With an electric mixer, beat the cream mixture on low speed until frothy; increase speed to high and beat until stiff. Using a serrated knife, split cake into two horizontal layers. With the tines of a fork, remove a portion from the cut sides of the top and bottom layers to form a tunnel when the layers are place together. Frost entire cake with remaining whipped cream. Chill.
