Creating your S’mores Cheesecake Bars is an enjoyable process when you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 325°F (165°C). Line a 9×9-inch baking dish with parchment paper, leaving some overhang for easy removal later.
2. Make the Crust: In a mixing bowl, combine graham cracker crumbs and melted butter. Stir until well combined. Press this mixture firmly into the bottom of the prepared baking dish to form an even layer.
3. Bake the Crust: Place the crust in the oven and bake for 10 minutes or until slightly golden. Remove from the oven and allow it to cool.
4. Prepare the Cheesecake Filling: In a large mixing bowl, beat the softened cream cheese until smooth. Gradually add the sugar and mix until well incorporated.
5. Add Eggs and Vanilla: Add the eggs one at a time, mixing well after each addition. Then, stir in the vanilla extract until everything is evenly combined.
6. Combine Chocolate and Marshmallows: Gently fold in the mini marshmallows and milk chocolate chips into the cheesecake mixture.
7. Pour Filling Over Crust: Pour the cheesecake filling over the cooled graham cracker crust, spreading it evenly with a spatula.
8. Bake: Bake in the preheated oven for 30-35 minutes, or until the center is mostly set but may still slightly jiggle. The edges should look firm and lightly golden.
9. Cool Completely: Remove from the oven and let the bars cool at room temperature for about an hour. Then, refrigerate for at least two hours to set completely.
10. Add Toppings: If desired, spread marshmallow cream over the top for added sweetness and an authentic s’mores finish.
11. Cut and Serve: Lift the bars out of the pan using the parchment paper overhang, cut into squares, and serve.
