S’mores Brownies: Ingredients & Substitutions

Graham crackers. Use your favorite variety, or use gluten-free graham crackers to make this recipe gluten-free.
Semisweet chocolate. In the brownie layer, you can use discs or bars because it’s being melted. You can use dark chocolate or milk chocolate for a richer, sweeter flavor.
Salted butter. Unsalted butter works great as well.
Granulated sugar. Organic cane sugar works well too!
All-purpose flour. Use an all-purpose gluten-free baking flour to make these brownie bites gluten-free.
Marshmallows. Use mini marshmallows for the best result! If you only have large mallows, slice them in half.

How to Make Smores Brownies

Let’s walk through this recipe together, and don’t forget to watch the video.

It’s very important to line the baking dish with parchment paper and grease the sides. I trace the bottom of the baking dish on the paper then add “handles” to opposite sides for easy removal. The marshmallows make the smores brownies extra gooey and sticky so you want to do whatever you can to make removal easy!

Then, melt the chocolate and butter together until smooth and glossy – either in the microwave or on the stovetop over low heat. Then set the mixture aside to cool slightly.

Next, beat the eggs for 1 minute. Don’t skip this, as I say in every single one of my brownie recipes – beating the eggs well is what gives brownies their shiny top.

Then add the sugar and beat for an additional minute on high speed.

Then, beat in the melted butter/chocolate mixture and vanilla on medium speed.

Add the flour, salt and cocoa powder to the wet ingredients and beat until incorporated. The batter should be thick, not runny.

Stir in the chocolate chips and marshmallows until evenly distributed throughout the batter.

Once the batter is ready, arrange the 4 ½ full sheets of graham crackers in the bottom of the prepared baking dish. Then, carefully and evenly spread the batter over the top of the grahams.

Then, bake the smores brownies in a preheated oven for 25 minutes.

After 25 minutes, remove the brownies from oven and change the oven temperature to the “broil” setting. Evenly place the remaining 2 cups of mini marshmallows on top of the brownies.

Then, put the brownies back in the oven (set to broil) and broil for 30-60 seconds, until the marshmallows are lightly toasted. Watch the brownies carefully – this happens very fast.

Then let the smores brownies cool completely before cutting and serving.

Serve

Once the brownies are cooled, cut into 16 squares and serve at room temperature.

To get clean cuts, make sure the brownies are completely cooled and firm. Then dip a sharp knife in very hot water, dry it quickly with a towel, then make a cut. Then, wipe the knife off and repeat with each cut.

Store/Freeze

Store leftover s’mores brownies in an airtight container at room temperature for 2 days, in the refrigerator for 1 week, or in the freezer for up to 1 month. Thaw at room temperature, you can warm them in the microwave slightly to restore the gooey warm texture.

Smores Brownies Recipe FAQS

Can I double this recipe?

Yes absolutely, double the ingredients and bake the brownies in a 9×13″ glass baking dish.

Can I use a boxed brownie mix?

Ugh, I have not made brownies from a box in 20 years. They’re so easy to make homemade and so much better! But, you absolutely can use a boxed brownie mix if you’re short on time.

How do you keep marshmallows from burning on top?

Add the marshmallows in the last minute or two of baking and stand right in front of your oven with the light on for the 30 seconds it takes for them to brown.

Can I use marshmallow fluff instead of marshmallows?

Technically you can mix the fluff into the brownies and spread it on top and toast it instead of mini marshmallows if you prefer.
