Preheat oven to 425F (220C). Line a baking sheet with parchment paper.
In a large bowl, whisk together flour, granulated sugar, baking powder, and salt.
Cut in cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
Stir in heavy cream and vanilla extract until just combined. Do not overmix.
Gently fold in 1/2 cup of the freeze-dried strawberries, coarsely crushed.
Drop dough by rounded spoonfuls onto the prepared baking sheet.
Brush the tops of the shortcakes with heavy cream.
Bake for 20-25 minutes, or until golden brown.
While the shortcakes are baking, prepare the whipped cream topping. In a large bowl, whip heavy cream, powdered sugar, and vanilla extract until stiff peaks form.
Gently crush remaining 1/2 cup freeze-dried strawberries for garnish.
To assemble, split warm shortcakes in half. Spoon whipped cream over the bottom half, top with crushed freeze-dried strawberries, and cover with the top half of the shortcake. Serve immediately.
Tips and Substitutions:
For a richer flavor, use buttermilk instead of heavy cream in the shortcake dough.
Gluten-free flour blend can be used as a substitution for all-purpose flour for a gluten-free version.
Vegan butter and cream substitutes may be used to accommodate a vegan diet. The taste and texture will vary from the original recipe.
Rehydrate some freeze-dried strawberries with a touch of warm water or lemon juice for a saucier topping.
