Follow directions for pound cake recipe. When cooled, cut a few slices (about 1 inch thick) & cut into cubes or desired sized pieces.
In a small bowl, combine berries & a few shots of limoncello. If you don't want to use limoncello or can't find it, I'm sure a few tablespoons of lemonade concentrate diluted with a little water would probably have the same effect, though your berries won't really be "drunken" if you take this approach. ;) Let berries "marinate" in the refrigerator (when we're talking fruit it's actually called mascerating, but who needs to be all fancy?) for up to a few hours.
In a dessert cup or other pretty vessel (martini glass would be nice!), place a few pieces of cubed pound cake.
Spoon berries over pound cake, making sure you get some of the limoncello from the bottom of the bowl for it to soak up into the cake.
Top with whipped cream.
