A no-bake frozen layered dessert that combines crunchy Oreo cookies, creamy chocolate and vanilla ice cream, buttery pecans, chocolate chips, and caramel. It looks impressive but comes together with simple ingredients and can be prepared ahead.
Let the chocolate and vanilla ice cream sit at room temperature for about fifteen minutes before spreading. Do not let the ice cream melt completely, or the layers will become watery and icy when refrozen. Use an offset spatula dipped in warm water to smooth each layer quickly. For clean edges, line the inside of the springform pan with parchment paper before pressing in the crust. Store leftovers tightly wrapped in the freezer for up to one week. Let the cake stand at room temperature for five to ten minutes before slicing.
