Creating Apple Crisp Mini Cheesecakes is simple when you follow these steps:

1. Preheat the Oven: Preheat your oven to 325°F (163°C). Line a muffin tin with cupcake liners.
2. Prepare the Apple Filling: In a medium bowl, mix the diced apples, brown sugar, cinnamon, and lemon juice. Set aside.
3. Make the Crust: In another bowl, combine the graham cracker crumbs, brown sugar, melted butter, rolled oats, and cinnamon. Stir until evenly coated.
4. Form the Crusts: Press about 2 tablespoons of the crust mixture into the bottom of each cupcake liner to form an even base.
5. Prepare the Cheesecake Filling: In a large bowl, beat the softened cream cheese and granulated sugar until smooth. Add the egg, vanilla extract, cinnamon, and flour. Mix until fully combined.
6. Assemble the Cheesecakes: Pour a generous amount of cheesecake filling over the crust in each cupcake liner. Top each cheesecake with a spoonful of the apple filling.
7. Bake: Place the muffin tin in the preheated oven and bake for 25-30 minutes or until the centers are set.
8. Cool Down: Once baked, remove from the oven and let the mini cheesecakes cool in the muffin tin for about 15 minutes. Then transfer them to a cooling rack to cool completely.
9. Chill: Once cooled, cover them with plastic wrap and refrigerate for at least 2 hours to set.
10. Serve: Once chilled, remove the mini cheesecakes from the liners and serve with whipped cream or a drizzle of caramel sauce if desired.

These steps will guide you in creating these delicious mini cheesecakes effortlessly.
