S’mores Dip on the Grill
This cast iron s’mores dip is one of those backyard desserts that looks like you worked way harder than you actually did. You get melted chocolate, toasted marshmallows, crispy graham crackers, and that classic campfire flavor without having to build a fire, sharpen sticks, or watch half the marshmallows fall into the flames.
It’s the perfect dessert for a BBQ night because it is fast, fun, and built for sharing. Set the skillet right in the middle of the table with a pile of graham crackers, pretzels, strawberries, or cookies, and watch everybody dive in like they have not eaten all day.The best part is how easy it is. Butter a cast iron skillet, load it with chocolate, cover it with marshmallows, and let the grill, smoker, or oven do the work. The chocolate melts underneath, the marshmallows toast on top, and the whole thing turns into a warm, gooey dessert dip that tastes like summer.
You can make this on a gas grill, charcoal grill, pellet grill, smoker, or right in the oven. If you are already cooking outside, this is a perfect dessert to throw on after the burgers, ribs, chicken, or hot dogs are done.

What Makes This S’mores Dip So Good
The magic is the contrast. You get warm melted chocolate underneath, golden toasted marshmallows on top, and crunchy graham crackers for dipping.
A little butter in the skillet helps prevent sticking and adds richness. Milk chocolate gives you that classic s’mores flavor, while a handful of semi-sweet chocolate chips keeps it from becoming too sweet.
The cast iron matters too. It holds heat well, looks great for serving, and helps keep the dip warm after it comes off the grill.
Best Chocolate for Cast Iron S’mores Dip
Milk chocolate gives you the most classic s’mores flavor. Chocolate bars work great because they melt into smooth layers, but chocolate chips are easier and cheaper.
Best options:
-Milk chocolate chips
-Semi-sweet chocolate chips
-Chopped milk chocolate bars
-Hershey-style chocolate bars
-Dark chocolate chips for a less sweet version
-Peanut butter chips mixed with chocolate
For the best balance, use mostly milk chocolate with a little semi-sweet chocolate mixed in.
Best Dippers for S’mores Dip
Graham crackers are the classic choice, but you can build a whole dessert board around this skillet.
Use:
-Graham crackers
-Pretzels
-Vanilla wafers
-Strawberries
-Banana slices
-Apple slices
-Butter cookies
-Shortbread cookies
-Animal crackers
-Chocolate chip cookies
The salty pretzels are especially good because they cut through the sweetness.
How to Make Cast Iron S’mores Dip on the Grill
Set your grill or smoker to 350°F. You want medium heat, not a roaring fire. If you are using charcoal, set it up for indirect heat so the bottom of the skillet does not scorch.
Grease the cast iron skillet with butter, then add the chocolate in an even layer. Top it with marshmallows, trying to cover most of the chocolate without packing them in too tightly.
Place the skillet on the grill, close the lid, and cook until the chocolate is melted and the marshmallows are puffed and golden. This usually takes 8 to 12 minutes, depending on your grill.
Let it sit for a few minutes before serving. That little rest keeps the chocolate from being lava-hot and helps the dip thicken just enough for better scooping.
Smoker Method
For a smoked version, run your smoker at 350°F with a mild wood like cherry, apple, or pecan
.Desserts pick up smoke quickly, so keep the smoke light. You want a subtle backyard flavor, not a chocolate campfire accident.
Smoke the skillet uncovered for 8 to 12 minutes, or until the chocolate is melted and the marshmallows are toasted.
Oven Method
Preheat your oven to 350°F.Build the dip in the cast iron skillet the same way, then bake for 8 to 12 minutes until the chocolate is melted and the marshmallows are puffed.
For extra color, you can broil it for 30 to 60 seconds at the end, but watch it closely. Marshmallows go from golden to burnt real quick.
Tips for the Best Cast Iron S’mores Dip
Use indirect heat if cooking on charcoal.
Do not crank the grill too hot or the chocolate can scorch before the marshmallows toast.
Grease the skillet lightly with butter.
Use a mix of milk chocolate and semi-sweet chocolate for better balance.
Let the dip rest for a few minutes before serving.
Serve it warm while the chocolate is still soft.
Keep extra graham crackers nearby. You’ll need more than you think.
Easy Flavor Variations
Peanut Butter S’mores Dip: Add peanut butter chips or spoon small dollops of peanut butter between the chocolate pieces.
Salted Caramel S’mores Dip: Drizzle caramel over the chocolate before adding marshmallows.
Cookies and Cream S’mores Dip: Add crushed chocolate sandwich cookies under the marshmallows.
Spicy S’mores Dip: Add a tiny pinch of cayenne to the chocolate for a sweet heat version.
Dark Chocolate S’mores Dip: Use dark chocolate chips for a richer, less sweet dessert.
Banana S’mores Dip: Add thin banana slices over the chocolate before topping with marshmallows.
