"Gimme Thrive" S'mores Brownie Bars

by Julie Finlayson


  1. Preheat oven to 350 degrees.Line a 9x9-inch pan with foil and spray the foil with nonstick cooking spray.
  2. Combine graham cracker crumbs, sugar, and melted butter in a medium bowl and stir till evenly combined. Press into the pan and bake for 15 minutes.
  3. In a mixing bowl, combine the brownie mix and hot water. Stir just until combined. Add in the milk chocolate pieces and stir to evenly distribute (do not overstir).
  4. Pour the brownie mix carefully over the crust. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out nearly clean.
  5. Turn the oven to broil. Place the large marshmallows evenly over the top of the brownie layer, flat sides up. Broil until golden brown, watching carefully so as not to burn the marshmallow tops.
  6. Cool completely. When ready to serve, carefully lift foil liner and set on a cutting surface. Spray a knife with nonstick cooking spray to aid in cutting the bars. (You may have to wipe down the knife and repeat the spraying.)
