01 - Cook the small pasta shapes in a large pot of salted boiling water until al dente. Drain thoroughly and rinse under cold water to halt the cooking process. Set aside to cool completely.
02 - In a medium bowl, dissolve the gelatin powder in boiling water, stirring until no granules remain. Incorporate the chilled fruity soda and stir to combine. Pour the mixture into a shallow dish and refrigerate for 1 to 1.5 hours, or until the gelatin is set but still yielding. Once the gelatin has reached a softly set state, gently cut it into small, bite-sized cubes.
03 - In a mixing bowl, beat the softened cream cheese until smooth and free of lumps. Incorporate the powdered sugar and vanilla extract, blending until well combined. Gradually introduce the heavy cream and continue beating until the mixture is light and fluffy in consistency.
04 - In a large mixing bowl, combine the cooled cooked pasta, the prepared gelatin cubes, half of the mixed berries, and the mini marshmallows (if using).
05 - Gently fold the cream cheese mixture into the pasta and gelatin blend, ensuring everything is evenly coated. Exercise care to maintain the integrity of the gelatin cubes.
06 - Spoon the assembled salad into individual parfait glasses or a communal serving bowl. Top with the remaining mixed berries and garnish with fresh mint leaves, if desired. Refrigerate the assembled salad for a minimum of 1 hour to allow the flavors to meld and harmonize before serving.
