Why You’ll Love These S’mores Cookie Bars
The Classic S’mores Flavor in an Easy Dessert Bar
Traditional campfire treats taste wonderful, yet they can feel messy and slow to prepare. However, S’mores Cookie Bars turn those familiar flavors into a simple baked dessert.
Instead of assembling each s’more one by one, you layer graham cracker cookie dough, marshmallow creme, and chocolate chips in a pan. Then the oven does the rest. As a result, you get all the flavors of a campfire treat in neat dessert bars.
Soft, Chewy, and Gooey Texture Everyone Loves
Texture makes these bars special. The graham cracker cookie dough bakes into a soft and slightly crumbly base.
Meanwhile, the marshmallow creme melts into a gooey layer that stretches with every bite. At the same time, chocolate chips soften into little pockets of rich sweetness. Together, they create the irresistible texture that makes S’mores Cookie Bars disappear fast.
Perfect Make-Ahead Dessert for Parties and Gatherings
These bars also work well when you need a dessert ahead of time. You can bake them earlier in the day or even the night before.
Once cooled, the bars slice easily and travel well. Because of that, S’mores Cookie Bars make a great choice for potlucks, birthday parties, bake sales, or weekend family dinners.
What Are S’mores Cookie Bars?
The Inspiration Behind This Campfire-Inspired Dessert
Classic s’mores combine toasted marshmallows, chocolate bars, and graham crackers. Campfires create the magic.
However, bakers wanted a version that worked anytime. So dessert lovers started baking S’mores Cookie Bars, which recreate those flavors using graham cracker cookie dough instead of plain crackers.
What Makes These Bars Different from Traditional S’mores
Traditional s’mores require roasting marshmallows and assembling each sandwich.
In contrast, S’mores Cookie Bars layer everything into a baking pan. The dough forms a cookie base while marshmallow creme and chocolate chips melt inside. Because of this method, the bars turn soft, chewy, and slightly crumbly after baking.
Ingredients You Need for S’mores Cookie Bars
Cookie Dough Base Ingredients
To create the graham cracker cookie dough, gather the following ingredients:
- 1/2 cup (113 g) unsalted butter, softened
- 3/4 cup packed light or dark brown sugar
- 1 large egg, room temperature
- 1 teaspoon vanilla extract
- 1 cup all purpose flour
- 1 cup graham cracker crumbs (about 8 graham crackers)
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
These ingredients form a soft cookie dough that tastes like graham crackers with a caramel hint from the brown sugar.
Marshmallow and Chocolate Filling
The filling brings the classic s’mores flavor.
- 1 cup semi sweet chocolate chips
- 1 heaping cup marshmallow creme
Marshmallow creme spreads easily and melts smoothly, so it creates a thick gooey layer inside the bars.
How to Make S’mores Cookie Bars Step-by-Step
Step 1: Prepare the Baking Pan and Oven
First, preheat the oven to 350°F (177°C). Meanwhile, line an 8 inch or 9 inch square baking pan with parchment paper.
Leave some parchment hanging over the sides. Later, this helps lift the S’mores Cookie Bars out of the pan.
Step 2: Cream the Butter and Brown Sugar
Next, place softened butter and brown sugar in a mixing bowl.
Beat the mixture for about three minutes until it becomes smooth and fluffy. This step builds the soft cookie texture.
Step 3: Add Egg and Vanilla for Flavor
Then add the egg and vanilla extract.
Mix again until everything blends smoothly. Also scrape the bowl if needed so the ingredients combine evenly.
Step 4: Mix the Dry Ingredients
Meanwhile, in another bowl combine:
- flour
- graham cracker crumbs
- baking powder
- salt
Stir until evenly mixed.
Step 5: Form the Sticky Graham Cracker Cookie Dough
Next add the dry mixture to the wet mixture.
Stir until a sticky dough forms. The dough should feel soft and slightly thick.
Step 6: Press the Dough Base into the Pan
Now press about two thirds of the dough into the prepared pan.
Use your hands or a spatula to create a thin, even layer. The dough may feel sticky, which is normal for S’mores Cookie Bars.
Step 7: Add Marshmallow Creme and Chocolate Chips
Next spread the marshmallow creme evenly over the dough layer.
Then sprinkle chocolate chips across the marshmallow layer.
Step 8: Add the Top Dough Layer
Flatten small portions of the remaining dough.
Place these pieces across the chocolate layer. Leave small gaps so some chocolate and marshmallow stay visible after baking.
Step 9: Bake Until Lightly Golden
Bake the bars for 25 to 30 minutes.
The top should turn lightly golden and the edges should look set.
Step 10: Cool Completely and Slice into Bars
After baking, allow the pan to cool completely on a rack.
Then lift the parchment out and cut the S’mores Cookie Bars into squares.
Tips for Perfect S’mores Cookie Bars
Why Marshmallow Creme Works Better Than Marshmallows
Regular marshmallows melt into the dough during baking. As a result, they disappear instead of forming a layer.
However, marshmallow creme stays soft and spreadable. Because of this, S’mores Cookie Bars keep their gooey center.
How to Handle the Sticky Dough Easily
The dough often feels sticky because of the graham cracker crumbs and butter.
However, lightly wetting your fingers or using parchment paper makes pressing the dough much easier.
How to Get Clean, Neat Bar Slices
Cooling fully helps the bars set.
Then use a sharp knife and wipe the blade between cuts. As a result, your S’mores Cookie Bars will have clean edges.
Variations and Substitutions
Using Digestive Biscuits Instead of Graham Crackers
Sometimes graham crackers are hard to find.
In that case, finely crushed digestive biscuits work well. They create a similar flavor and texture in the cookie dough.
Trying Different Chocolate Options
Semi sweet chocolate chips create a balanced sweetness.
However, milk chocolate chips or chopped chocolate bars also work well in S’mores Cookie Bars.
Doubling the Recipe for a Larger Pan
If you need more servings, double the recipe.
Bake the bars in a 9 by 13 inch pan instead. Then increase the baking time to about 35 to 38 minutes.
Storage, Freezing, and Make-Ahead Tips
How to Store S’mores Cookie Bars at Room Temperature
Store the bars in an airtight container at room temperature.
They stay fresh for up to one week.
How to Freeze the Bars for Later
These bars freeze very well.
First cool them fully. Then slice and layer them with parchment in an airtight container. Freeze for up to three months.
Best Way to Thaw and Serve
Place frozen S’mores Cookie Bars in the refrigerator overnight.
By the next day they will thaw perfectly and taste just as soft and chewy.
