Smores Bars

Featured in: Easy Baking Comforts

These easy dessert bars capture everything you love about classic campfire smores without the fire. A buttery graham cracker crust forms the foundation, topped with a layer of melted semi-sweet chocolate and pillowy mini marshmallows that get golden and toasted in the oven.

The bars come together in just 15 minutes of prep time and bake for 25 minutes. For the cleanest cuts, chill the bars in the refrigerator for an hour before slicing. Serve them slightly warm for maximum gooeyness, or add a pinch of sea salt to the crust for a sweet-salty contrast.

Last summer my neighbor texted at 9pm asking if I had marshmallows. Her kids were begging for s'mores but no one felt like building a fire. We ended up toasting marshmallows over her gas stove and sandwiching them between graham crackers on her back porch, laughing about how ridiculous we looked huddled around a burner. That impromptu kitchen moment inspired these bars.

I brought a pan to our block party and watched them disappear in minutes. My friend Sarah actually hid two bars in her purse to take home, then texted me the next morning demanding the recipe. Now whenever someone invites me to a potluck, they specifically ask for these.

Making Them Your Own

Once I added a layer of salted caramel between the crust and chocolate. Everyone pretended to be mad at me for ruining their diets but went back for seconds. Milk chocolate lovers should definitely swap out the semi-sweet chips.

Getting That Perfect Toast

The broiler setting can give you restaurant-quality charred marshmallow tops in about 60 seconds. Stand right there because broilers have zero chill and will burn your dreams faster than you can say fire alarm.

Storage And Serving

These keep surprisingly well in an airtight container for up to three days, though they've never lasted that long at my house. Room temperature is fine but a quick 10-second zap in the microwave brings back that fresh-baked magic.

  • Cut them while slightly chilled then let come to room temperature before serving
  • Press any loose crumbs back onto the sides for a polished look
  • Serve with napkins because sticky fingers are guaranteed

There's something about the combination of crunch, chocolate, and toasted marshmallow that makes people happy every single time.

Recipe Questions & Answers

Can I make these bars ahead of time?

Yes, these bars store well in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week. The marshmallow layer may soften slightly over time but retains great flavor.

What type of chocolate works best?

Semi-sweet chocolate chips provide the perfect balance of sweetness. You can also use milk chocolate for a sweeter bar, dark chocolate for intensity, or even chocolate bars chopped into pieces for thicker puddles of melted chocolate.

Why should I chill before cutting?

Chilling the bars for at least an hour in the refrigerator helps set the chocolate and marshmallow layers completely. This prevents the marshmallow from sticking to your knife and ensures clean, neat slices that show off the distinct layers.

Can I use a different pan size?

An 8x8-inch pan creates thick, rich bars. A 9x13-inch pan will yield thinner bars with about 24 servings instead of 16. Adjust baking time slightly—thin bars may need only 8-10 minutes for the marshmallow layer.

What if I don't have graham crackers?

Digestive biscuits, vanilla wafers, or even crushed butter cookies make excellent substitutes for the crust. Use the same quantity (1 1/2 cups crumbs) and combine with melted butter and sugar as directed.

How do I get extra toasted marshmallows?

After baking, set your oven to broil for 30-60 seconds watching constantly to prevent burning. The direct heat creates deeply golden, caramelized marshmallow tops with that authentic campfire flavor.
