In a medium bowl, combine the sliced strawberries, sugar, and lemon juice. Toss gently and let it sit for about 15 minutes to soften and release their juices.
In a separate bowl, whip the heavy cream with an electric mixer until it starts to thicken. Add in the powdered sugar and vanilla extract, and continue whipping until stiff peaks form.
In a large trifle dish or individual glasses, start layering your trifle. Begin with a layer of cubed pound cake at the bottom.
Follow with a layer of the strawberry mixture, ensuring some of the sweet strawberry juice coats the cake.
Add a layer of yogurt followed by a generous layer of whipped cream.
Repeat the layers (cake, strawberries, yogurt, whipped cream) until the trifle dish is filled, finishing with whipped cream on top.
Decorate the top with any remaining strawberry slices and a few fresh mint leaves for a pop of color.
Chill in the refrigerator for at least 1 hour before serving to let the flavors meld together.
Notes
Serve chilled, and consider using clear glass dishes to showcase the beautiful layers of this delightful trifle.
