Cover the cake with plastic wrap and place in freezer for about 30 minutes.
Let ice cream stand at room temperature for about 20 minutes.
Slice frozen cake horizontally into 4 equal layers (using a bread knife). Place bottom cake layer on desired serving plate. Spread layer with vanilla ice cream, leaving a ½ inch border around the edge. Top with the second cake layer and repeat layers with strawberry ice cream, cake layer, chocolate and remaining cake layer.
Wrap the cake in plastic wrap and freeze at least 8 hours, or overnight.
FROSTING
Beat the whipping cream on high speed until foamy. Gradually add sugar and vanilla, beating until stiff peaks form.
Remove the cake from freezer and spread frosting on cake. Sprinkle with almonds. Slice to serve, freezing any leftovers.
