How to Make S’mores Cookie Bars
Follow these straightforward steps for perfect results. Total time is under 40 minutes from start to finish.
Step 1: Prepare Pan and Base
First, preheat your oven to 375°F (190°C). Line a 13×9-inch pan with parchment paper, leaving overhang on two sides for easy removal. Arrange whole graham crackers in a single layer, breaking them to fill gaps completely.
Step 2: Make Cookie Dough
Cream butter and sugars until fluffy in a stand mixer. Add eggs and vanilla, mixing until incorporated. In another bowl, whisk flour, salt, and baking soda. Gradually add dry ingredients to wet mixture until just combined. Fold in chocolate chips and most marshmallows, reserving some for topping.
Step 3: Assemble and Bake
Spread dough evenly over graham crackers using wet fingers or a spatula. Top with reserved marshmallows. Bake 25-30 minutes until golden – tent with foil if browning too quickly. Immediately place chocolate squares over warm bars after removing from oven.
Pro Tips for Success
Use these professional techniques for flawless bars every time.
Texture Control
For chewier bars, slightly underbake and let cool completely in pan. For crunchier edges, bake the full 30 minutes. Always press dough firmly to prevent air pockets.
Prevent Sticking
Generously butter the parchment paper underneath graham crackers. Run a knife along pan edges after removing from oven to ensure clean cuts later.
Flavor Variations
Candy Mix-Ins
Substitute chopped peppermint patties, peanut butter cups, or caramel bites for chocolate chips. Crushed toffee bits add delightful crunch when sprinkled before baking.
Nutty Upgrade
Add chopped walnuts or pecans for earthy contrast. Toast nuts first for deeper flavor. Alternatively, swirl peanut butter into the cookie dough before spreading.
Serving Suggestions
These versatile bars fit various occasions. Serve warm with vanilla ice cream for decadent desserts. Cut into small squares for birthday party trays. Pair with coffee during brunch gatherings.

Storage and Freezing Instructions
Room Temperature Storage
Store cooled bars in an airtight container at room temperature for 3 days. Place wax paper between layers to prevent sticking.
Freezing Method
Wrap individual bars tightly in plastic wrap, then place in freezer bags for up to 2 months. Thaw at room temperature before serving warm.

FAQs About S’mores Cookie Bars
Can I make these gluten-free?
Use gluten-free graham crackers and measure flour with a scale. Choose a 1:1 gluten-free flour blend with xanthan gum for best consistency.
Why did my marshmallows disappear?
Mini marshmallows melt significantly during baking. For prominent marshmallow presence, add extra during last 5 minutes of baking or torch after cooling.
Can I use different pans?
A metal pan yields crispier edges, while glass pans make softer bars. For golden bites try our crispy air fryer hash brown patties using alternative cookware effectively.
