Preheat the oven to 350.
Line a 9x12 baking sheet with parchment.
In a food processor add graham crackers, sugar, salt, butter and eggs. Pulse until crackers are a fine crumb. Pour in your prepared baking sheet. With your hands, flatten the mixture into an even layer being sure to press into the corners.
Bake in the oven for 10 minutes.
Remove baking sheet from oven and sprinkle chocolate chips evenly across the hot crust and allow to melt for a few minutes. Spread melted chocolate in an even layer and allow to completely cool, about 30 minutes.
Top with marshmallows and broil for 1 minute or until the marshmallows brown along the top. Remove from the oven and cut into squares.
