1 package brownie mix
2 cups mini marshmellows
1 cup Teddy Grahams or broken up graham crackers
9 oz milk chocolate bars broken up into pieces. (I used 6 regular sized Hershey's Bars)
Preheat oven to 350 degrees.
Make brownie mix according to the directions on the package. Put 2//3 of the batter in a greased 9x13 pan. Reserve the other 1/3 of the batter. Bake foe 15 minutes.
Remove from oven and sprinkle the marshmellows, chocolate and grahams over the top.
Then sprinkle the rest of the batter on top. I swirled it in lines up, down and then across. It makes a delicious top crust.
