No Bake Mixed Summer Berry Icebox Cake is the perfect easy dessert for potlucks, barbecues, cookouts, picnics, baby showers, or any Fourth of July or Memorial Day party with the red, white and blue theme. Best of all, instead of triple, it’s got four berries – strawberries, blackberries, blueberries and raspberries with 10 minutes of prep time containing fresh whipped cream, cream cheese & graham crackers.
