01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together flour, sugar, baking powder, and salt until evenly distributed.
03 - Add cold butter cubes. Use a pastry cutter or your fingers to rub butter into the flour mixture until it resembles coarse crumbs with some pea-sized pieces remaining.
04 - In a small bowl, whisk together heavy cream, egg, and vanilla extract until fully combined.
05 - Pour the wet mixture over the flour mixture. Stir gently with a spatula or wooden spoon until just combined. Do not overmix.
06 - Gently fold in the chopped strawberries using a light folding motion to avoid crushing the fruit or overworking the dough.
07 - Turn dough onto a lightly floured surface. Pat gently into a 1-inch-thick round. Using a sharp knife or bench scraper, cut into 8 equal wedges and transfer to the prepared baking sheet.
08 - Brush the tops of each scone with a little extra heavy cream. Sprinkle generously with coarse sugar.
09 - Bake for 16 to 18 minutes until golden brown on top and cooked through. Cool on the baking sheet for 5 minutes, then transfer to a wire rack.
