These S'mores Brownies are a decadent dessert that no one can resist

Everyone loves smores brownies, which take the humble brownie to an entirely new level! During baking, the graham crackers soften and the marshmallows melt to make an ooey gooey treat that’s out of this world yummy! You don’t need to toast the marshmallows, as the surface becomes golden brown from the baking alone.

S’mores brownies are a serious crowd pleaser that’s perfect for game day, potlucks and parties. I whipped them up for a 4th of July bash and they disappeared in minutes!  I’ve also made them for movie night and kids birthdays with rave reviews.


They definitely rival S’mores Pizza and S’mores Cookie Skillet as our top s’mores dessert… When the weather’s too hot for baking, try making these No Bake S’mores Brownies instead.

Making smores brownies is straightforward using five simple ingredients:

  • Brownie mix
  • Ingredients called for on the brownie mix box, oil and egg etc.
  • Graham cracker sheets
  • Milk chocolate bars
  • Marshmallows

Then grab a 9×13-inch rectangular baking dish and add the ingredients in layers with the marshmallows on top. Half the brownie batter goes in as a layer on the bottom, and the remaining half is drizzled over top to moisten the marshmallows before baking.

The baking is a single step with no need for broiling or removing the pan in the middle to add a layer. Nice and easy!

Can I make s’mores brownies ahead of time?

Yes, you can bake these up to 3 days ahead of time. Cover the pan with plastic wrap and store in a cool, dry place. Before serving, reheat in the oven at 250°F (121°C) for 15 minutes to regain their delicious ooey gooey texture.

You can also freeze smores brownies for up to 3 months. Wrap them in wax paper or foil and place in a ziptop bag or another airtight container. Let them thaw completely before reheating or consuming.


  • Rectangular baking dish: A Pyrex baking dish is ideal for this recipe.
  • Whisk: Use a whisk to remove lumps in the brownie batter before pouring into the pan.
  • Cake tester: A cake tester or toothpick allows you to check doneness while baking.
