- large eggs (2) — at room temperature helps create a smoother batter.
- vanilla extract (1 teaspoon) — enhances overall flavor; use pure for the best taste.
- graham cracker crumbs (2 cups) — crush your own crackers for a fresher taste.
- baking powder (1 teaspoon) — don’t skip this, it helps the bars rise nicely.

For the Filling:
- mini marshmallows (2 cups) — ensure they’re evenly distributed for gooey bites.

How to Make smores bars
1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish. You’ll know it’s ready when the air is warm and inviting.
2. Mix Wet Ingredients: In a large bowl, combine the melted butter, brown sugar, granulated sugar, eggs, and vanilla extract. Mix until smooth and creamy.
3. Combine Dry Ingredients: In another bowl, whisk together the graham cracker crumbs, baking powder, and salt. This adds structure to your smores bars.
4. Combine Mixtures: Gradually add the dry mixture to the wet mixture until just combined. Don’t overmix; it could lead to dense bars instead of soft ones.
5. Layer Filling: Spread half of the batter in the prepared dish. Then sprinkle mini marshmallows and chocolate chips evenly on top. Pour the remaining batter over everything.
6. Bake Bars: Bake for 25-30 minutes until the edges pull away from the pan and the center is set but slightly gooey in the middle — that’s how you want it!
7. Cool & Slice: Let your smores bars cool completely in the pan before slicing into squares for easy serving. Watch out — cutting them too soon may lead to a messy situation!

How to Store smores bars
- Room Temperature: Store smores bars in an airtight container for up to 3 days. They’ll stay soft and chewy but can get a little sticky.
- Refrigerator: Keep them in a sealed container for about a week. Just know that the crispy topping softens in the fridge, so they lose some crunch.
- Freezer: Wrap individual bars in plastic wrap and then place them in a freezer bag for up to 2 months. They’ll freeze well, but the texture might change slightly when thawed.
- Reheating: Warm in the oven at 350°F for about 5-10 minutes or until they’re gooey and the chocolate is melty. This helps restore some of that original texture, but they may not be quite as fresh as when made.

Make Ahead Options for smores bars
I love prepping my smores bars ahead of time for gatherings. I usually make the base a day or two in advance and store it in an airtight container at room temperature. Just be sure to let it cool completely before sealing it up. The mini marshmallows and chocolate chips, however, are best added right before serving to keep them fresh and gooey. I find that the base holds up well for about three days, but if you add the filling too early, it can get a bit soggy. So remember, make that delicious base ahead but save the toppings for last! Enjoy your sweet creation!
smores bars Recipe FAQs
Can I make smores bars ahead of time?
Absolutely! You can prepare smores bars a day in advance. Just follow the recipe, let them cool completely, and store them in an airtight container at room temperature. They’ll stay delicious for about 2-3 days. If you want to keep them fresh longer, consider refrigerating them. Just remember to let them come to room temperature before serving for the best texture.
Why did my smores bars turn out too dry?
If your smores bars turned out dry, it’s likely they were overbaked or the ratio of wet to dry ingredients was off. Make sure to check for doneness around the 25-minute mark; the top should be golden brown but still slightly soft in the middle. Don’t hesitate to underbake them slightly, as they’ll continue cooking while cooling. A moist bar is key!
What can I substitute for graham cracker crumbs in this dish?
If you don’t have graham cracker crumbs, crushed digestive biscuits or vanilla wafers are great substitutes! Both will give a similar sweet and crumbly base that complements the chocolate and marshmallows perfectly. Just ensure you measure out two cups after crushing them for consistent results. You might want to adjust sugar levels slightly if your substitute is sweeter.
How do I know when this recipe is done baking?
You’ll know your smores bars are done when they’re golden brown on top and a toothpick inserted into the center comes out with a few moist crumbs—not wet batter. Letting them cool in the pan helps firm up their structure too. Keep an eye on that golden color; it’s a good indicator of perfect baking!
