Our Cookie Butter Icebox Cake is the ultimate decadent no-bake dessert! Layer upon layer of rich, creamy cookie butter whipped cream and Lotus Biscoff cookies are piled high in a loaf pan, then refrigerated overnight. The magic happens as the cake chills and the cookies become soft and tender. This light as air cookie butter dessert will become a year-round staple. And it's a dream for making ahead!
