Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.

In a mixing bowl, whisk together the flour, baking powder, sugar, and salt.

Add the cold, cubed butter to the flour mixture and use a pastry cutter to blend until the mixture resembles coarse crumbs.

Stir in the diced strawberries.

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

Turn the dough out onto a floured surface and gently knead it a few times until it comes together.

Pat the dough into a circle about 1 inch thick and cut into wedges or use a round cutter to shape scones.

Place the scones on the prepared baking sheet and bake for 15-20 minutes or until golden brown.

Let cool slightly before serving.
