MARSHMALLOW BROWNIE INGREDIENTS
Be sure to see the recipe card below for full ingredients & instructions.
The S’mores flavor was originally made famous by the Boy Scouts and Girl Scouts of america as a campfire treat that is so delicious that everyone wants “some more.” The classic flavors of toasted marshmallow, melted chocolate, and buttery graham cracker are a match made in heaven. We cannot get enough of the combo and these brownies land fairly high at the top of our favorites.
- Box of Brownie Mix: Plus all of the ingredients called for on the box.
- Mini Marshmallows: You could always use large marshmallows. Just cut them into 1/4’s before adding to the top of your brownies.
- Graham Crackers: OR Golden Graham cereal.
- Chocolate Chips: We like semi sweet, but milk chocolate will work too.
HOW TO MAKE S’MORES BROWNIES FROM A BOX MIX
- PREP: Preheat the oven to 350 degrees. Mist a 9×13 pan with baking spray. Gather ingredients and cut the graham crackers into 1 inch pieces.
- MIX: Mix the brownie batter according to the package directions.
- BAKE: Pour into the prepared pan and bake according to the box, subtracting 5 minutes from the baking time.
- TOP: Carefully remove the brownies from the oven. Sprinkle with the mini marshmallows, chocolate chips, and graham cracker pieces.
- BAKE TWICE: Bake an additional five minutes, or until the marshmallows are lightly toasted and the chocolate pieces are melted.
- Baking Pans: For these brownies, I use a 9×13 pan (affiliate). The thinner brownie layer is the perfect amount of chocolate and a firm base to hold all of the toppings.
- Brownie Knife: Did you know that a plastic knife (affiliate) is actually best for brownies? I don’t know what kind of magic happens, but almost zero brownie sticks to the plastic!
- Airtight Containers: Keep your brownies fresh longer with a quality container (affiliate). This set is my go-to for brownies, cakes, and cookies.
BROWNIE RECIPE TIPS
Of course! I have an amazing brownie recipe that would serve as an excellent base to this recipe. I like a box mix for ease, but nothing beats from scratch.
These brownies should be stored covered at room temperature. If stored properly, they should last 4 to 5 days. Although, by day 5 the marshmallows will start to stale a bit.
No. Unfortunately, these brownies are not freezer friendly due to the toppings.
Yep! To make s’mores brownie bites, generously mist a mini muffin tin with baking spray. Spoon the batter into each cup almost to the top. Bake 5-6 minutes, or until they are almost baked fully, add toppings, and bake 5 minutes more.
