These S’mores Brownies might be one of my all-time favorite brownie recipes: a crispy graham cracker base, ultra-fudgy brownie layer, and gooey toasted marshmallows on top. They taste exactly like a s’more but even better… and you don’t even need a campfire! They are super easy to make, I know you’re gonna make them on repeat all summer long!

I cannot get enough of these S’mores brownies! When I was recipe testing them, I kept taking lots of extra bites and blamed it on quality control (LOL)- they are that good!

As a professional baker I have made a TON of brownie recipes, but these are coming in strong at the top of the list. The texture from the graham cracker crust along with the gooey, fudgy brownie center, and the toasted marshmallows on top is recipe perfection!

Because brownies are such an easy dessert I went on a brownie rampage recently and made a ton of new recipes. Like these gooey marshmallow brownies that have mini marshmallows inside (!!) a gooey center, and these super fun sprinkle filled birthday brownies!

Something I recommend everyone should have in their kitchen is a tiny torch. Especially if you love s’mores. It makes toasting marshmallows or meringue for an incredible s’mores pie SO much easier and it’s not scary to use at all! It’s mini and cute, and you need to get one.

Because of my love for toasting marshmallows, I always keep minis on hand so I can make these S’mores muffins or this Mississippi Mud cake!

Making S’mores Brownies

Prepare for baking: Preheat the oven to 375° F and line an 8×8 inch pan with parchment paper or spray with nonstick baking spray. Set aside. Only the crust gets bakes on 375, then well lower the oven to 350 to bake the brownies.

Assemble and bake the graham cracker crust: In a small bowl melt the butter, then add the graham cracker crumbs and sugar. Mix until the mixture resembles wet sand. It should stick together when pressed.

TIPS FOR RECIPE SUCCESS

  • Be sure not to over bake the s’mores brownies- they should look shiny when done. A toothpick inserted into the center should come out with a few moist crumbs.
  • If you don’t have a kitchen torch, use the oven. Bake them for 2-3 minutes on 400° on the top rack so the marshmallows get golden brown.
  • You can also use your broiler with the brownies on the bottom rack for 15 seconds but only if you arent using parchment paper. Otherwise it can catch fire. Don’t broil the marshmallows any longer because they can catch fire too! Please be very careful!
  • If you only have large marshmallows, cut them into quarters and place them on top. I have not tested this recipe using marshmallow fluff.

Ingredients

Graham Cracker Crust:

  • 3 tbsp (3 tbsp) unsalted butter, melted
  • 1 cup (84 g) graham cracker crumbs
  • 1 tbsp (1 tbsp) sugar

Brownies:

  • 1/2 cup (113.5 g) butter
  • 6 oz (170.1 g) semi sweet chocolate chips , about 1 heaping cup
  • 3 (3) large eggs
  • 1 cup (200 g) white sugar
  • 1 tsp (1 tsp) vanilla extract
  • 1/2 cup (62.5 g) flour
  • 1/4 cup (21.5 g) cocoa powder
  • 1/2 tsp (0.5 tsp) salt
  • 2 cups (150 g) mini marshmallows, or 10 oz bag

Instructions
 

  • Preheat the oven to 375° F and line an 8×8 inch pan with parchment paper or spray with nonstick baking spray.
  • In a small bowl melt the 3 tbsp butter. Add the 1 cup graham cracker crumbs and 1 tbsp sugar. Mix to combine until the mixture resembles wet sand. It should be able to stick together when pressed.
  • Press the mixture into the pan so that it is packed down. I like to use the bottom of a ⅓ cup measuring cup to press the crumbs down, around, and up the sides of the pan.
  • Bake the crust for 8 minutes, then lower the oven to 350°.
  • In a microwave safe bowl combine the 1/2 cup butter and 6 oz chocolate. Microwave for 30 seconds at a time stirring in between until the chocolate is totally melted.
  • Add in 3 eggs and 1 cup sugar and whip using a whisk or the whisk attachment on high speed for 2 minutes.
  • Switch to a spatula and add in 1 teaspoon vanilla mix until combined. Next add in the 1/2 cup flour, 1/4 cup cocoa powder, and 1/2 tsp kosher salt. Mix until combined.
  • Pour the batter into the lined baking pan and bake for 35-38 minutes.
  • Top the brownies with 2 cups of mini marshmallows and torch with a kitchen torch.

If you dont have a torch

  • You can broil the brownies ONLY if you didnt use parchment paper (it will catch fire) and ONLY for 15-30 seconds- the marshmallows can catch fire so you have to be SUPER careful! Broil them on the lowest rack in your oven. If you used parchment paper you can just bake the brownies for 3-5 more minutes on 400 but they won’t get as golden brown.
  • Sprinkle with more graham cracker crumbs and pieces of hersheys chocolate and enjoy!

Notes

I recommend that you get a kitchen torch for this and other recipes that you like to make that require direct heat. You can find a link to the one I have in the post.
They are easy to use and a lot less risky than broiling marshmallows in the oven.
Please be SUPER careful if you decide to broil the brownies! 

STORAGE AND FREEZING

Storing: Once the marshmallow layer is cooled, the brownies can be stored in an airtight container, at room temperature, for up to 5 days.
Freezing: To freeze s’mores brownies, once cooled, wrap them in plastic wrap, then store them in a freezer-safe bag or container and freeze for up to 3 months. Thaw overnight in the refrigerator before serving.
