Decadent Smoked Smores Skillet Brownie Recipe with Toasted Marshmallows Tutorial

What started as a scramble to keep things going turned into this indulgent, smoky delight I now can’t stop making: the decadent smoked s’mores skillet brownie with toasted marshmallows.

Honestly, I wasn’t expecting much. Brownies and s’mores? Sure, classic combos, but smoked? That was a curveball.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and you can easily find them at any grocery store or swap for alternatives if needed.

• For the Brownie Base:
  • 1 cup (226g) unsalted butter, softened (I prefer Kerrygold for its creamy texture)
  • 1 1/4 cups (250g) granulated sugar
  • 3/4 cup (165g) packed light brown sugar (adds moisture and caramel notes)
  • 4 large eggs, room temperature
  • 1 tbsp pure vanilla extract
  • 1 cup (120g) all-purpose flour (can substitute with almond flour for gluten-free)
  • 3/4 cup (75g) unsweetened cocoa powder (I use Valrhona for a rich chocolate taste)
  • 1/2 tsp baking powder
  • 1/2 tsp salt
  • 1 cup (175g) semi-sweet chocolate chips (Nestle Toll House or Ghirardelli work great)
• For the S’mores Topping:
  • 1 1/2 cups mini marshmallows (or regular marshmallows cut into smaller pieces)
  • 1 cup graham cracker crumbs (about 8 full sheets crushed)
  • 2 tbsp unsalted butter, melted (to mix with graham crumbs)
• For the Smoking Element:
  • Wood chips or smoking pellets (applewood or hickory recommended)

If you can’t find mini marshmallows, just chop regular ones up — they toast beautifully and melt into that perfect gooey layer. For a dairy-free version, swap butter with coconut oil and use dairy-free chocolate chips. The graham cracker crumbs add that iconic crunch and honey flavor that makes s’mores special, but crushed digestive biscuits can stand in if needed.

Equipment Needed

• 10-inch cast iron skillet: The star of this recipe, giving those crispy edges and even heat distribution. I have a Lodge skillet that’s seen years of use and still goes strong.
• Mixing bowls: One large for wet ingredients, one for dry.
• Electric mixer or whisk: To beat the butter and sugars until fluffy.
• Measuring cups and spoons: Essential for accuracy, especially with baking powder and cocoa.
• Spatula: For folding in chocolate chips and scraping down the batter.
• Smoking gun (optional): Adds the smoky flavor without needing an outdoor fire. If you don’t have one, a quick grill smoke or smoked salt can provide a hint.
• Kitchen torch or broiler: To toast the marshmallows to that perfect golden brown finish.

If you don’t have a cast iron skillet, a heavy oven-safe pan will do, but the texture won’t be quite the same. For budget-friendly options, thrift stores or online marketplaces often have great deals on cast iron. I recommend seasoning your skillet regularly to keep it non-stick and ready for this dessert and many others.

Preparation Method

1. Preheat your oven to 350°F (175°C). Lightly grease your 10-inch cast iron skillet with butter or non-stick spray. This helps the brownie edges crisp up beautifully.
2. Cream the butter and sugars: In a large bowl, beat 1 cup softened unsalted butter with 1 1/4 cups granulated sugar and 3/4 cup light brown sugar until light and fluffy, about 3-4 minutes. This step is key for a tender crumb.
3. Add eggs and vanilla: Beat in 4 large eggs, one at a time, ensuring each is fully incorporated before adding the next. Stir in 1 tablespoon vanilla extract. The batter will look glossy and smooth.
4. Combine dry ingredients: In a separate bowl, sift together 1 cup all-purpose flour, 3/4 cup cocoa powder, 1/2 teaspoon baking powder, and 1/2 teaspoon salt.
5. Fold dry into wet: Gradually add the dry mixture into the wet ingredients. Use a spatula to fold gently until just combined — don’t overmix or you’ll lose that fudgy texture.
6. Stir in chocolate chips: Fold in 1 cup semi-sweet chocolate chips evenly throughout the batter for gooey pockets of melty chocolate.
7. Pour batter into skillet: Spread evenly with a spatula, smoothing the top. It should reach about 3/4 inch thickness.
8. Prepare the graham cracker topping: Mix 1 cup graham cracker crumbs with 2 tablespoons melted butter until crumbly but moist. Sprinkle this evenly over the brownie batter.
9. Bake: Place the skillet in the oven and bake for 30-35 minutes. The edges should be set and pulling away slightly, but the center remains soft. Insert a toothpick near the center — it should come out with moist crumbs, not wet batter.
10. Smoke the brownie: Once baked, remove the skillet from oven. Using a smoking gun, infuse the top of the brownie with smoke for about 1-2 minutes, covering the skillet with a lid or foil to trap the smoke. This step is what makes the dessert uniquely smoky without overpowering sweetness.
11. Add marshmallows: Immediately sprinkle 1 1/2 cups mini marshmallows over the top, covering the graham cracker layer. Use a kitchen torch or place under the broiler for 1-2 minutes to toast until golden brown and puffed. Watch carefully — marshmallows burn fast!
12. Serve warm: Let the skillet cool for about 10 minutes (if you can wait!). Grab a spoon and dig in straight from the skillet for that rustic, cozy feel.

Pro tip: If you don’t have a smoking gun, a few drops of smoked sea salt in the batter can add subtle smoky notes. Also, keep an eye on the marshmallows while toasting — I once got distracted by a phone call and ended up with a mini marshmallow bonfire (lesson learned!).

Cooking Tips & Techniques

Getting that perfect balance between fudgy brownie and toasted marshmallow topping can be a little tricky, but here are some tips I picked up along the way:

• Use room temperature eggs: They blend more evenly with the batter, helping achieve a smooth texture.
• Don’t overmix dry ingredients: Folding gently keeps the brownie tender rather than cakey.
• Watch your bake time: Slightly underbaking (30 minutes) gives you that gooey center, while overbaking makes the brownie dry. I always set a timer and check early.
• Smoking technique: If using a smoking gun, trap the smoke with foil to let it seep in better. For first-timers, practice smoking with just a small amount — it’s easy to overwhelm the dessert.
• Toasting marshmallows: Use a kitchen torch for precise control. If broiling, stay close and open the oven door frequently to avoid burning.
• Cast iron skillet care: Season your skillet regularly to prevent sticking and rust. I keep mine lightly oiled after each use.
• Multitasking: While the brownie bakes, prep your graham cracker topping and get your smoking setup ready — makes the process smoother.

I’ve burned marshmallows more times than I’d admit, and once forgot to smoke the brownie before adding marshmallows — it was still tasty but missed that smoky allure. Don’t be discouraged by small slip-ups; every attempt brings you closer to your perfect skillet brownie.

Variations & Adaptations

This decadent smoked s’mores skillet brownie is flexible and fun to tweak for different tastes and dietary needs:

• Nutty Twist: Add 1/2 cup chopped toasted pecans or walnuts into the batter for crunch and depth.
• Vegan Option: Use flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg), vegan butter, and dairy-free chocolate chips. Swap marshmallows for vegan versions or toasted coconut flakes.
• Seasonal Fruit Boost: Sprinkle fresh or frozen raspberries or cherries into the batter before baking for a tart contrast.
• Different Smoking Flavors: Experiment with cherry wood or mesquite chips for unique smoky profiles.
• Alternative Cooking Method: You can bake this in a 9×9 inch baking pan if you don’t have a skillet, but the edges won’t crisp up as much.

Once, I tried adding a swirl of peanut butter into the batter before baking — it added a creamy, salty layer that paired wonderfully with the smoky chocolate. Honestly, that batch disappeared faster than any other!

Serving & Storage Suggestions

Serve this smoked s’mores skillet brownie warm, straight from the skillet, with a big spoon or spatula to scoop out gooey layers. It pairs beautifully with a scoop of vanilla ice cream or a drizzle of caramel sauce for extra indulgence.

For beverages, think rich coffee, a bold red wine, or even a creamy hot chocolate to complement the smoky-sweet notes.

To store leftovers, cover the skillet tightly with plastic wrap or transfer the brownies to an airtight container. Refrigerate for up to 3 days. Reheat gently in the microwave for 20-30 seconds or in a low oven (300°F/150°C) until warm and soft again.

Flavors actually deepen after a day as the smoke settles and melds with the chocolate, so if you can wait, it’s worth it. Just re-toast marshmallows before serving if you want that fresh-toasted effect.
