Pre-heat oven to 180C (350F). Grease a 9-inch springform pan.
In a medium bowl mix together cookie crumbs, sugar, and butter until combined and wet sand-like texture. Press into the base of the springform pan and use the back of a spoon or small bowl to press in.
Bake for 10 minutes, set aside to cool.
In a large microwavable bowl melt chocolate and butter together. Stir in both sugar and then eggs into a smooth batter. Fold in flour and chopped chocolate pieces until just combined.
Pour caramel sauce over cooled cookie base. Pour brownie mix over top and spread to the edges, evenly. Bake in the oven for 35-40 minutes until a toothpick comes out with some crumbs, just set.
Sprinkle marshmallows over entire top of brownie and place under the grill for 2-3 minutes to toast marshmallows. Keep a close eye on them to not burn.
Let cool for 30 minutes and cut.
Enjoy!
