Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a large bowl whisk flour, sugar, baking powder, and salt.
Add cold butter and cut it into the flour mixture until crumbly.
Gently fold in chopped strawberries.
In another bowl whisk cream, egg, and vanilla extract.
Pour wet ingredients into dry mixture and stir until a soft dough forms.
Turn dough onto a floured surface and shape into a round disc.
Cut the dough into 12 triangle wedges.
Place scones on the baking sheet and brush tops with milk.
Sprinkle coarse sugar on top for a bakery-style finish.
Bake for 16–18 minutes until golden brown.
Cool slightly before serving warm.
