S’more Nut Bars Recipe – Cozy, chocolatey squares of campfire comfort

Right away I knew these S’more Nut Bars would be a keeper, and I’ve been making them for friends ever since. This always takes me back to Sunday dinners.

Ingredients You’ll Need

• 2¼ cups graham cracker crumbs
• 1 tablespoon dark brown sugar (packed)
• ⅔ cup unsalted butter (melted)
• 7½ oz milk chocolate (roughly chopped)
• 7½ oz dark chocolate (60–72% cacao, roughly chopped)
• 1½ teaspoons light corn syrup
• 1 cup heavy cream
• 10 large marshmallows (quartered)
• ½ cup whole lightly salted peanuts
• ½ cup chopped lightly salted peanuts

Chef notes:

• Use fresh crackers for a crisp crust.
• Unsalted butter helps control salt.
• Good chocolate = better ganache.
• Quarter marshmallows for even melting.

How to Make It

1. First, preheat the oven to 300°F (150°C). Butter the bottom and sides of a 9×13-inch baking dish so the crust releases easily.
2. In a large bowl, mix the graham cracker crumbs and brown sugar. Pour in melted butter and stir until the crumbs look evenly moistened. Press firmly into the pan, pushing the crust slightly up the sides; use the bottom of a measuring cup to compact it.
3. Bake the crust 10–15 minutes, until the edges turn lightly golden and smell toasty. Remove and cool on a wire rack until barely warm. This cue matters for the ganache to set right.
4. Meanwhile, put both chocolates into a heatproof bowl and drizzle the corn syrup over them. Warm the cream in a saucepan just to a simmer — small bubbles form at the edge — then pour it over the chocolate. Let sit 2–3 minutes.
5. Next, whisk from the center outward until glossy and smooth. The ganache should be thick but pourable; if it looks grainy, whisk a little longer and the shine will return.
6. Gently fold in the quartered marshmallows and whole peanuts so they get suspended in the chocolate. Pour this mixture over the cooled crust and spread with an offset spatula until even.
7. Sprinkle chopped peanuts over the top for crunch and texture. Press lightly so they stick.
8. Finally, refrigerate for at least 3 hours, until fully set and firm to the touch. Slice into squares and serve chilled or slightly warmed.

For another quick set dessert, I also use the method in my 5-minute fudge post when I need to move fast.

Kitchen Tips (From My Kitchen)

1. Time-saver: Toast peanuts in a skillet while the crust bakes for extra aroma.
2. Common mistake + fix: If ganache looks separated, warm it gently over a simmering water bath and whisk until smooth.
3. Simple variation: Stir in a pinch of flaky sea salt or a dash of cinnamon for depth.

Serving Ideas

• Cut into small squares for a potluck dessert tray; garnish with a sprinkle of flaky sea salt.
• Serve slightly warmed with vanilla ice cream for a cozy weeknight treat.
• Pack into snack boxes for picnics or school lunches.
• Offer with strong coffee or an espresso at brunch.
• Try adding a drizzle of caramel for a holiday twist; pair with slices of apple on the side.

Storing & Leftovers

• Fridge: Store in an airtight container for up to 5 days.
• Freezer: Wrap tightly and freeze up to 1 month; thaw overnight in the fridge.
• Reheat: Warm briefly in the microwave (5–8 seconds) to keep marshmallows soft without melting the whole bar.

Leftover idea: Chop and fold into a bowl of plain yogurt or ice cream for instant crunch.

FAQs

Q: Can I make S’more Nut Bars ahead?
A: Yes — make them a day ahead and they’ll taste even better after the flavors meld.

Q: Can I substitute the peanuts?
A: Sure — use toasted almonds or pecans for a different texture and flavor.

Q: How do I know they’re done?
A: The crust should be lightly golden and the ganache firm to the touch after chilling. If it jiggles, give it more time.

Q: Can I freeze them?
A: Absolutely; freeze in a single layer first, then stack with parchment between for easy portions.

Final Thoughts

I make these S’more Nut Bars whenever I want a little campfire nostalgia without the smoke and fuss. They’re forgiving, shareable, and simple to tweak. Try them, and make them your own — change the nuts, add salt, or keep them exactly as I do.
