Preheat oven to 350 degrees F. Spray a 9x13 baking dish with nonstick spray. Line with parchment paper for easy removal. Set aside.
Layer the bottom of the pan with the graham crackers. If needed, break the crackers to fill any gaps between the crackers. Set aside.
8-12 honey graham cracker sheets
In a large bowl, whisk together the butter, sugars, and vanilla until well combined.
1 cup unsalted butter, 1 ½ cups light brown sugar, ½ cup granulated sugar, 1 tablespoon vanilla extract
Stir in the eggs, one at a time, mixing well after each addition.
4 large eggs
Add flour, cocoa powder, and salt. Stir until just incorporated.
1 ¼ cups all-purpose flour, 1 cup unsweetened cocoa powder, 1 teaspoon kosher salt
Pour batter evenly into the prepared baking dish on top of the graham crackers. Sprinkle chocolate chips on top of the batter in the pan.
1 cup semisweet chocolate chips
Bake for 20 minutes. The brownies will still be underdone, but this will allow you to add the marshmallows.
Sprinkle marshmallows evenly over the top of the underbaked brownies. Return them to the oven and bake for an additional 8-10 minutes.
1-2 cups mini marshmallows
Cool brownies for about 10 minutes before adding the Hershey’s bar pieces and broken graham cracker pieces on top.
1- 2 Hershey’s chocolate bars
Cool brownies for about an hour before lifting them out of the pan and cutting into bars.

Graham crackers: Feel free to substitute chocolate graham crackers if you prefer.
Unsalted butter: You can use salted butter in place of the unsalted butter. If using salted butter, decrease the salt to 1/2 teaspoon.
Vanilla extract: You can decrease the vanilla to 1 teaspoon if you prefer.
Flour: To properly measure the flour, either weigh it (click "metric" just above the ingredients for the weights) or sift, lightly spoon into the measuring cup, and level.
Cocoa powder: I use unsweetened cocoa powder and haven't tried using Dutch process cocoa powder in this recipe.
Hershey’s Milk Chocolate Bars: Feel free to substitute your favorite type of chocolate bar or even additional chocolate chips.
