Butterfinger Ice Cream Cake

1 brick vanilla ice cream
1 brick chocolate ice cream
1 pint cream, whipped
3 Butterfinger bars

Break up Butterfinger bars. This is easier to do if you freeze the candy bars first, then crush with a mallet. Cut ice cream into slabs. Layer 1 vanilla ice cream, then Butterfinger crumbs, then chocolate ice cream, then Butterfinger crumbs, then vanilla ice cream again. Top with whipped cream and Butterfinger crumbs. Put back into freezer until needed.
