Ingredients

Tip: You can find the complete list of ingredients and their measurements in the recipe card below.

All-Purpose Flour provides the structure for the cookie bars while keeping the texture soft and chewy. Measuring the flour accurately helps prevent dense bars.

Baking Powder gives the cookie dough a gentle lift, creating a tender texture without making the bars cakey.

Salt balances the sweetness while enhancing the flavors of the butter, chocolate, and marshmallows.

Unsalted Butter creates a rich, buttery base and contributes to the soft texture. Using softened butter allows it to cream smoothly with the sugars.

Brown Sugar adds moisture and a subtle caramel flavor that complements the graham crackers and chocolate beautifully.

Granulated Sugar provides sweetness while helping the edges become lightly crisp during baking.

Eggs bind the ingredients together and help create a soft, chewy crumb.

Vanilla Extract enhances the overall flavor and adds warmth that pairs perfectly with the chocolate.

Graham Crackers provide the signature crunch and classic s’mores flavor. Broken pieces throughout the bars create wonderful texture.

Milk Chocolate Bars deliver the traditional s’mores experience with smooth, creamy chocolate that melts beautifully during baking.

Semi-Sweet Chocolate Chips add extra chocolate flavor while balancing the sweetness of the marshmallows.

Mini Marshmallows become perfectly gooey and lightly toasted in the oven, creating the classic s’mores texture everyone loves.

How to Make

Preheat your oven to 350°F (175°C) and lightly grease or line a 9×13-inch baking pan with parchment paper for easy removal.

In a medium bowl, whisk together the flour, baking powder, and salt until evenly combined.

In a separate large mixing bowl, beat the softened butter, brown sugar, and granulated sugar until the mixture becomes light and fluffy. Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.

Gradually add the dry ingredients to the wet ingredients, mixing just until a soft cookie dough forms. Avoid overmixing to keep the bars tender.

Spread about two-thirds of the cookie dough evenly into the prepared baking pan. Arrange the graham cracker pieces over the dough, followed by the milk chocolate bars and semi-sweet chocolate chips. Sprinkle the mini marshmallows evenly across the top.

Drop spoonfuls of the remaining cookie dough over the filling. It doesn’t need to completely cover the marshmallows, as leaving small gaps allows the gooey filling to peek through after baking.

Bake for 28 to 35 minutes, or until the edges are golden brown and the center is just set. If the marshmallows begin browning too quickly, loosely cover the pan with foil during the final few minutes of baking.

Allow the bars to cool completely before slicing into squares. This helps the chocolate set slightly while keeping the center deliciously soft and gooey.

Common Mistakes to Avoid

• Overbaking the cookie bars.
• Overmixing the dough.
• Using cold butter instead of softened butter.
• Cutting the bars before they cool.
• Packing the flour too tightly.
• Using stale graham crackers.
• Overfilling with marshmallows.
• Skipping parchment paper for easy removal.

Storage/Reheating

Store the cookie bars in an airtight container at room temperature for up to 4 days or in the refrigerator for up to one week. For a freshly baked texture, warm individual bars in the microwave for 10 to 15 seconds before serving. You can also freeze the bars for up to 3 months by wrapping them individually and storing them in a freezer-safe container.

Variations and Customizations

One of the best things about S’mores Cookie Bars is how easy they are to customize. Whether you’re baking for a special occasion or simply experimenting with new flavors, there are plenty of creative ways to make this recipe your own.

Try using dark chocolate, white chocolate, caramel-filled chocolate bars, or peanut butter cups in place of traditional milk chocolate. Each option creates a unique twist while maintaining the classic s’mores experience.

Mix additional ingredients into the cookie dough such as chopped pecans, walnuts, toffee bits, mini chocolate chips, or crushed pretzels for extra texture and flavor.

If you enjoy a richer dessert, drizzle melted chocolate or caramel sauce over the cooled bars before serving. A light sprinkle of flaky sea salt also enhances the sweetness while creating a gourmet finish.

For a festive version, decorate the bars with colorful sprinkles or seasonal candies for holidays and celebrations.

Swap the vanilla extract for almond extract or add a teaspoon of cinnamon for a subtle flavor variation that pairs wonderfully with the graham crackers.

Mini marshmallows work best, but regular marshmallows cut into smaller pieces can also be used if needed.

Serve these cookie bars slightly warm with a scoop of vanilla ice cream or a dollop of whipped cream for an indulgent dessert. They also pair perfectly with coffee, hot chocolate, or a cold glass of milk.

Because they travel well and stay soft for several days, these cookie bars are an excellent choice for potlucks, lunchboxes, bake sales, and family gatherings.
