One 9-ounce package chocolate wafer cookies (preferably Nabisco)
Directions
Line an 8-by-4-inch loaf pan with two layers of plastic wrap, leaving excess hanging over the sides.
In the bowl of a stand mixer fitted with the whisk attachment, whip the heavy cream until it begins to fluff, about 1 minute. Add the caramel sauce and salt, and continue to whip until soft peaks form.
Spread a thin layer of whipped cream in the bottom of the prepared loaf pan. Place one cookie on its edge against the long side of the pan. Spread about 1 tablespoon of whipped cream on another cookie and place against the right of the last one, pressing gently. Repeat 8 times to make a row of 10 cookies, then repeat the process to make 3 total rows.
Cover with whipped cream, then fold over the plastic wrap tightly against the cake. Refrigerate for at least 3 hours or up to 1 day, then remove from the pan and cover with another layer of whipped cream.
Slice and serve with the remaining whipped cream and crumbled wafer cookies.
