Making S’more Bars is as easy as following these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and prepare a 9×13-inch baking pan by greasing it or lining it with parchment paper.
2. Cream Butter and Sugars: In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
3. Add Eggs and Vanilla: Beat in the eggs one at a time and mix in the vanilla extract until well combined.
4. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, and salt.
5. Mix Dry and Wet Ingredients: Gradually add the dry ingredients to the wet mixture, stirring until fully incorporated.
6. Add Graham Cracker Crumbs: Fold in the graham cracker crumbs, chocolate chips, and marshmallows until evenly distributed throughout the mixture.
7. Pour into Pan: Evenly spread the batter into the prepared baking pan, smoothing it out with a spatula.
8. Bake: Place the pan in the oven and bake for 25-30 minutes, or until the edges are golden brown and a toothpick inserted comes out clean.
9. Cool: Once baked, remove the pan from the oven and allow it to cool in the pan for at least 30 minutes. For easier cutting, transfer to the refrigerator to cool further if desired.
10. Cut and Serve: Once cooled, cut the bars into squares and serve. Optionally, top with extra chocolate chips for an appealing finish.
