Do you have family members that love something so much they eat it every day? Both of my grandfathers LOVED ice cream. They ate it every single night. And we're not talking small demure scoops. We're talking BIG cereal bowls of ice cream. And boy, were they happy people! And fit as well.
Spray a 5 x 9" loaf pan with cooking spray. Line with a piece of parchment paper large enough to hang over the sides and spray again.
Reserving about four cookies, put the rest of the amaretti into a food processor with the butter. Pulse several times to combine and then run until butter is incorporated about 30 seconds. The crust will clump together and pull away from the sides of the bowl. (Alternatively, crush the cookies in a ziploc bag with a rolling pin and combine in a bowl with the very softened butter until completely blended).
Pour crumbs into prepared loaf pan. Press down firmly to pack the crumbs in the pan. I sometimes spray a piece of plastic wrap or parchment paper and use it to push the crumbs down into the pan. Flatten the crust that it's level. Place in the freezer for a few minutes to set if you have time. Otherwise proceed.
Soften the cookie butter and caramel sauces in the microwave for a few seconds. If you don't have a microwave, you can set the jars in a pan of simmering water or hot tap water for a few minutes to make the spread/sauce easier to work with.
Using a sharp knife, slice the carton of ice cream halfway through vertically. Remove carton from the sides and immediately cut each half into three slices.
Place three of the slices across the bottom of the pan and smooth quickly with a spatula.
Spread a thick layer of cookie butter all over the first layer of ice cream. You'll almost or likely use the whole jar. Just do it.
Working quickly, layer the rest of the ice cream on top of the cookie butter.
Next, pour over the caramel sauce.
Spread the whipped topping over top of the caramel. Crumble the remaining four cookies and sprinkle over top of the ice cream.
Immediately put in the freezer for at least 4-6 hours or overnight.
When ready to serve, remove from freezer for about 5-10 minutes and lift out of the pan. Slice using a sharp knife. You can also dip the knife in warm water in between slicing.
