In a medium bowl, combine the sliced strawberries with powdered sugar. Toss gently and let them sit for about 30 minutes to release their juices.
Preheat your oven to 425°F (220°C). In a large bowl, whisk together the flour, granulated sugar, baking powder, and salt.
Add the cubed butter to the flour mixture. Using a pastry cutter or your fingers, mix until the mixture resembles coarse crumbs.
Pour in the heavy cream and vanilla extract. Stir until just combined; do not overmix.
Turn the dough out onto a floured surface and gently knead a few times until it comes together. Pat the dough into a 1-inch thick rectangle. Use a round cutter (or a drinking glass) to cut out shortcakes and place them on a baking sheet lined with parchment paper.
Bake in the preheated oven for 12-15 minutes, or until the tops are golden brown. Remove from the oven and let them cool slightly on a wire rack.
In a separate bowl, whip the remaining heavy cream until soft peaks form. Optionally, you can sweeten it with a little powdered sugar to taste.
Slice the shortcakes in half horizontally. Spoon a generous amount of the macerated strawberries over the bottom half, followed by a dollop of whipped cream. Place the top half of the shortcake on top and add more strawberries and whipped cream if desired.
Garnish with fresh mint leaves for an extra pop of color and flavor.
Notes
For best results, use fresh strawberries and serve immediately after assembling.
