01 - Beat cream cheese in medium bowl until smooth. Add powdered sugar and vanilla extract, beat until fully incorporated. Gently fold in whipped topping until mixture is creamy and smooth throughout.
02 - Sprinkle an even layer of crushed shortbread cookies across the bottom of a glass trifle bowl or individual serving cups, pressing gently to create a stable foundation.
03 - Spread a generous layer of the whipped cheese mixture over the cookie base, ensuring complete coverage and maintaining an even thickness.
04 - Distribute sliced strawberries and blueberries evenly across the filling layer, pressing lightly to anchor them in place.
05 - Repeat the layering sequence—cookies, whipped filling, mixed berries—until all components are used. Conclude with a vibrant berry topping for visual appeal.
06 - Top with additional berries and fresh mint leaves if desired. Refrigerate for at least 1 hour to allow flavors to meld and layers to set before serving.
