Slice the lemon pound cake lengthwise into 4 even slices.
Line a loaf pan with plastic wrap or parchment paper. Make sure there's enough plastic wrap along the edges of the pan to wrap over the top of the cake.
Lay down the first layer of cake, followed by ~1/3rd of the vanilla ice cream. Repeat this layering twice, placing the final layer of cake on top.
Wrap the excess plastic wrap over the top of the cake and freeze for at least 4-6 hours.
Remove the cake from the freezer and plastic wrap, place on a platter, and quickly ice the cake with the whipped topping. Serve immediately garnished with fresh fruit, or place back in the freezer (uncovered) until it's time to enjoy!
