Wash, hull, and dry the strawberries thoroughly.
Slice the strawberries and place them in a large bowl.
Add sugar and lemon juice, then mix well.
Cover and let sit at room temperature for 1 hour to release juices.
In another bowl, whip the heavy cream with powdered sugar and vanilla until stiff peaks form.
Transfer whipped cream into a piping bag or keep it ready with a spoon.
To assemble the No Bake Strawberry Dessert Cups, layer macerated strawberries and whipped cream in serving cups.
Garnish with fresh strawberries and mint if desired. Serve immediately or chilled.
