This S’mores Brownie Skillet is warm, fudgy, and gooey, and is a great treat for everyone! A brownie base, topped with a crumbly graham cracker layer, and perfectly golden, toasted marshmallows on top, it’s your favorite backyard treat without the campfire.
About this Brownie Skillet
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. Altogether, delicious.
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 skillet right on the counter and taking a bite whenever I get a craving. It tastes great cold, too!

Recipe Ingredients
- Graham Cracker: The foundation of a s’more will become a delicious, crunchy topping for this brownie skillet.
- Marshmallows: The mini ones work best for this recipe. Keep a close eye on them under the broiler so they don’t burn!
- Greek Yogurt: I used Oikos Triple Zero Vanilla. This makes our brownies rich and moist.
- Cocoa Powder: For the best chocolately brownies. Hershey’s is my favorite. And for a super rich chocolate flavor, use the Special Dark variety.
- Flour: The base of our brownies for structure. A baking staple to help bind our all of the ingredients together. I used all purpose and have not tried any substitutes.

How to Make This Recipe
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. Next, beat in brown sugar and white sugar.
3. Fold in cocoa powder, all purpose flour, salt, and baking powder.
4. After the batter is thoroughly mixed, fold in chocolate chips.
5. Then, pour batter into your well greased skillet. 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.
6. Bake for 18-20 minutes or until the middle is cooked. 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!
Expert Tips
For 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 to create a fudgy yet fluffy brownie.
Recipe FAQs
If you have leftovers, just add tinfoil over the top and it can be stored on the counter for 3 days.
Yes! And that’s exactly what we do in this recipe. This brownie skillet doesn’t have any oil or butter, but the yogurt keeps them rich and moist. If you swap out oil instead, note you’ll need about double the amount of the Greek yogurt used (i.e. this recipe calls for 1/4 cup of yogurt so you will need 1/2 cup oil).
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.
Yes! If you don’t have a skillet, you can cook these in a square baking dish and may need ~5 minutes extra of bake time since the cast iron retains heat better it will cook faster.
