For the crust, preheat oven to 350 degrees F. Place crushed cookies, sugar, and butter in a large bowl. Stir until combine. Press the mixture into the bottom and up the sides of a 10" springform pan. Bake crust for 8-10 minutes or until firm and set. Let cool completely.

In a large bowl, stir together ice cream , Biscoff Spread, and Heath toffee bits. Spread the ice cream mixture evenly over the cooled cookie crust. Smooth out the top and sprinkle with chopped Biscoff cookies and Heath toffee bits. Freeze until firm, about 6 hours or overnight.

Remove cake from freezer and let sit for 5 minutes. Loosen pan sides and run a knife around the inside of pan. Carefully remove cake from pan and place on a serving platter. Cut cake into pieces, using a sharp knife. Serve immediately.

Note-I use our food processor to crush the cookies for the crust. If the cake is hard to cut, run your knife under hot water and then cut. Look for Biscoff Spread by the peanut butter. You can find the cookies in the cookie aisle. You can also order them from Amazon. If you can't find Biscoff Spread, you can use Trader Joe's Cookie Butter.
