Lemon Cake with Macerated Berries

Ingredients:
1 Lemon Cake Mix, already made and baked in 9"rounds
Cool Whip
1 clamshell of blueberries
1 clamshell of strawberries, sliced
1/2-full cup of sugar

Rinse the berries, and mix with sugar, until there's a good covering of sugar on the berries. Mash the strawberries about halfway and refrigerate for at least an hour.
Ice one cake with a little under 1/2 the Cool Whip and top with 1/2 the berry mix. Add a little cool whip on top to keep the berries in place. Set the other cake on top and ice with the remaining Cool Whip. Add the remaining berries on top and press them down a bit to keep them from sliding around. Refrigerate.
