In a medium bowl, combine the sliced strawberries and sugar. Toss together and let the mixture sit for about 15 minutes to macerate and release juices.
In a mixing bowl, whip the heavy cream until soft peaks form. Gradually add the powdered sugar and vanilla extract, continuing to whip until stiff peaks form.
Prepare your serving glasses or trifle bowl. Begin layering by placing a layer of pound cake cubes at the bottom.
Add a layer of the macerated strawberries over the pound cake.
Follow with a layer of yogurt, spreading evenly.
Next, add a generous layer of the whipped cream on top of the yogurt.
Repeat the layers until the glasses or bowl are filled, ending with whipped cream on top.
Garnish with a few extra strawberry slices and fresh mint leaves for presentation.
