Ingredients
Complete Ingredient List
To make Chocolate Chip S’mores Bars, gather these ingredients:
- 1 cup graham cracker crumbs
- 1/2 cup all-purpose flour
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, melted
- 1/2 cup brown sugar, packed
- 1/4 cup granulated sugar
- 1 teaspoon vanilla extract
- 1 large egg
- 1 cup semi-sweet chocolate chips
- 1 cup mini marshmallows
- 1/2 cup chocolate fudge sauce
For gluten-free options, swap the all-purpose flour for a gluten-free blend. You can use gluten-free graham crackers too. To make this recipe dairy-free, try coconut oil instead of butter and dairy-free chocolate chips.
I recommend using Ghirardelli or Nestlé chocolate chips for great taste. For fudge sauce, Hershey’s or Smucker’s are both solid choices. These brands ensure a rich flavor in your bars.

Step-by-Step Instructions
Prepping Your Ingredients
To start, gather your graham cracker crumbs. For great results, crush whole graham crackers in a bag. Use a rolling pin or your hands. You want fine crumbs for the best texture.
Next, melt your butter. Place it in a microwave-safe bowl. Heat it in short bursts, stirring in between until fully melted. This ensures it melts evenly without burning.
Now, let’s talk about the egg. For this recipe, it should be at room temperature. It mixes better with the other ingredients. If your egg is cold, place it in warm water for a few minutes to warm it up.
Mixing and Combining
First, grab two bowls. In one bowl, mix the dry ingredients: graham cracker crumbs, flour, baking soda, and salt. Stir them well so everything is even.
In the second bowl, whisk together the melted butter, brown sugar, granulated sugar, and vanilla extract. Mix until smooth. Then, beat in the room temperature egg until it is fully blended.
Now, combine the dry ingredients with the wet ones. Stir gently until just combined. Avoid overmixing to keep your bars soft. Finally, fold in the chocolate chips evenly throughout the dough.
Baking the Bars
Preheat your oven to 350°F (175°C). Grease your 9x9-inch baking pan or line it with parchment paper. This helps with easy removal later.
Pour half of the dough into the pan and spread it evenly. Next, sprinkle mini marshmallows on top, followed by drizzling chocolate fudge sauce. Pour the rest of the batter over this. Spread it gently to cover everything.
Bake your bars for 25-30 minutes. Look for a golden brown top. The edges should be set, but the center may still look a bit soft. Let them cool in the pan for 15 minutes before cutting. Enjoy your delicious creation!
Tips & Tricks
Achieving the Perfect Texture
To get the best texture, avoid overmixing your batter. Mix just until the dry and wet ingredients blend. Overmixing makes the bars tough.
Let the bars cool for at least 15 minutes before slicing. This helps them set and keeps them from falling apart. Slicing too soon can ruin their shape.
Baking Techniques
Using parchment paper helps with easy removal. It also makes cleanup quick. If you grease the pan, the bars may stick. So, parchment is usually best.
For even baking, spread the batter evenly in the pan. Make sure the oven is fully preheated. This ensures that all parts of the bars bake at the same time.
Serving and Presentation Ideas
Serve the bars warm with a scoop of vanilla ice cream. The cold ice cream melts slightly on the warm bars. This makes for a delightful treat.
Enjoy the bars straight from the pan or plate them for guests. You can also drizzle extra fudge sauce on top for added sweetness.
Pro Tips
- Use Fresh Ingredients: Always opt for fresh mini marshmallows and high-quality chocolate chips to enhance the flavor of your bars.
- Don't Overmix: When combining the wet and dry ingredients, mix until just combined to ensure a chewy texture.
- Cool Before Cutting: Allow the bars to cool completely in the pan to ensure clean cuts and prevent them from falling apart.
- Experiment with Toppings: Feel free to add nuts, different types of chocolate, or even peanut butter swirls for a unique twist on the classic s'mores flavor.
Variations
Flavor Twist Ideas
You can play with different types of chocolate for your s'mores bars. Here are some ideas:
- Use dark chocolate for a richer taste.
- Try white chocolate for a sweet twist.
- Stick with classic milk chocolate for a familiar flavor.
Adding nuts or dried fruits can bring extra texture. Consider these options:
- Chopped walnuts or pecans add crunch.
- Dried cranberries or cherries offer a sweet burst.
Seasonal Variations
Seasonal changes can inspire fun new flavors. Here are some ideas:
- Add pumpkin spice for a cozy fall treat.
- Mix in cinnamon for a warm taste in winter.
- Use peppermint bits for a festive touch during Christmas.
You can also create themed bars for holidays. For Halloween, add candy corn. For summer, use fresh fruit like strawberries.
Gluten-Free or Vegan Adaptations
If you need a gluten-free version, make these swaps:
- Use gluten-free graham crackers.
- Replace all-purpose flour with almond flour or coconut flour.
For vegan adaptations, you can substitute ingredients easily:
- Use coconut oil instead of butter.
- Replace the egg with a flaxseed egg (1 tablespoon flaxseed meal and 2.5 tablespoons water).
These changes will help you enjoy delicious s'mores bars no matter your dietary needs!
Storage Info
Best Practices for Storing Bars
To keep your chocolate chip s’mores bars fresh, you have two main options: the fridge or room temperature.
- Room Temperature: Store the bars in an airtight container. They stay good for about 3 days. Place parchment paper between layers to avoid sticking.
- Fridge: For longer storage, place them in an airtight container. They last up to a week this way. The cool air helps maintain their texture and flavor.
Freezing Instructions
If you want to save some for later, freezing is an easy option. Here’s how:
1. Cool Completely: Let the bars cool fully before freezing.
2. Cut into Squares: Slice the bars into squares for easy serving.
3. Wrap and Store: Wrap each square in plastic wrap. Then, place them in a freezer-safe bag or container. This keeps them fresh.
4. Label: Don’t forget to label the bag with the date. They stay good for about 3 months.
When you want to enjoy them again:
1. Thaw: Take the bars out of the freezer and let them thaw in the fridge overnight.
2. Reheat: If you like them warm, you can heat them in the microwave for a few seconds. Enjoy them fresh out of the oven style!
These storage tips help you keep your chocolate chip s’mores bars tasty and ready to share!
FAQs
Can I make these bars ahead of time?
Yes, you can make these bars in advance. To do this, bake the bars and let them cool completely. Once cool, cut them into squares. Place the squares in an airtight container. You can store them at room temperature for up to three days. For longer storage, keep them in the fridge for up to a week. If you want to freeze them, wrap each square in plastic wrap, then place them in a freezer bag. They will stay fresh for up to three months.
What can I substitute for graham crackers?
If you don't have graham crackers, you can use several alternatives. Try crushed digestive biscuits or vanilla wafers for a similar taste. If you want a gluten-free option, use gluten-free graham crackers or crushed almond flour cookies. You can also make a crust using oats and butter for a different flavor. Each option will change the taste slightly, but they all work well.
How do I know when the bars are done baking?
You can tell the bars are done by looking for a golden brown top. The edges should pull away from the pan slightly. If you gently press the center, it should feel set but still soft. A toothpick inserted in the center should come out mostly clean, with a few moist crumbs. Remember, they will firm up as they cool.
