In a large baking dish, add the marshmallows and top all of them with the melted butter.
Add the chocolate bars, the crackers, crushing them into smaller pieces and top everything with the caramel topping, spreading it well all over the crackers.
Take to a preheated oven at 200° C (400° F) and bake for 15 minutes.
After this time has passed, using a spatula, mix everything very well until combined.
Then add another hundred grams of crushed crackers, the chocolate chips, mix everything once again and spread evenly on the baking dish.
Take to the fridge and let it chill for at least 2 hours.
Serve.
