S’mores Brownies on Graham Cracker Crust

It’s still summer to us, even if school is back in session in some parts of the country! The days are warm and the sun is shining and the evenings are perfect for s’mores! We took our s’mores a step further and made our favorite brownies on top of a graham cracker crust, topped with roasted marshmallows and dark chocolate. These are perfect for lunch boxes and you can bet … the kids will be asking for s’more!

S’mores Brownies on Graham Cracker Crust

Servings 16 2-inch squares
Prep Time 15 minutes
Cook Time 35 minutes


  • 8 x 8 inch square baking pan


Graham Cracker Crust

  • 1 1/2 cups graham crackers
  • 5 tablespoons butter, melted


  • 4 oz. bittersweet chocolate we use Trader Joe’s dark chocolate or Ghiradelli’s 60% cacao chocolate chips
  • 2 tablespoons unsweetened cocoa powder
  • 4 oz. unsalted butter
  • 1 dash salt
  • 1/2 cup granulated sugar
  • 2 eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup all-purpose flour
  • 1/2 teaspoon baking powder


  • 2 cups mini marshmallows
  • 1 1/2 cups dark chocolate chips


Graham Cracker Crust

  • Preheat oven to 350 F. Grease or spray an 8-inch square baking dish. Set aside.
  • Mix graham cracker crumbs with melted butter and pat into the bottom of the prepared 8 x 8 inch baking dish.
  • Bake for 10 minutes at 350 F.
  • Remove from oven and cool.


  • Melt bittersweet chocolate, cocoa powder, and butter in a medium sized pot over low heat on the stove and stir until well blended. Remove from heat.
  • Add salt and sugar and stir until both are dissolved in to the chocolate-butter mixture.
  • Add eggs, one at a time, mixing thoroughly after each.
  • Stir in flour, baking powder, and vanilla and mix well.
  • Carefully spread the brownie batter over the cooled graham cracker crust in the baking dish.
  • Bake at 350 F for 18 minutes. (If you are using a glass baking pan, reduce the heat to 325 F and bake slightly longer.)
  • Test brownies with a cake tester and if the brownies still seem too wet, bake for one or two minutes longer. The brownies should be just slightly wet in the center when they are done baking.
  • Remove the brownies from the oven and sprinkle mini marshmallows evenly on top of the brownies. Keep the oven at 350 F.
  • Return the brownies to the oven for another 4-5 minutes, or until the marshmallows are all melted.
  • Remove from oven and immediately sprinkle dark chocolate chips over the top. Do not return to the oven. The heat from the brownies and roasted marshmallows will melt the chocolate chips.
  • Once the chocolate chips are melted, you can leave them just like they are, or you can spread them evenly over the top with a spatula for a thin chocolate layer.

  • Allow brownies to sit for at least 30 minutes before cutting them, if serving hot, or chill if serving cold.


We like to keep the chocolate chips in tact once they are melted, but if you are inspired to make a pretty chocolate layer on top you can certainly do so. The chocolate can mix with the marshmallows, though and become a bit of a mixture!
We like to serve those brownies slightly warm or at room temperature, so they are still a bit gooey. They can be a bit messy to eat, but they are oh so delicious!
