Oreo Ice Cream Sandwich Cake for 12

Instructions:

1. Line a 9x13-inch baking dish with parchment paper, leaving an overhang on the sides to act as a sling.
2. Arrange the ice cream sandwiches in a tight single layer at the bottom of the dish, trimming edges with a knife if necessary to create a seamless base.
3. In a large bowl, gently fold the coarse Oreo crumbs and vanilla extract into the whipped topping using a rubber spatula until evenly distributed.
4. Spread the whipped topping mixture evenly over the ice cream sandwich layer, smoothing the top with an offset spatula.
5. Sprinkle the fine Oreo crumbs across the top of the cream layer.
6. Drizzle the warmed hot fudge sauce in a zigzag pattern over the crumbs.
7. Press one whole Oreo cookie into each of the 12 sections to designate serving sizes.
8. Place the dish in the freezer for at least 3 hours until the edges are firm to the touch.
