Ingredients

Scale

Cookie Base

1 cup Unsalted butter, softened
1 cup Brown sugar, packed
1/2 cup Granulated sugar
2 Large eggs
1 teaspoon Vanilla extract
2 1/2 cups All-purpose flour
1 teaspoon Baking soda
1/2 teaspoon Salt
1 cup Graham cracker crumbs
1 cup Chocolate chips
1 cup Mini marshmallows

Topping

Extra chocolate chips, to taste
Extra mini marshmallows, to taste

Instructions

Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan or line it with parchment paper to ensure easy removal of the cookie bars after baking.
Cream Butter and Sugars: In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar using a mixer until the mixture is light, fluffy, and well combined, setting the foundation for a tender cookie base.
Add Eggs and Vanilla: Beat in the eggs one at a time, fully incorporating each before adding the next. Stir in the vanilla extract to infuse the dough with rich flavor.
Mix Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt, ensuring even distribution of the leavening agent and salt throughout the dough.
Combine Dry and Wet Mixtures: Gradually add the dry ingredients to the wet mixture, mixing gently just until combined to avoid overworking the dough, which could lead to tough bars.
Fold in Crunch and Chocolate: Gently fold in the graham cracker crumbs and chocolate chips so that they are evenly dispersed without deflating the batter.
Layer the Dough: Spread half of the cookie dough evenly into the prepared baking pan, pressing down slightly to create a flat base layer.
Add Marshmallow Layer: Sprinkle all of the mini marshmallows over the base cookie dough layer, distributing them evenly for gooey pockets throughout.
Top with Remaining Dough: Spread the remaining cookie dough gently over the marshmallows, covering them completely but without pressing too firmly to maintain the marshmallow texture.
Add Extra Toppings: Sprinkle additional chocolate chips and mini marshmallows on top for extra gooeyness and visual appeal.
Bake: Place the pan in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean, indicating the bars are fully cooked.
Cool and Slice: Remove from the oven and allow the bars to cool in the pan for about 10 minutes. Then, lift the bars out using the parchment paper if used, transfer to a wire rack, and let cool completely before slicing into squares for serving.
Serve and Enjoy: Serve these delicious S’mores Cookie Bars to family and friends and enjoy their rich, nostalgic flavors all year round.

Notes

Use parchment paper for easy removal and cleaner slicing of bars.
Do not overmix the dough once flour is added to prevent tough cookie bars.
Add extra marshmallows near the end of baking if you prefer a gooier top layer.
Store bars in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
For a gluten-free version, substitute all-purpose flour with a gluten-free flour blend.
