Creating the No Bake Summer Berry Icebox Cake is simple if you follow these easy steps:

1. Prepare the Cream Mixture: In a mixing bowl, combine the heavy whipping cream, mascarpone cheese, powdered sugar, and vanilla extract. Whip until soft peaks form.
2. Prepare the Berries: Wash and gently pat dry the mixed fresh berries. If using strawberries, slice them into halves or quarters.
3. Layer the Cake:
– Start by spreading a thin layer of the cream mixture at the bottom of an 8×8 inch square dish.
– Place a layer of graham crackers or ladyfinger cookies on top.
– Add a layer of mixed berries over the cookies.
– Repeat the layers until all the ingredients are used, finishing with a layer of the cream mixture on top.
4. Chill the Cake: Cover the dish with plastic wrap and refrigerate for at least 4 hours, preferably overnight. This chilling time allows the layers to set beautifully.
5. Serve: Once chilled, slice the cake into squares and garnish with additional fresh berries and mint leaves if desired.
