In a small bowl, mix the Cool Whip with your scoop of protein powder (add marshmallow fluff if desired).
Spray a 9 x 9 inch baking dish with non stick spray and lay out a single layer of graham crackers.
Spread the creamy filling evenly across the crackers. Pop the whole thing in the freezer for 10-15 minutes to firm up.
Melt the chocolate chips with coconut oil in a microwave-safe bowl in 30-second intervals until smooth.
Pour the melted chocolate over the frozen whipped topping layer and smooth it out with a spatula.
Place the remaining graham crackers on top, gently pressing down. Freeze until firm, about 1-2 hours.
Break or slice into squares, wrap individually in plastic wrap, and store in an airtight container or freezer bag for best results.
