1Line the bottom of a 9"x13" baking pan with aluminum foil or parchment paper. Preheat oven to 350 degrees F.
2Break up the graham crackers into large pieces and drop into prepared pan. Layer on top of the graham crackers in following order: raisins or cranraisins, chocolate chips, and chopped pecans. Bake this till the chocolate chips have just melted, about 10 mins.
3Pull from oven and top with the small marshmellows. Place pan back in oven under the broiler for about 5 to 10 mins or until the marshmellows are soft and a golden brown color.
4Lift the foil or parchment paper out of the pan and place on a serving plate. Serve warm.
Optional: You can put out small bowls of chocolate sauce, crushed pineapple, crushed strawberries, carmel sauce, or whatever you like to dip this in.
