Equipment

  • 9 x 13 baking dish

Ingredients

  • 6 tablespoons butter melted
  • 3 cups graham cracker crumbs
  • 14 ounce can sweetened condensed milk
  • 1/4 teaspoon salt
  • 1 teaspoon vanilla extract
  • 1 cup semi sweet chocolate chips
  • 2 cups mini marshmallows divided
  • 10 snack size Hershey bars break into individual bars
  • parchment paper OR nonstick cooking spray

Instructions

  • Prep: Preheat oven to 350 degrees. Line a 9×13 baking pan with parchment (hang some over the sides so it’s easier to remove the cookie bars) – or lightly spray with nonstick cooking spray.
  • Make the crust: To a large bowl, add melted butter and graham cracker crumbs. Stir to combine.
  • Transfer graham cracker mixture to the baking dish and press evenly into the bottom to form the crust. Bake 8 minutes. Remove from the oven and cool 10 minutes. (reserve the bowl – you’ll use it in the next step).
  • Toppings: To the same bowl, blend the can of sweetened condensed milk, salt and vanilla extract together. Set aside.
  • Layering: Evenly sprinkle all of the chocolate chips over the top of the crust and 1 cup of the marshmallows.
  • Drizzle reserved sweetened condensed milk blend over the top.
  • Bake: 12 minutes. Remove from the oven, sprinkle the remaining marshmallows over the top and bake another 10-12 minutes or until marshmallows are golden. Optional: broil 1 minute for darker golden brown color. 
  • Cool: Remove from the oven, cool 15 minutes then gently press mini Hershey bars into the top of the cookie bar. NOTE: if you add the Hersheys before it’s cooled, they’ll melt into the bars.
  • Slice and eat: Cool completely before slicing (optional refrigerate) then use a sharp knife to slice into squares.
