  • 2 cups graham cracker crumbs
  • 2 cups all-purpose flour
  • 1/2 cup sugar
  • 1/2 teaspoon baking powder
  • 1 teaspoon vanilla extract
  • 1 cup butter melted
  • 20 ounces dark chocolate chunks 1 cup reserved
  • 5 cups mini marshmallows


  • Grease a 9 x 13 inch baking pan and preheat oven to 375°F.
  • In a mixing bowl combine graham cracker crumbs, flour, sugar, baking powder, butter and vanilla.
  • Press mixture into a flat layer in the bottom of baking dish. Bake 15 minutes until top is lightly brown.
  • As soon as graham cracker crust comew out of the oven sprinkle all but 1 cup of chocolate chunks evenly and allow them to melt. Use a butter knife or spatula to press down, spread out and help the chocolate melt evenly. The heat from the crust will melt the chocolate.
  • Add marshmallows and then remaining chocolate chunks. Place under a pre-heated broiler for 30 seconds or so until the marshmallows are toasted just like a campfire.


  • When using the broiler do not step away from the oven. Watch closely and check every ten seconds. Toasting the marshmallows happens VERY quickly!
  • The melty chocolate is ooey gooey and is irresistible served warm. Even as the dish cools the chocolate will be very gooey when left in the heat on a hot summer day, so have some forks and plates ready to help enjoy this snack.
  • Chocolate chunks are much more similar to Hershey's bars and look more like smores than using regular chocolate chips.
  • Chocolate chips may be melted and pieces of a Hershey chocolate bar may be sprinkled on top if desired, but I really love the flavor that dark chocolate adds to this dessert.
  • Pan may be lined with parchment paper if desired to make bars easier to remove, cut and serve.
  • Store in an air tight container for 3 - 5 days on the counter. If the environment is warm place container in the refrigerator to help keep the chocolate a bit more firm.
