Preheat oven to 425°F (220°C).
In a large bowl, whisk together flour, baking powder, and salt. Cut in cold butter using a pastry blender or your fingers until mixture resembles coarse crumbs.
Stir in milk until just combined. Do not overmix.
Drop spoonfuls of dough onto a baking sheet lined with parchment paper.
Bake for 15-20 minutes, or until golden brown.
While biscuits are baking, gently toss strawberries with sugar.
Whip heavy cream until stiff peaks form.
To assemble, split each biscuit in half. Spoon strawberries and whipped cream over bottom half, then top with the other half of the biscuit.
