01 - Beat softened cream cheese in a medium bowl until completely smooth. Add powdered sugar and vanilla extract, continuing to beat until fully incorporated. Gently fold in whipped topping until mixture achieves creamy, uniform consistency.
02 - Evenly distribute a layer of crushed shortbread cookies across the bottom of a glass trifle bowl or individual serving cups.
03 - Spread a generous layer of the whipped cheese mixture over the cookie base, ensuring even coverage.
04 - Arrange sliced strawberries and blueberries over the cream filling, distributing them evenly for visual appeal.
05 - Continue layering in sequence: crushed cookies, whipped filling, mixed berries. Repeat until all ingredients are used, ensuring the final layer consists of fresh berries on top.
06 - Top with additional fresh berries and mint leaves if desired. Refrigerate for at least 1 hour to allow flavors to meld and layers to set before serving.
