In a medium saucepan, combine the mixed berries, granulated sugar, and lemon juice.
Place the saucepan over medium heat and bring the mixture to a simmer, stirring occasionally.
Simmer for about 5 to 7 minutes or until the berries are soft and the mixture has thickened slightly.
In a small bowl, whisk together the cornstarch and water until smooth.
Pour the cornstarch slurry into the simmering berry mixture and stir constantly until the sauce thickens, about 1 to 2 minutes.
Remove the saucepan from the heat and let the berry sauce cool completely.
In a large bowl, beat the softened cream cheese with an electric mixer until smooth and creamy. Gradually add the powdered sugar, beating until well combined.
Stir in the vanilla extract.
Gently fold in the thawed whipped topping until just combined.
In a 9×13 inch baking dish, dip each vanilla wafer or graham cracker piece in milk or juice before layering.
Arrange a single layer of wafers on the bottom of the baking dish.
Spread half of the cream cheese filling evenly over the wafer layer.
Spoon half of the cooled berry sauce over the cream cheese filling and spread it evenly.
Arrange another layer of wafers over the berry sauce.
Spread the remaining cream cheese filling evenly over the wafer layer.
Spoon the remaining berry sauce over the cream cheese filling and spread it evenly.
Cover the lasagna with plastic wrap and refrigerate for at least 4 hours or overnight.
Before serving, garnish with fresh berries, mint leaves, and a dusting of powdered sugar.
Cut the lasagna into squares and serve chilled.

Notes
Ensure to soften the cream cheese fully for a silkier filling. You can also use graham crackers or shortbread cookies if you don’t have vanilla wafers.
