Preheat the oven to 425°F. In a large bowl, combine the flour, sugar, baking powder, and salt.

Cut in the cold butter using a pastry cutter or fork until the mixture resembles coarse crumbs.

Pour in the heavy cream and vanilla extract, and stir until just combined.

Drop spoonfuls of the batter onto a baking sheet lined with parchment paper and bake for 15-20 minutes until golden brown.

While the shortcakes are baking, prepare the strawberries by slicing them and sprinkling with a little sugar if desired.

Slice the baked shortcakes in half and assemble by layering strawberries and whipped cream. Serve immediately.
