Ingredients Needed for This S’mores Cookie Bars Recipe
- 1 cup unsalted butter softened to room temperature
- 1 cup brown sugar packed
- ½ cup granulated sugar
- 2 large eggs
- 1 teaspoon pure vanilla extract
- 2½ cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon salt
- 1 cup graham cracker crumbs
- 1 cup chocolate chips
- 1 cup mini marshmallows
- Extra chocolate chips and mini marshmallows for topping
How to Make This S’mores Cookie Bars Recipe
Step 1: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan generously with butter or nonstick spray, or line it with parchment paper for the easiest possible removal and cleanup.
Step 2: In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar using a hand mixer or stand mixer. Beat for 2 to 3 minutes until the mixture is light, pale, and fluffy. This step is essential for achieving that perfect chewy texture.
Step 3: Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract until the batter looks smooth and creamy.
Step 4: In a separate bowl, whisk together the flour, baking soda, and salt until evenly combined to ensure the baking soda distributes evenly throughout.
Step 5: Gradually add the dry flour mixture to the butter mixture, stirring gently until just combined. Do not overmix as overworking the dough leads to tough dense bars instead of soft and chewy ones.
Step 6: Fold in the graham cracker crumbs and chocolate chips until evenly distributed throughout the dough.
Step 7: Press half of the cookie dough evenly into the bottom of your prepared pan, creating a smooth even base layer.
Step 8: Scatter the mini marshmallows evenly over the dough layer, then carefully spoon the remaining dough on top and gently press it down to cover the marshmallows as much as possible.
Step 9: Scatter extra chocolate chips and mini marshmallows generously over the top for that golden gooey irresistible finish.
Step 10: Bake for 25 to 30 minutes until the top is beautifully golden brown and a toothpick inserted into the center comes out with just a few moist crumbs. Cool in the pan for 10 minutes then transfer to a wire rack to cool completely before slicing into squares.
How to Serve This S’mores Cookie Bars Recipe
Cut these bars into generous squares and serve them slightly warm for the ultimate gooey experience. A scoop of vanilla ice cream alongside a warm bar is an absolutely divine pairing. For a more decadent presentation, drizzle a little melted chocolate over the top just before serving. These bars are perfect for stacking on a dessert platter at parties or individually wrapping as homemade gifts. A tall glass of ice cold milk alongside is practically mandatory.
How to Store This S’mores Cookie Bars Recipe
Store completely cooled bars in an airtight container at room temperature for up to 5 days. They retain their chewy texture beautifully throughout. For longer storage, refrigerate for up to a week though the texture becomes slightly firmer when cold. To reheat, microwave a single bar for 10 to 15 seconds for that warm gooey fresh-baked experience all over again. These bars also freeze well for up to 2 months wrapped individually in plastic wrap inside a freezer bag.
Tips to Make This S’mores Cookie Bars Recipe
Make sure your butter is truly softened to room temperature before creaming, as this forms the foundation of the right chewy texture. Cold butter will not cream properly and results in a denser less tender bar. Do not overbake these bars. They will look slightly underdone in the center when you pull them from the oven, but they continue to set beautifully as they cool. Pulling them out a minute or two early ensures that perfect soft gooey center that makes these bars so spectacular.
Helpful Notes for This S’mores Cookie Bars Recipe
Graham cracker crumbs are incredibly easy to make at home. Simply place graham crackers in a zip-lock bag and crush them with a rolling pin until finely crumbled, or pulse briefly in a food processor for more even consistent crumbs. If you can only find large marshmallows, simply snip them into smaller pieces using kitchen scissors lightly coated with nonstick spray to prevent sticking.
Variation of This S’mores Cookie Bars Recipe
For a truly over-the-top version, swap the regular chocolate chips for dark chocolate chips or a combination of dark and milk chocolate. The slight bitterness of dark chocolate creates a beautiful contrast against the sweetness of the marshmallows and brown sugar dough. For a nutty twist, fold in ½ cup of chopped toasted pecans or walnuts along with the chocolate chips. A peanut butter version is also spectacular: swirl 3 tablespoons of creamy peanut butter into the top layer of dough before baking for a peanut butter s’mores bar that is completely irresistible.
FAQs About This S’mores Cookie Bars Recipe
Can I make these bars gluten-free?
Yes! Simply substitute the all-purpose flour with a 1-to-1 gluten-free baking flour blend and use gluten-free graham crackers. The result is just as delicious and chewy.
Why did my bars come out cakey instead of chewy?
Cakey bars are usually the result of overmixing the dough or measuring too much flour. Spoon flour into your measuring cup and level with a knife rather than scooping directly, which compacts the flour and adds more than intended.
Can I double this recipe?
Absolutely. Double all ingredients and bake in two separate 9×13 pans or one larger sheet pan. Check for doneness a few minutes earlier if using a thinner spread layer.
Conclusion
These S’mores Cookie Bars are pure unapologetic joy in dessert form. They bring back all the warmth and nostalgia of a campfire s’more while being incredibly easy to bake right in your own kitchen any time of year. Whether you share them with a crowd or keep the whole pan joyfully to yourself, one thing is absolutely certain: they will not last long.
