Easy S'mores Brownies Ingredients

Honey Graham Crackers
Salted Butter
Unsweetened Cocoa Powder
Sugar
Eggs
Pure Vanilla Extract
Unbleached All Purpose Flour
Milk Chocolate Chips
Mini Marshmallows
Hershey's Milk Chocolate Bar

Substitution Suggestions:

Salted Butter: You can use unsalted butter, but add ½ teaspoon of salt to the brownie batter.
Homemade Brownies: to make this recipe even easier, you can use a box mix of brownies for a 9x13 baking dish. However, in my opinion the homemade brownie tastes so much better!
Milk Chocolate Chips: You can use your favorite chocolate chip if you prefer. I like to use milk chocolate so the flavor of classic s'mores really stands out.
Mini Marshmallows: Large marshmallows did not work well with this recipe. However, you can use marshmallow fluff it's just a little bit messier when you spread it over the brownies but just as tasty!

How to Make S'mores Brownies

Preheat the oven to 350°F and grease a 9x13 baking dish with nonstick cooking spray or you can line the baking dish with parchment paper and grease the paper.
Layer 7 ¼ graham cracker sheets in the bottom of the prepared pan. Add the remaining graham crackers to a plastic bag and roughly crush them or break them up into small pieces. Break the Hershey's bar into 12 pieces.
Melt the butter in a small saucepan over low heat on the stove or in a large glass mixing bowl in the microwave. I almost always use the microwave.
In a large mixing bowl, whisk together the melted butter and unsweetened cocoa powder until smooth.

Add the white sugar and whisk until combined.
Next, add the eggs and pure vanilla extract. Whisk until smooth and airy.
Stir in the all purpose flour with a spatula.
Now, fold in ¾ cup of the milk chocolate chips.

Add the brownie batter on top of the graham cracker layer in the baking dish and gently spread it to the edges. Pro tip: an offset spatula works great for this.
Bake the brownies for 30-32 minutes until the center is not jiggly and a toothpick inserted in the center comes out with a little bit of batter on it. The brownies will be a little underdone at this point.
Sprinkle the marshmallows in a single layer on top of the brownies. Then sprinkle the remaining milk chocolate chips and graham cracker crumbs. Lastly, place the Hershey's bar pieces on top of everything.

Marshmallows and toppings added to the brownies.

Place brownies back in the oven and bake for 6-7 minutes until the marshmallows have puffed up and started to turn a light golden brown.
Let brownies cool for at least 30 minutes before slicing and serving.

How to Store S'mores Brownies From Scratch

Storing: These S'mores Brownies store best at room temperature tightly covered. They'll last up to 5 days, but I'm assuming they'll be gone the day you make them!

Freezing: These brownies freeze best when they are individually wrapped in plastic wrap and then placed in a freezer safe air tight container or zip top bag. Freeze up to 4 months.

Thawing: Remove brownie from freezer, unwrap and let thaw on the counter for at least 30 minutes.

Tips for the Best S'mores Brownies

For easy removal, line the baking dish with parchment paper. This will allow you to remove the entire pan of brownies all at once and then slice easily.
For best results don't overbake the brownies, you want them to be just slightly underdone before adding the marshmallows.
If you want a more toasted marshmallow, you can broil the marshmallows instead of baking them. Set your oven to broil and broil for 2-3 minutes, watch closely so you don't burn them.
The best way to cut the brownies into slices is to rub some nonstick spray on a serrated knife and make one slice. Then clean the knife and repeat. This will help make clean cuts when slicing the brownies.
