What Ingredients You Will Need

This gooey cast iron loaded s’mores dip is built on simple, familiar ingredients that combine for maximum comfort and flavor without fuss.

• Mini marshmallows: about 3 cups (look for fresh, fluffy ones for best melting)
• Chocolate: 8 ounces of semi-sweet or milk chocolate chunks or chopped chocolate bars (I like using Ghirardelli for a smooth melt)
• Graham crackers: 1 sleeve, broken into pieces for dipping
• Unsalted butter: 2 tablespoons, melted (adds richness and helps with that toasty edge)
• Optional add-ins: chopped nuts like pecans or walnuts (for crunch), a pinch of sea salt (to balance sweetness), or a splash of vanilla extract (for depth)

All of these are pantry staples or easy to find in any grocery store. If you want a gluten-free version, swap the graham crackers for gluten-free crackers or sturdy cookies. For dairy-free, use vegan marshmallows and a dairy-free chocolate like Enjoy Life brand. The beauty of this recipe is how forgiving it is with swaps.

Equipment Needed

• Cast iron skillet: A 6- to 8-inch skillet works best for even heating and that signature crusty edge.
• Oven or broiler: For melting and toasting the marshmallows on top.
• Mixing bowl: To combine melted butter and chocolate if you prefer pre-melting.
• Spatula or spoon: For spreading the layers evenly in the skillet.
• Optional: a small baking sheet if you want to catch drips or move the skillet easily.

You don’t need fancy tools here. If you don’t have a cast iron skillet, an oven-safe ceramic dish or metal pie plate can work, but you’ll miss out on that toasty crust. I’ve tried enamel-coated cast iron too, and it still works great—just be mindful not to overheat. Keeping your cast iron well-seasoned makes cleanup easier and prevents sticking, which is a lifesaver with sticky marshmallow.

Preparation Method

1. Preheat your oven: to 375°F (190°C). This temperature helps melt the chocolate evenly while toasting marshmallows without burning them.
2. Melt the butter: In a small saucepan or microwave-safe bowl, melt 2 tablespoons of unsalted butter until just liquid. This adds richness and helps the chocolate melt smoothly.
3. Prepare the chocolate: Chop 8 ounces of your favorite chocolate bars into chunks (or use chips). Toss the chunks with the melted butter to coat them lightly—this helps the chocolate spread evenly in the skillet.
4. Layer chocolate in skillet: Pour the chocolate and butter mixture into your cast iron skillet, spreading it out in an even layer about 1/2 inch thick.
5. Add marshmallows: Generously pile 3 cups of mini marshmallows over the chocolate, covering the surface completely. For extra gooeyness, press some marshmallows slightly into the chocolate layer.
6. Bake: Place the skillet in the oven for about 8 to 10 minutes until the chocolate is melted and marshmallows start to puff and turn golden. Keep an eye on it—marshmallows toast quickly!
7. Optional broil step: For perfectly toasted tops, switch to broil for 1-2 minutes—but watch closely to avoid burning.
8. Serve: Remove from oven carefully (the skillet will be hot!). Serve warm with graham crackers broken into pieces for dipping right away.

Tip: If you want a little crunch, sprinkle chopped nuts or a pinch of sea salt on top before baking. It adds a nice contrast to all that gooey sweetness.

Cooking Tips & Techniques

One thing I learned the hard way is to watch the marshmallows like a hawk during baking. They can go from perfectly toasted to burnt in seconds—especially if you opt for the broil step. Use the oven light and keep the door slightly open to monitor progress.

Another tip: don’t skip coating the chocolate chunks with melted butter. It keeps the chocolate from seizing and makes the dip smoother. Also, use fresh mini marshmallows—they puff up and toast better than the stale, hard ones lurking in the back of your pantry.

For consistent results, preheat your cast iron skillet briefly in the oven before adding ingredients. This helps create that lovely crust without overcooking the marshmallows. And if you’re feeling fancy, adding a splash of vanilla extract into the melted butter can make the flavor pop.

Multitasking? While the dip bakes, prep your graham crackers and nuts for quick serving. Timing is everything because this dip is best enjoyed warm—once it cools, it starts firming up and loses that ooey-gooey magic.

Variations & Adaptations

• Peanut Butter S’mores Dip: Swirl 2 tablespoons of creamy peanut butter into the melted chocolate before topping with marshmallows. It adds a salty, nutty twist that’s irresistible.
• Berry S’mores Dip: Add a handful of fresh or frozen raspberries or strawberries on top before baking for a fruity contrast that cuts through the sweetness.
• Vegan/Dairy-Free Version: Use vegan marshmallows (available at specialty stores), dairy-free chocolate, and coconut oil instead of butter. The flavor changes slightly but stays delicious and inclusive.

If you want to try a different cooking method, you can assemble the dip in a slow cooker on low for about 1 hour, stirring halfway to melt everything smoothly. It’s less crispy on top but great for easy entertaining.

My personal favorite tweak is adding a pinch of espresso powder to the chocolate mix—it deepens the flavor, making it richer and less sweet. Believe me, it’s a subtle but game-changing touch.

Serving & Storage Suggestions

Serve this gooey cast iron loaded s’mores dip warm, straight from the oven, with plenty of graham crackers for dipping. If you want to dress things up for a party, add a small bowl of sliced fruit or a glass of cold milk alongside. Coffee or hot cocoa also pair wonderfully if you’re aiming for that ultimate cozy vibe.

Leftovers (if there are any!) can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, warm gently in the oven at 300°F (150°C) for 5-7 minutes or microwave in short bursts to avoid scorching. The texture will firm up once cooled, so it’s best enjoyed warm.

Fun fact: letting the dip sit for a few minutes after baking allows the flavors to meld and the chocolate to thicken slightly, making it easier to scoop but still wonderfully indulgent.

Nutritional Information & Benefits

This s’mores dip is definitely a treat, rich in sugars and fats from marshmallows, chocolate, and butter. A typical serving (about 1/4 cup dip plus crackers) contains roughly 250-300 calories, with around 15 grams of fat and 25 grams of sugar.

Key ingredients like dark chocolate (if used) can offer antioxidants and mood-lifting compounds, while nuts add protein and healthy fats if included. Graham crackers provide a bit of fiber but also add carbohydrates.

For those watching gluten or dairy, swapping ingredients as mentioned earlier makes this indulgence accessible. Just remember, it’s a dessert to enjoy occasionally, perfect for those cozy moments that call for a little sweetness.
