  • 1 1/2 cups (180 g) all purpose flour
  • 1 package (9 full rectangles, 135 g) graham crackers (pulsed into crumbs)
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 12 tablespoons (170 g, 1 1/2 sticks) unsalted butter melted
  • 1 1/2 cups (320 g) packed light brown sugar
  • 2 large eggs room temperature
  • 2 teaspoons natural vanilla extract
  • 30 mini Hershey bars (or you can use full size) (or 2-3 cups milk chocolate chips)
  • 3-4 cups mini marshmallows (or large ones cut in half)


  • Position a rack in the center of your oven. Preheat the oven to 350F. Lightly coat a 9 by 13 baking pan with cooking spray or line with parchment paper.
  • Whisk together flours, graham cracker crumbs, baking powder and salt into a bowl. Set aside.
  • In a second mixing bowl, whisk together melted butter, brown sugar, eggs, and vanilla.
  • Add dry ingredients and mix until just combined, 5 to 10 seconds. Spread batter into prepared pan.
  • Bake for about 22-25 minutes, or until the top is set and golden brown. Bars may appear to be not done, but they will set up as they cool.
  • Remove the pan from the oven. Layer the top with the chocolate bars. Top with marshmallows.
  • Turn the oven to broil and return the bars to the oven for 1 to 2 minutes or until the marshmallows are lightly toasted. Keep a close eye on them so they don't burn! Set the pan on a wire rack and cool completely before cutting into bars.


  • Storage: You can store these at room temperature for up to 3 days. Just make sure they are covered.
  • Swap Out The Mini Marshmallows - Use large marshmallows but cut them in half first.
  • Be sure to measure your flour correctly. Over-measuring can result in a cakey texture instead fo the perfect chewiness that we are going for. You can get the full tutorial on how to measure your flour here.
  • Make sure your ingredients are room temperature, like your eggs. To bring your eggs to room temperature quickly place them in a bowl of warm water for 10 minutes.
  • Do not overbake. They may appear not done at this time, but taking them out during that time, ensures you won’t overbake them! 
  • Watch The Broiler! Once the marshmallows are on and they are under the broiler. Be careful. They can burn quickly!
  • Graham Cracker Crumbs:To make graham cracker crumbs, pulse crackers in a food processor until finely ground.
