Build the cake layers
- Spread the softened chocolate ice cream into the bottom of a 9x13 pan or a 10-inch springform, smoothing into an even layer. Place it in the freezer for 1 hour until firm, looking for no soft spots when pressed lightly.
- Mix the crushed Oreo cookies with the hot fudge sauce until the crumbs are evenly coated and resemble a thick crunch filling. Spread the Oreo crunch layer evenly over the frozen chocolate ice cream.
- Freeze the layered cake for 30 minutes. Chill until the Oreo crunch layer feels set to the touch, not tacky.
- Spread the softened vanilla ice cream over the Oreo crunch layer and smooth completely to seal the edges. Freeze for at least 4 hours until the top is solid and sliceable.
- Top with whipped topping and smooth or lightly mound it for a classic finish. Drizzle the chocolate shell (or ganache) over the top and add colorful sprinkles.
- Freeze at least 2 more hours before serving. Keep it fully firm so slices hold together and the fudge-soaked Oreo layer stays clearly defined.
Notes
For the cleanest slices, run a sharp knife under hot water, wipe dry, and cut straight down between freezes. Store covered in the freezer for up to 2 weeks. Freezing is best (freezer yes; fridge storage is not recommended). For a lighter option, use reduced-fat ice cream and a lower-sugar whipped topping substitute while keeping the same layer method.
