Marinate 1 cup of frozen mixed berries with 2 1/2 tbsp. Amaretto. Let come to room temperature. Mash with a fork until lightly blended together, reserving 3 tbsp. crushed berries for topping.
Soften 14-oz. container of vanilla bean ice cream at room temp just enough to be stirred. Transfer to a large mixing bowl, add berries and 1/3 cup dark chocolate chips. Mix thoroughly with a mixing spoon (do not beat with mixer). Transfer ice cream back to the container and return to freezer for at least 4 hours.
Scoop ice cream into fancy bowls, top with crushed berries and chocolate chips.
