Step-by-Step Instructions
Preparation Steps
1. Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper. Leave some paper hanging over the edges. This helps lift the bars out later.
2. In a large bowl, mix wet ingredients. Beat 1 cup of softened butter with 1 cup of brown sugar and 1/2 cup of granulated sugar. Use an electric mixer for about 2-3 minutes. The mix should become light and fluffy.
3. Add in the eggs and vanilla. Mix in 2 large eggs one at a time. After each egg, ensure it’s well blended. Finally, add 2 teaspoons of pure vanilla extract and mix until combined.
4. Combine the dry ingredients. In another bowl, sift together 2 1/4 cups of flour, 1 teaspoon of baking soda, 1/2 teaspoon of salt, and 1 cup of finely crushed graham cracker crumbs. Gradually add this mix to the wet ingredients. Stir gently until no flour streaks remain.
Assembly Steps
1. Layer the cookie dough. Take half of the dough and press it evenly into the bottom of your lined pan. This will be your base.
2. Add the chocolate and marshmallow filling. Sprinkle a layer of 1 cup of semi-sweet chocolate chips and 1 cup of mini marshmallows over the base. This middle layer adds that gooey s’mores magic!
3. Top with remaining dough. Scoop small spoonfuls of the remaining dough and flatten them. Place these over the filling. It’s okay if some of the filling shows through. It makes the bars look rustic and fun!
4. Add finishing touches. Scatter some extra graham cracker pieces and chocolate chips on top for a beautiful finish.
Cooling and Serving Steps
1. Cool the bars in the pan. Once baked for 25-30 minutes, take them out of the oven. Let them cool in the pan for about 10-15 minutes.
2. Cut the bars into servings. Use the parchment overhang to lift the bars out onto a cutting board. Cut them into your desired size.
3. Suggestions for enjoying. For the best experience, serve these bars warm or at room temperature. Enjoy with a glass of cold milk for a perfect treat!
Tips & Tricks
Achieving the Perfect Texture
Softened butter is key for great cookie bars. It helps the dough mix evenly and creates a nice, chewy texture. If you forget to soften it, you can microwave it for just a few seconds.
Avoiding overmixing the dough is also important. Mix just until everything comes together. Overmixing can make the bars tough and dry.
Flavor Enhancements
Using different types of chocolate can elevate your bars. Try dark chocolate or milk chocolate for a change. You can even mix in white chocolate for a fun twist.
Adding nuts can give your bars extra crunch. Pecans or walnuts pair well with the soft marshmallows. Just chop them up and fold them into the dough.
Baking Techniques
Check for doneness after about 25 minutes. The edges should look golden brown, while the center stays soft. A toothpick test is great, but a few gooey marshmallows on it are okay!
To keep a gooey center, underbake just a little. The bars will continue to cook as they cool. They should be warm and soft when you cut into them.

Variations
Gluten-Free Options
You can make s’mores cookie bars gluten-free. Start by substituting gluten-free flour for all-purpose flour. Look for a good blend that has a similar texture. You may need to adjust the liquid a little. Sometimes, gluten-free flour absorbs more liquid.
Flavor Variations
Want a twist? Try using peanut butter chocolate chips instead of regular ones. This adds a rich, nutty flavor. You can also add flavored marshmallows. Think about caramel or strawberry. These options give your bars a unique taste and fun color.
Serving Suggestions
Pair your s’mores cookie bars with ice cream. A scoop of vanilla or chocolate is perfect. You can also serve them with sauces or toppings. Try hot fudge or caramel drizzle. These extras elevate the dessert to a whole new level.
Storage Info
How to Store S’mores Cookie Bars
To keep your s’mores cookie bars fresh, store them in an airtight container. This helps lock in moisture and keeps them chewy. You can stack the bars with parchment paper between layers to prevent sticking.
For the best results, place them in a cool, dry area. Avoid places with heat or sunlight, as these can dry out the bars. If you have leftovers, you can also store them in the fridge for extra freshness.
Freezing Instructions
If you want to save some bars for later, freezing is a great option. First, let the bars cool completely. Then, wrap them tightly in plastic wrap or foil. Place the wrapped bars in a freezer-safe bag or container.
