Ooey, gooey, chocolatey s'mores brownie goodness

S’mores brownies in a cast iron skillet take me right back to roasting ‘mallows over the campfire. I love feeling the warmth of the fire on my face, smelling that sweet, woody smell, and taking a big old bite of an ooey gooey toasted marshmallow with melty chocolate and crunchy graham cracker.

Growing up, s’mores pop tarts used to be my favorite. And now, I love to create s’mores inspired recipes.

This S'mores Brownie Skillet is warm, fudgy, and gooey, and is a great treat for everyone! Toasting marshmallows under the broiler may not produce the same smokey flavor as a campfire, but they'll still turn a gorgeous golden brown—and they taste amazing with chocolate brownies!

I love leaving this s'mores brownie skillet right on the counter and taking a bite whenever I get a craving. It tastes great cold, too!

S'mores brownie skillet ingredients

Graham Cracker: The foundation of a smore will become a delicious, crunchy topping for this brownie skillet.

Marshmallows: Fluffy and gooey and so sweet! I love incorporating marshmallows into dessert.

Egg: To help bind our brownie ingredients together.

Greek Yogurt: I used Oikos Triple Zero Vanilla.

Vanilla Extract: A little vanilla flavor complements chocolate so well.

Nut Milk: Use your favorite here. Oat, almond, cashew, etc. You could also use dairy milk.

Light Brown Sugar: An important ingredient to add sweetness to our brownies.

White Sugar: More sweetness!

Cocoa Powder: For the best chocolately brownies.

All Purpose Flour: Another baking staple to help bind our brownie ingredients together.

Salt: One of my favorite ways to add more flavor dimension to chocolate.

Baking Powder: Will help our brownies rise and become fluffy!

Chocolate Chips: For more chocolate in each bite. I love to use the mini ones.

Butter, Grease, or Oil: Use what you have on hand to help prevent the brownie skillet from sticking.

Equipment required

To make this Smores Brownie Skillet, you'll need an 8 inch cast iron skillet, hand mixer, mixing bowl, a microwave safe bowl, rubber spatula, and measuring cups and spoons.

How to make this oven lovin' S'mores Brownie Skillet

1. Preheat oven to 350°F. Grease your skillet using butter or oil to keep the brownie from sticking.
2. In a mixing bowl, beat egg, Greek yogurt, nut milk, and vanilla extract until combined. 
3. Next, beat in brown sugar and white sugar.
4. Fold in cocoa powder, all purpose flour, salt, and baking powder.
5. After the batter is thoroughly mixed, fold in chocolate chips.
6. Then, pour batter into your well greased skillet. 
7. In a microwave safe bowl, crumble 2 sheets of honey graham crackers. Place a tablespoon of butter in the bowl and microwave for 30 seconds. Use a fork to combine crackers and butter. Sprinkle over uncooked brownie.
8. Bake for 18-20 minutes or until the middle is cooked. 
9. Once the brownie is done cooking, turn off the oven and turn on the broiler. Add marshmallows on top of your cooked brownie and place on the top rack of the broiler. Broil for 2-4 minutes or until marshmallows are a golden brown. Be sure to watch closely as they can burn easily!

How to get the fudgiest brownies

The key to the fudgiest brownies lies in the way you construct your batter. Baking is so delicate, and the amount of ingredients and how you incorporate them makes a huge difference in taste and texture.

To make a fudgy brownie batter, it’s important to beat the wet ingredients before you beat in the sugars. Once the sugar and wet ingredients are thoroughly incorporated, you then need to fold in the dry ingredients. The dry ingredients will absorb the sugar and wet ingredients.

If you beat the dry ingredients with the wet, the batter can become liquidly, which will prevent the brownies from rising and becoming fudgy and fluffy.

Questions & answers

How should I store this S'mores Brownie Skillet?
Store at room temperature or in the fridge.

Why do you use Greek yogurt?
I wanted a lighter version of a brownie without compromising on the delicious, ooey gooey taste and texture.

Can I use a different flour?
I haven't tested this recipe with a different flour. If you do choose to use one, make sure to adjust your ratios and note that you may have a different texture. Not all flours bake the same!

Can I freeze this brownie skillet?
I would not recommend freezing these brownies. They store great in the fridge. After the marshmallows heat and cool, they get incredibly sticky. I like to just leave the brownies in the skillet until they’re completely gone. This makes cleaning and storage easier.

What if I don't like marshmallows?
That's okay! If you are looking for an alternative topping, I think caramel or chocolate sauce, chopped nuts, or ice cream would be delicious.

Can I bake this in a brownie pan instead?
Though I haven’t tested that, I’m sure you’d get the same delicious brownies. Baking times may vary though, so be sure to check frequently.

What's the best way to clean a cast iron skillet?
You don't want to put a cast iron skillet in the dishwasher or use steel wool or soap. This will strip the seasoning. You don't want to soak it either, or it could rust. To remove stuck on food, you have a few options. Use a sponge or stiff brush or boil water in the skillet. You could also mix coarse salt and water to create a paste and rub it on the stuck on food. Dry your skillet completely with a towel and put on a light coat of oil or shortening. Then, store in a dry place.
