  • 1 box (18–20 oz) brownie mix
  • 2 large eggs
  • 1/3 cup vegetable oil
  • 1 tablespoon water
  • 1/2 cup semi-sweet chocolate chips
  • 1/2 cup crushed graham crackers (about 4 sheets)
  • For the Marshmallow Top:
  • 18 large marshmallows (one per cookie)
  • 1/4 cup mini chocolate chips (optional, for garnish)
  • 1/4 cup additional crushed graham crackers (optional, for garnish)

Instructions

Step 1: Prepare Your Workspace
Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper.
Step 2: Mix the Dough
In a large bowl, combine the brownie mix, eggs, oil, and water. Mix until just combined and no dry streaks remain.
Step 3: Add Mix-Ins
Gently fold in the chocolate chips and crushed graham crackers.
Step 4: Shape the Cookies
Scoop heaping tablespoons of dough onto the prepared baking sheets, spacing about 2 inches apart (about 18 cookies).
Step 5: Initial Bake
Bake for 8–9 minutes, until cookies are just set but still soft in the center.
Step 6: Add Marshmallows
Remove from oven and immediately press one large marshmallow onto the center of each cookie.
Step 7: Melt the Marshmallows
Return cookies to the oven for 1–2 minutes, until marshmallows are puffed and just starting to melt.
Step 8: Toast (Optional)
For a toasted top, broil for 30 seconds, watching closely, until marshmallows turn golden brown.
Step 9: Garnish
Remove cookies from oven. Immediately sprinkle with mini chocolate chips and extra graham cracker crumbs, if using.
Step 10: Cool
Cool on baking sheets for 5 minutes, then transfer to a wire rack to cool completely.

Zusatztipps für die Zubereitung

The key to perfect s'mores cookies is timing. Don't overbake the initial cookies—they should look slightly underdone when you add the marshmallows, as they'll continue to set during the second bake. When toasting marshmallows under the broiler, stay close and watch carefully; they can go from golden to burnt in seconds. If you prefer more control, a kitchen torch allows you to toast each marshmallow individually to your desired level of caramelization. For the graham crackers, pulse them in a food processor or place them in a sealed bag and crush with a rolling pin until you have a mix of fine crumbs and small chunks—this creates the best texture contrast.

Varianten und Anpassungen

These cookies are wonderfully adaptable to your preferences and dietary needs. Swap semi-sweet chocolate chips for dark chocolate for a more sophisticated flavor, or use milk chocolate for extra sweetness. Add a pinch of cinnamon or espresso powder to the dough to enhance the chocolate notes. For a gluten-free version, use a gluten-free brownie mix and certified gluten-free graham crackers. You can also experiment with flavored marshmallows like vanilla bean or strawberry for a fun twist. If you want an extra-decadent treat, drizzle cooled cookies with melted chocolate or add a sprinkle of sea salt on top of the marshmallows.

Serviervorschläge

These s'mores brownie cookies are delicious on their own, but they're even better when paired thoughtfully. Serve them warm with a cold glass of milk for the ultimate comfort food experience, or alongside a scoop of vanilla ice cream for an indulgent dessert. They make a fantastic addition to dessert platters at parties, barbecues, or holiday gatherings. For a campfire-themed party, arrange them on a rustic wooden board with extra graham crackers, chocolate bars, and marshmallows. They also pack well for picnics, lunchboxes, or care packages—just layer them between parchment paper in an airtight container. Store leftovers at room temperature for up to three days, though they're best enjoyed within the first day or two when the marshmallows are still soft and the cookies maintain their chewy texture.

Recipe FAQs

Can I use dark chocolate chips instead of semi-sweet?

Yes, dark chocolate chips add a richer flavor and pair well with the sweetness of the marshmallows and graham crackers.

How do I achieve the toasted marshmallow topping?

After baking the cookies, place a marshmallow on each and return to the oven briefly. For a golden finish, broil briefly or use a kitchen torch carefully.

Can I prepare these ahead of time?

You can prepare the dough in advance and bake when ready. Store finished cookies in an airtight container up to 3 days to maintain freshness.

What if I don’t have graham crackers?

Crushed digestive biscuits or similar cookies can be used to add texture and a mild sweetness comparable to graham crackers.

Are these suitable for vegetarians?

Yes, the ingredients used are vegetarian-friendly; just ensure chocolate and marshmallows fit your dietary preferences.
