still be slightly jiggly but will firm up as they cool.
Cool the Cups: Remove from the oven and allow to cool completely in the pan. The cooling process is important for the cheesecake to set properly and develop its texture.
Chill Before Serving: Once cooled to room temperature, chill the cheesecake cups in the refrigerator for at least 2 hours before serving. This final chilling step ensures the cheesecakes are properly set and enhances their flavor.
Garnish and Serve: Top each cup with a dollop of whipped cream and a sprinkle of cinnamon for garnish just before serving. The whipped cream adds a light, creamy element that complements the rich cheesecake and fruity topping.
