When you don’t want to make a campfire to have a yummy graham cracker, chocolate and marshmallow treat, enjoy these S’mores Brownies straight out of the oven! These are what summer’s all about!
I always crave s’mores all summer long. Are you the same? We went camping a few weekends ago and of course got to enjoy some around the fire. Whoever was the first one to put roasted marshmallows, chocolate, and graham crackers together was pure genius!
The other day I was thinking about how amazing it would be to add brownies to the traditional s’more. Have you seen how people are switching them up now? They’ll add various candy bars instead of plain chocolate bars or sub in different cookies for the graham cracker. I love it!
I have a favorite brownie recipe that I knew would be even better when combined with melty, gooey marshmallows, chocolate pieces and a graham cracker crust.
This is quite possibly my favorite dessert of all time! It’s so wickedly-delicious, and so worth every calorie! Don’t skip the broiling the marshmallows step. Sure, you can just melt some marshmallows on top in the oven, but the broiling gives them that gorgeous golden brown color and sends the flavor to the next realm of glorious. You’ll need to watch the brownies the entire time they are broiling so you can remove them quickly, right when they’re done. Even a few seconds can mean the difference between burnt marshmallows and perfectly browned marshmallows!
Did you catch my Instagram story about what happened during the first round of making these brownies? I wasn’t thinking and lined the pan with parchment paper so it was hanging over the edges. So when I put it under the broiler, the paper caught fire, along with half of the marshmallows. Luckily I was watching it closely and saw that happen. So I furiously blew out the flames and then removed the top part of the marshmallows where they had blackened. I got a good laugh out of that one.
Sometimes I amaze myself, but not in a good way, lol. Don’t worry, we still devoured them. They just weren’t very suited for photographing, so I had to re-make them. Oh darn! I’m not opposed to enjoying these beauties twice in one week!

S’mores Brownies
Ingredients
- Graham Cracker Crust:
- 3 c. graham cracker crumbs
- 3/4 c. 1 1/2 sticks butter, melted
- 1/8 c. sugar
- Brownies:
- 3/4 cup 1 1/2 sticks salted butter, sliced
- 1/2 cup semi-sweet chocolate chips
- 1 cup brown sugar
- 1/4 cup granulated white sugar
- 2 tsp. vanilla extract
- 2 large eggs
- 2 Tbsp. milk 2% or greater
- 1 1/4 c. all-purpose flour
- 1/3 cup baking cocoa
- 1/4 tsp. baking powder
- Scant 1/2 tsp. salt
- 1 tsp. corn starch
- About 1 pkg 12 oz. regular-sized jet-puffed marshmallows (not mini)
- 6 oz. COLD Hershey candy bars keep in the fridge until ready to use (I used fun-sized)
Instructions
- Preheat the oven to 350 degrees Fahrenheit. Spray a 9"x13" pan with nonstick baking spray.
- In a large bowl, stir together graham cracker crumbs, melted butter and sugar until all the crumbs are coated and moist. Press into the pan. Use the bottom of a measuring cup to pack the crumbs down.
- Bake crust for 9-10 minutes.
- While the crust is baking, make the brownies. In a large microwave-safe bowl, melt butter and chocolate chips together in 30 second increments, stirring between. Stir mixture until smooth. Quickly whisk in (by hand) brown sugar, white sugar, vanilla, eggs, and milk, just until incorporated (don’t over-mix or brownies will be tough and lose their nice texture). Add flour, baking cocoa, baking powder, salt and corn starch to the bowl and stir by hand just until incorporated.
- Quickly and carefully pour and spread brownie mixture over baked crust (batter will start to melt and bake on the hot crust). Bake for approximately 15-16 minutes, or just until brownies are set.
- While brownies are baking, cut the marshmallows in half. Break apart chocolate bars and keep in the fridge.
- Immediately after brownies are done baking, remove them and set the oven to BROIL. Place the marshmallows on the top of the baked brownies, cut side down, close together so they're touching each other. Place the brownies under the broiler and watch them THE ENTIRE time, just until the marshmallows are golden brown (this took less than a minute for me). Immediately remove them and push cold chocolate bar pieces into the marshmallows. Immediately place the brownies in the fridge so the chocolate pieces won't melt too much. Let brownies cool completely in the fridge, so the chocolate pieces can harden, then remove them and store at room temperature. Slice and serve.
This is what heaven in a pan looks like! I dare you to stop at just one! I hope you love these like we do!
