With all the flavors of s'mores -- chocolate, marshmallows, and graham crackers -- these rich, gooey brownies are perfect for summer, fall, or any time of year!
Preheat oven to 350 degrees Fahrenheit.
Line a 9x13 pan with parchment paper.
Make a layer of graham crackers.
Mix oil, sugar, vanilla, and eggs in a large mixing bowl.
Add flour, cocoa powder, and salt and mix well.
Pour brownie batter over graham crackers.
Bake for 25-30 minutes, until a toothpick inserted in the middle comes out clean.
Pull brownies out of the oven and immediately add a layer of mini-marshmallows and broken graham cracker pieces.
Heat oven to broil and put the brownies on the top shelf. Watch VERY CAREFULLY and start checking after 30 seconds. As soon as the marshmallows are golden brown, remove from the oven (won't take longer than 45-50 seconds).
Cool completely and remove by lifting the parchment paper from the pan. Cut into small squares using a wet knife. Enjoy!
