Creating S’more Bars can be straightforward if you follow these essential steps:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C). Grease an 8×8-inch baking dish with cooking spray or butter.
2. Prepare Crust Mixture: In a mixing bowl, combine graham cracker crumbs, melted butter, granulated sugar, and salt. Mix well until the mixture resembles wet sand.
3. Press Down: Firmly press the crust mixture into the bottom of the prepared baking dish, ensuring an even layer.
4. Bake the Crust: Place the crust in the preheated oven and bake for 10 minutes or until lightly golden. Remove from the oven and let it cool for a few minutes.
5. Layer Chocolate Chips: Evenly spread the semi-sweet chocolate chips over the partially baked crust, ensuring all areas are covered.
6. Add Mini Marshmallows: Sprinkle the mini marshmallows over the chocolate chips, covering as much of the area as possible.
7. Return to Oven: Bake again for an additional 15 minutes or until the marshmallows turn golden brown and puffed.
8. Cool the Bars: Remove from the oven and allow the S’more Bars to cool in the pan for about 30 minutes.
9. Cut and Serve: Once cooled, use a sharp knife to cut into squares and serve.

These steps will lead you to beautifully baked S’more Bars that are sure to impress everyone.
