What Makes This Recipe So Good
This isn’t just hot chocolate—it’s a full s’mores experience, minus sticky fingers and rogue sparks. The secret? Real chopped chocolate and cocoa powder for layered richness, not just cocoa mix.
A quick toasted marshmallow crown brings that campfire aroma, and a graham cracker rim adds crunch in every sip.
We balance sweetness with a pinch of espresso powder (no, it won’t taste like coffee), and a touch of smoked salt that fakes a fire pit in the best way. It’s decadent but not cloying, nostalgic but grown-up. Translation: you’ll want seconds.
Ingredients
- 2 cups whole milk (or a mix of milk and half-and-half for extra richness)
- 1/2 cup heavy cream (optional but glorious)
- 3 ounces semi-sweet chocolate, finely chopped (60–70% cacao is ideal)
- 2 tablespoons Dutch-process cocoa powder
- 2–3 tablespoons light brown sugar (adjust to taste)
- 1 teaspoon vanilla extract
- 1/4 teaspoon espresso powder (optional, for depth)
- 1/8 teaspoon smoked sea salt (or regular sea salt)
- 1 tablespoon unsalted butter (for a silky finish)
- Large marshmallows (4–6, depending on servings; or a handful of minis)
- Graham crackers, crushed (about 1/2 cup for rimming)
- 2 teaspoons honey or maple syrup (to help the rim stick)
- Optional garnishes: chocolate shavings, pinch of cinnamon, drizzle of caramel, or a dusting of cocoa
How to Make It – Instructions
- Prep the graham rim: Crush graham crackers into fine crumbs.
Swipe a thin ring of honey or maple around the top of your mugs. Dip and twist the rim in the crumbs to coat. Set aside.
- Warm the base: In a medium saucepan, add milk and heavy cream.
Heat over medium-low until steaming, not boiling. If it bubbles, you went too hard—turn it down.
- Whisk in the dry team: Sift or whisk together cocoa powder, brown sugar, espresso powder, and salt. Sprinkle into the warm milk while whisking constantly to avoid cocoa clumps.
- Melt the chocolate: Add the chopped chocolate and whisk slowly until fully melted and glossy.
Keep it low and gentle. This is not a rolling boil situation.
- Finish and balance: Stir in vanilla and butter. Taste and adjust sweetness or salt.
If it’s too thick, add a splash of milk; too thin, simmer a minute longer.
- Toast the marshmallows: Place marshmallows on a foil-lined baking sheet and broil on high for 20–40 seconds until caramelized and blistered. Watch like a hawk. Alternatively, use a kitchen torch and toast until golden.
- Assemble: Pour hot chocolate into graham-rimmed mugs.
Top with toasted marshmallows. Add chocolate shavings or a tiny cinnamon dusting if you’re feeling extra.
- Serve immediately: The marshmallow top is at peak gooey perfection for about 3 minutes. Don’t dilly-dally.
Keeping It Fresh
- Storage: Refrigerate leftover hot chocolate (without marshmallows) in a sealed jar for up to 3 days.
- Reheat: Warm gently on the stovetop over low heat, whisking.
Add a splash of milk to loosen if it thickened in the fridge.
- Make-ahead: Mix the dry ingredients (cocoa, sugar, espresso, salt) as a jarred “mix” and store for a month. Add milk, cream, and chocolate when ready.
- Marshmallows: Toast fresh every time. Pre-toasted marshmallows taste like yesterday’s campfire—hard pass.
Health Benefits
Yes, it’s indulgent, but there are some wins here. Cocoa is rich in flavanols, which support blood flow and may help mood—chocolate cheer is real.
A little dark chocolate brings antioxidants and can satisfy cravings faster than overly sweet mixes, which means you might drink less overall.
Using whole milk adds protein and calcium; swapping part of it for oat or almond milk can reduce saturated fat. The pinch of salt enhances flavor so you don’t need to pile on sugar. Balance, not deprivation—that’s the game.
What Not to Do
- Don’t boil the milk. It can scorch and separate, and your chocolate will turn grainy.
Low and slow wins.
- Don’t skip the real chocolate. Only cocoa powder = flat flavor. The combo is the magic.
- Don’t over-sweeten early. Add sugar gradually, then taste after the chocolate melts. It often needs less than you think.
- Don’t walk away from the broiler. Marshmallows go from golden to “alarmingly on fire” in seconds.
FYI.
- Don’t rim too thick. A chunky graham cement layer will crumble into your drink like edible gravel. Light coat is best.
Alternatives
- Dairy-free: Use a 50/50 blend of oat milk and coconut milk for body. Skip butter or swap with vegan butter.
Choose dairy-free chocolate.
- Refined sugar-light: Use maple syrup or coconut sugar; start with less and adjust.
- No torch/broiler: Use mini marshmallows and stir them in; they’ll melt into a marshmallow cap. Not as dramatic, still delicious.
- Spice it up: Add a pinch of cinnamon and nutmeg for fall vibes. For a Mexican hot chocolate riff, include a whisper of cayenne.
- Smoky shortcut: A tiny drop of liquid smoke can mimic campfire, but be careful—more than a drop turns it into BBQ cocoa.
IMO, smoked salt is safer.
- Graham swap: Use crushed Biscoff, digestive biscuits, or a gluten-free graham alternative.
- Adults-only: Add 1 ounce of bourbon, dark rum, or coffee liqueur per mug after pouring.
FAQ
Can I use chocolate chips instead of chopped chocolate?
Yes, but choose higher-quality chips labeled for baking; they melt better. Chips have stabilizers, so the texture won’t be quite as silky as chopped bars, but it’s still solid.
How do I keep the cocoa from clumping?
Whisk dry ingredients together first, then sprinkle them in gradually while whisking the warm milk. You can also make a quick paste with a few tablespoons of warm milk, then whisk that into the pot.
What if I don’t have a broiler or torch?
Place marshmallows on skewers and carefully toast over a gas stove flame, rotating constantly.
No flame? Stir in minis and top with a graham crumble for the s’mores effect.
Can I make this for a crowd?
Absolutely. Multiply everything by 3 or 4, keep warm in a slow cooker on low, and toast marshmallows in batches.
Set up a garnish station and let people build their own.
Is it too sweet for kids?
Not by default. Start with 2 tablespoons of sugar and taste. The graham rim and marshmallow add sweetness, so you likely won’t need extra.
Can I prepare the mugs ahead of time?
Yes, rim them with honey and graham up to 2 hours ahead.
Store at room temperature. Don’t refrigerate—humidity will make the crumbs sad and soggy.
What’s the best cocoa to use?
Dutch-process cocoa gives a smoother, more chocolatey flavor and deeper color. Natural cocoa works too; you may want a pinch more sugar to balance its sharper edge.
How do I fix grainy hot chocolate?
Remove from heat and whisk in a splash of warm milk.
If it’s still grainy, blend with an immersion blender for 10–15 seconds to re-emulsify. Avoid boiling next time.
