Place cake on board or heavy foil. With electric knife, slice a layer of cake about 1 inch from top; set aside. Make a hollow in cake by cutting down into it 1 inch from the outer edge and 1 inch from the middle hole, leaving a substantial 1-inch base on bottom of cake. Remove excess cake to form a cavity. Spoon ice cream into cavity in cake; replace top of cake and press down against ice cream. Wrap cake in foil and freeze until firm but not hard (about 2 hours). Whip cream until soft peaks form. Add sugar, whipping until stiff. Frost top and sides of cake with sweetened whipped cream. Garnish with pecans. Freeze for at least 1/2 hour longer. Cut into wedges with electric knife.
