In a medium bowl, whisk fudge topping and 1 – 2 cups whipped cream until well blended.
Add the dry pudding mix and stir for a few minutes. Add 1 cup chopped cookies and mix until blended. Set aside.
Place 4 ice cream sandwiches, side-by-side, on a foil-lined cookie sheet. Add half the whipped cream pudding mixture on top, then repeat layers.
Add the last 4 sandwiches, then cover the entire cake with the remaining whipped cream making sure to add the rest of the chopped cookies to the cake (you can add them to the top or all over the cake).
Freeze cake for 1 hour, then lightly wrap with foil and continue freezing for an additional 2-3 hours.
Oreo studded Ice Cream Sandwich Cake is cool, creamy, and refreshingly delicious. It is perfect for hot summer days!!
