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! These black forest brownies are also great for summer!

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

If you arent familiar with s’mores I can tell you that they have been a popular camping treat for decades! They were created in the early 1900s, and are made up of graham crackers, chocolate bars, and marshmallows all sandwiched and melted together until gooey and delicious!

Marshmallows are also so much fun to add to desserts like this Mississippi Mud cake– make sure to get the minis- they are easier to work with!

INGREDIENTS NEEDED

Ingredients for s'mores brownies.
Mini marshmallows are recommended for this recipe.
  • Unsalted Butter – This not only adds moisture to the brownies but also gives a rich buttery flavor throughout. It also helps form the crust.
  • Graham Cracker Crumbs -Makes up the crunchy graham cracker base. If you don’t have the crumbs, mash up about 9 graham crackers in a food processor or crush them in a zip top bag.
  • Semi-Sweet Chocolate Chips – Use high-quality semi-sweet chocolate chips for a deep and fudgy flavor.
  • White Sugar – This sweetens up the base of the brownie batter.
  • Eggs – When added to brownie batter, eggs help bind everything together and produce a dense, fudgy texture.
  • Vanilla Extract – This helps to add flavor to the brownies and enhances all the other flavors.
  • Flour – This gives the s’mores brownies structure. All-purpose flour works best in this recipe.
  • Kosher Salt – A pinch of salt will help to balance out the sweetness and enhance all the flavors.
  • Unsweetend Natural Cocoa Powder – Enhances the chocolate flavor while adding a rich brown hue to the brownies.
  • Marshmallows – These get added on top to create gooey s’mores topping. Mini marshmallows are the best to use. If you only have the large ones, cut them in quarters.

HOW TO MAKE 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. Press the mixture into the pan so that it is packed down, around, and up the sides of the pan. I like to use a 1/3 cup measuring cup to press it in well. Bake the crust for 8 minutes, then lower the oven to 350°.

Melt the chocolate: To a microwave-safe bowl, add the butter and chocolate. Heat for 30-second at a time stirring in between, until the chocolate is fully melted.

Make the brownie batter: To the chocolate mixture, add the eggs and sugar and whisk until fully combined for two minutes, then add the vanilla extract. Fold in the cocoa powder, salt, and flour until just combined.

Bake the brownies: Pour the brownie batter on top of the graham cracker crust and bake for 35-38 minutes.

Toast the marshmallows: Remove the brownies from the oven and evenly distribute the marshmallows on top. Use a kitchen torch to toast the marshmallows until golden brown on top. (see notes below for using the oven).

Garnish and serve: While the marshmallows are still sticky, sprinkle with additional graham cracker crumbs and chocolate. Let cool down and enjoy!

TIPS FOR RECIPE SUCCESS

  • When pressing the crust into the pan, use a 1/3 cup measure to ensure an even, packed-down layer.
  • 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! This is why I recommend a kitchen torch, its a lot less scary!
  • If you only have large marshmallows, cut them into quarters and place them on top. I have not tested this recipe using marshmallow fluff.

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.

With a crunchy graham cracker crust, fudgy dark chocolate center, and gooey marshmallow top, these s'mores brownies are sure to satisfy anyone who loves s'mores!

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.
  • Graham cracker crumbs mixed with melted butter in a glass bowl.
    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.
  • Graham cracker crust pressed into a brownie pan.
    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.
  • Wet brownie batter ingredients in bowl.
    Add in 3 eggs and 1 cup sugar and whip using a whisk or the whisk attachment on high speed for 2 minutes.
  • Dry ingredients added to brownie batter in a glass bowl.
    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.
  • S'more's brownie batter in a 8x8 pan.
    Pour the batter into the lined baking pan and bake for 35-38 minutes.
  • S'mores brownies in a brownie pan.
    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.

Notes

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!
