In a medium-sized saucepan, add 1 1/2 cups of milk chocolate chips, 3 tablespoons of milk, and 1 1/3 cups of miniature marshmallows. Heat over medium-high heat, stirring constantly for about 2 to 3 minutes until the mixture is smooth and glossy.

Carefully pour the melted mixture into a 9-inch pie dish, spreading it evenly across the bottom with a spatula.

Now, sprinkle the remaining 4 cups of miniature marshmallows evenly over the chocolate layer in the pie dish.

Preheat your broiler to high and place the pie dish in the oven for about 1 to 3 minutes, watching closely.

Once the marshmallows are toasted to perfection, carefully remove the dish from the oven and serve immediately with dippers.
