Equipment You’ll Need

You won’t need anything fancy here – just a few basics to whip up these skillet s’mores brownies:

10-inch cast-iron skillet – the hero of this recipe (don’t worry, I’ll tell you how to adapt if you don’t have one)

Mixing bowls – one big one for dry ingredients, another for wet
Wooden spoon – my favorite tool for perfect brownie batter
Measuring cups & spoons – accuracy matters with baking!
Oven mitts – that skillet gets hot, trust me!

That’s it! No stand mixer or fancy gadgets required for this simple, delicious dessert.

How to Make Skillet S’mores Brownie

Okay, let’s get to the fun part – making this gooey masterpiece! I promise it’s easier than you think, and the smell filling your kitchen will have everyone asking “Is it ready yet?” before the timer even dings.

Preparing the Batter

First things first – preheat that oven to 350°F (175°C). While it’s heating up, grab your trusty 10-inch cast-iron skillet and give it a quick grease. I like to use butter for extra flavor, but cooking spray works too.

Now for the dry ingredients: whisk together the flour, sugar, cocoa powder, salt and baking powder in a big bowl. Don’t skip the whisking – we want all those dry friends to get to know each other really well. In another bowl, mix the melted butter, eggs and vanilla until they’re best buddies.

Here’s the important part: gently stir the wet ingredients into the dry ones. I mean it – be gentle! Overmixing makes tough brownies, and we want fudgy perfection. When it’s almost combined, fold in those chocolate chips – I always sneak a few extra because why not?

Baking and Adding Toppings

Pour your beautiful batter into the prepared skillet and smooth it out. Pop it in the oven for 20 minutes – this gives the brownie base time to set up before we add our toppings.

Now the magic happens! Pull the skillet out (careful, it’s hot!) and sprinkle on the marshmallows and crushed graham crackers. I like to press the marshmallows in slightly so they don’t roll off. Back in the oven it goes for about 5 more minutes, just until those marshmallows turn golden brown and puffy.

Pro tip: Watch it like a hawk during these last few minutes – marshmallows go from perfect to burnt in no time! Let it cool for about 10 minutes before diving in (if you can wait that long). The smell will test your willpower, I promise.

Tips for the Perfect Skillet S’mores Brownie

After making this recipe more times than I can count (quality control, you know?), I’ve picked up some foolproof tricks:

Room temp eggs are key – they blend smoother into the batter for that perfect fudgy texture

Set a timer! Overbaking is the enemy of gooey brownies – pull it when the edges look set but center still jiggles slightly
Let it rest 10 minutes before slicing (I know, torture!) – this helps the marshmallows set so they don’t ooze everywhere
Broil for 30 seconds if your marshmallows need extra browning – just don’t walk away!

Follow these simple tips and you’ll get that perfect campfire-inspired dessert every single time.

Ingredient Substitutions

Don’t have exactly what the recipe calls for? No worries – I’ve tested plenty of swaps that still deliver delicious results! For gluten-free, use a 1:1 gluten-free flour blend (though the texture will be slightly more crumbly). Dairy-free butter works great if needed – just know it might change the richness a tiny bit. Dark chocolate chips instead of semi-sweet will give a more intense chocolate flavor (my personal favorite twist). And if you’re out of mini marshmallows, large ones chopped up work in a pinch – they’ll just take longer to melt.

Serving Suggestions

Oh my goodness – you’ve got options with this Skillet S’mores Brownie! My absolute favorite way is still warm from the oven with a scoop of vanilla ice cream melting into all those gooey marshmallow pockets. For a lighter touch, fresh whipped cream adds the perfect contrast to the rich chocolate. And here’s a secret: it’s incredible for breakfast too (don’t judge – those graham crackers totally count as cereal!).

Storing and Reheating Skillet S’mores Brownie

Now, I know what you’re thinking – “Like there will be leftovers!” But just in case, here’s how to keep that gooey goodness tasting fresh. At room temperature, cover the skillet tightly with foil or transfer slices to an airtight container – they’ll stay perfect for about 2 days. If you need longer, refrigerate for up to 5 days (though the marshmallows might get a bit sticky). To reheat, pop individual slices in a 300°F oven for 5-10 minutes until warm – microwaving makes the marshmallows rubbery. Pro tip: Sprinkle fresh graham cracker crumbs on top after reheating for that just-baked crunch!

Skillet S’mores Brownie FAQs

I get asked these questions ALL the time about this recipe, so let me save you some trouble with my hard-earned answers:

Can I use a regular baking pan if I don’t have a cast-iron skillet?
Absolutely! A 9×9 inch square pan works great. Just keep an eye on baking time – it might need a few extra minutes since the depth is different. The edges won’t get quite as crispy though (that’s the skillet magic!).

How do I prevent burnt marshmallows?
Watch like a hawk during those last 5 minutes! If they’re browning too fast, tent some foil over the top. I also find positioning the rack in the middle of the oven (not too close to the top heating element) helps a ton.

Why did my marshmallows melt completely into the brownie?
This happens if you add them too early. That’s why we bake the brownie base first – the extra 5 minutes at the end is just enough time for perfect golden puffs without disappearing acts!

Can I make these ahead for a party?
For best texture, bake them the same day. But you can mix the dry ingredients the night before to save time. Just add wet ingredients right before baking.

Nutritional Information

Just so you know, these numbers are ballpark estimates – your exact nutrition will depend on the specific brands and ingredients you use. This rich dessert is definitely an occasional treat (though I won’t judge if you sneak an extra bite!). Remember, we’re talking about a skillet full of chocolate, marshmallows, and graham crackers here – it’s meant to be indulgent and delicious, not diet food!
