How to Make S’mores Cookie Bars
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your S’mores Cookie Bars bake evenly.
Step 2: Prepare Your Baking Pan
Line a 9×13 inch baking pan with parchment paper for easy removal. This step helps keep the bars intact when serving.
Step 3: Cream the Butter and Sugars
In a mixing bowl, beat together the softened butter, brown sugar, and granulated sugar until light and fluffy. This will take about 2-3 minutes using an electric mixer.
Step 4: Add Eggs and Vanilla
Add the large eggs one at a time, mixing well after each addition. Then stir in the vanilla extract until fully combined.
Step 5: Combine Dry Ingredients
In another bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this mixture to the wet ingredients until just combined.
Step 6: Fold in Graham Crackers and Chocolate Chips
Gently fold in the graham cracker crumbs, chocolate chips, and mini marshmallows until distributed throughout the dough.
Step 7: Bake the Bars
Spread the mixture evenly in your prepared baking pan. Bake in preheated oven for about 30 minutes or until golden brown around the edges.
Step 8: Cool and Serve
Allow your S’mores Cookie Bars to cool in the pan before cutting into squares. Optionally top with extra chocolate chips and marshmallows while still warm for an extra treat! Enjoy!
How to Serve S’mores Cookie Bars
S’mores Cookie Bars are perfect for sharing at gatherings and parties. Their chewy texture and sweet flavor make them a crowd-pleaser. Here are some ideas on how to serve them for the best experience.
Individual Portions
- Cut the bars into squares or rectangles for easy serving. This way, guests can grab a piece without any fuss.
À la Mode
- Serve warm S’mores Cookie Bars with a scoop of vanilla ice cream on top. The creamy contrast pairs beautifully with the sweet cookie bars.

How to Perfect S’mores Cookie Bars
To ensure your S’mores Cookie Bars turn out delicious every time, consider these handy tips.
- Use fresh ingredients: Fresh butter, eggs, and chocolate chips enhance flavor and texture.
- Chill the dough: Letting the dough chill for about 30 minutes helps prevent spreading during baking.
- Don’t overbake: Keep an eye on the baking time; take them out when they’re slightly underbaked for a chewy center.
- Layering is key: For optimum s’mores flavor, layer extra chocolate chips and mini marshmallows on top before baking.
- Cool completely: Allow the bars to cool in the pan before cutting; this helps them set up nicely.
- Store properly: Keep leftover bars in an airtight container to maintain their freshness for longer.
Best Side Dishes for S’mores Cookie Bars
S’mores Cookie Bars can be complemented by various side dishes that enhance their sweetness or provide balance. Here are some tasty ideas to consider.
-
Fresh Fruit Salad
A mix of seasonal fruits offers a refreshing contrast to the rich flavors of cookie bars. -
Chocolate Fondue
Serve with skewers of fruit, marshmallows, or pretzels for dipping into warm chocolate, adding fun and variety. -
Ice Cream Sundae Bar
Set up toppings like nuts, sprinkles, and syrups so guests can create their own sundaes alongside the cookie bars. -
Coffee or Hot Chocolate
A warm beverage can balance out dessert while providing comfort on chilly evenings. -

These rich treats add another layer of sweetness without overwhelming the palate. -
Mini Pretzel Bites

Common Mistakes to Avoid
To ensure your S’mores Cookie Bars turn out perfectly, avoid these common pitfalls.
- Ignoring ingredient temperature: Using cold butter or eggs can lead to uneven mixing. Always use softened butter and room temperature eggs for the best texture.
- Not measuring flour correctly: Scooping flour directly from the bag can pack it down, resulting in too much flour. Use the spoon-and-level method for accurate measurements.
- Overmixing the dough: Mixing the cookie dough too much can make your bars tough. Mix just until combined for a chewy texture.
- Skipping parchment paper: Not lining your baking dish can make it hard to remove the bars later. Always use parchment paper for easy lifting and cleanup.
- Not letting them cool: Cutting into them too soon can cause them to crumble. Allow your S’mores Cookie Bars to cool completely before slicing.
