01 - Preheat the 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 well combined.
03 - Add the cold, cubed butter to the flour mixture. Using a pastry cutter or your fingertips, work the butter into the flour until the mixture resembles coarse crumbs with some pea-sized pieces remaining.
04 - In a separate bowl, whisk together cream, egg, and vanilla extract until fully blended.
05 - Pour the wet ingredients into the dry ingredients. Mix gently with a spatula or wooden spoon until just combined. The dough will be slightly shaggy. Do not overmix.
06 - Gently fold in the diced strawberries until evenly distributed throughout the dough.
07 - Turn the dough onto a lightly floured surface. Gently pat into a 1-inch-thick circle, approximately 7 inches in diameter. Handle the dough minimally to keep it tender.
08 - Cut the circle into 8 equal wedges using a sharp knife or bench scraper. Transfer the wedges to the prepared baking sheet, spacing them 2 inches apart.
09 - Brush the tops of each scone with a thin layer of cream. Sprinkle generously with coarse sugar for a crunchy top.
10 - Bake for 16 to 18 minutes, or until the tops are golden brown and a toothpick inserted into the center comes out clean.
11 - Let the scones cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely for at least 10 minutes before serving.
