Preheat your oven to 400°F (200°C). In a large bowl, mix flour with cold butter until it resembles coarse crumbs.

Gradually add ice-cold water until the dough comes together; avoid overworking it.

Roll out dough on a floured surface to about 1/4 inch thick and cut into 3-inch circles.

Place on a baking sheet lined with parchment paper and bake for 15-20 minutes until golden brown. Let cool completely on a wire rack.

While cooling, whip heavy cream with powdered sugar until soft peaks form; fold in diced strawberries gently.

Slice each pastry in half horizontally, fill with strawberry whipped cream, and cap with the top half.
