Prepare the Marshmallow Mixture: In a large mixing bowl, combine the milk, marshmallow creme, and thawed Cool Whip. Mix well until you achieve a smooth and fluffy consistency.
Layer the Graham Crackers: On a baking sheet, lay down a single layer of graham crackers—these will be the base of your ice cream sandwiches.
Spread the Marshmallow Mixture: Generously spread the marshmallow mixture over the first layer of graham crackers.
Add the Chocolate and Marshmallows: Next, layer the chocolate bars and sprinkle mini marshmallows on top of the marshmallow mixture, just to add an extra item of deliciousness!
Top with More Graham Crackers: Place another layer of graham crackers over the fillings and press down gently to secure the layers.
Freeze: Pop the entire baking sheet into the freezer and let it chill for at least 4 hours or until completely firm.
Serve & Enjoy: Cut the firm dessert into squares or rectangles and serve! Enjoy the delightful taste of summer in your kitchen anytime.
