How to Make S’mores Bars (Step-by-Step)
Follow these simple steps to create the perfect S’mores Bars that everyone will love.
Step 1: Prepare the Baking Dish
Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan. Alternatively, line it with parchment paper for easy removal of the bars.
Step 2: Make the Batter
In a large mixing bowl, combine the melted butter, brown sugar, and granulated sugar. Whisk until glossy and well mixed. Add the eggs one at a time, fully incorporating each before adding the next. Stir in the vanilla extract for an aromatic touch.
Step 3: Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually fold the dry mixture into the wet ingredients until just combined; avoid overmixing.
Step 4: Add Graham Crackers
Fold in the graham cracker crumbs to the batter and mix gently. This will give your bars the iconic S’mores flavor.
Step 5: Layer the Filling
Spread half of the batter in the bottom of the prepared pan. Sprinkle with milk chocolate chips and mini marshmallows before topping with the remaining batter, ensuring the filling is mostly covered.
Step 6: Bake
Bake in the preheated oven for 25-30 minutes until the edges turn golden brown. The center should be set with a slight jiggle. Release your kitchen from the intoxicating aroma of melted chocolate and marshmallows!
Step 7: Add Topping
Upon removing from the oven, sprinkle the additional chocolate chips over the hot bars, allowing them to melt slightly. Use a spatula to spread the melted chocolate evenly.
Step 8: Cool and Slice
Let the bars cool completely in the pan before slicing into squares or rectangles. Enjoy the fruits of your labor!

Common Mistakes to Avoid
- Overmixing the batter: This can lead to tough bars, so mix just until combined.
- Skipping the cooling time: Cutting the bars too early can cause them to fall apart, so be patient!
- Not using enough chocolate or marshmallows: More is more when it comes to these ingredients for that authentic S’mores experience.
Tips and Tricks for Success
- For a richer flavor, consider using dark chocolate chips along with milk chocolate.
- If you prefer a more decadent touch, add a sprinkle of sea salt on top before baking.
- These bars can be stored in an airtight container at room temperature for up to a week, but they’re best enjoyed fresh!
Variations
- Substitute graham cracker crumbs with crushed Oreo cookies for a chocolatey twist.
- Use a combination of milk and dark chocolate chips for a more complex flavor.
- Add peanut butter chips for an additional layer of flavor.
How to Serve
- Serve warm with a scoop of vanilla ice cream on top for a delicious dessert.
- Pair with hot cocoa or coffee for a cozy treat.
- Cut into small squares and serve as a party or holiday treat.

Make Ahead and Storage
- Make Ahead: Prepare the batter and filling in advance; store separately in the refrigerator for up to 2 days.
- Storage: Keep leftover bars in an airtight container at room temperature for up to a week.
- Reheating: Warm individual bars in the microwave for a few seconds to soften them.
- Freezing: Wrap cut pieces in plastic wrap and place in a freezer-safe bag for up to 3 months.
