Preheat the oven to 400°F (200°C).
In a mixing bowl, combine flour, sugar, baking powder, and salt.
Add the cold, cubed butter and mix until the mixture becomes crumbly.
Pour in the heavy cream and stir until the dough comes together.
Turn the dough onto a floured surface, kneading gently.
Roll the dough to 1-inch thickness and cut into rounds.
Arrange the rounds on a baking sheet and bake for 15 to 20 minutes until golden.
While the shortcakes bake, toss the sliced strawberries with sugar and let them sit to macerate.
Once cooled, slice the shortcakes in half horizontally.
Layer the bottom halves with macerated strawberries and whipped cream.
Place the top halves over the layers and add more whipped cream on top before serving.
