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 thoroughly combined.
03 - Add cold cubed butter to the flour mixture. Use a pastry blender or fingertips to work butter into flour until mixture resembles coarse crumbs with some pea-sized pieces remaining.
04 - In a separate bowl, whisk together heavy cream, egg, and vanilla extract until fully incorporated.
05 - Pour wet mixture over flour mixture. Stir gently with a spatula or wooden spoon until just combined. Dough will be shaggy and slightly sticky. Do not overmix.
06 - Gently fold in raspberries and white chocolate chips, taking care not to crush the berries.
07 - Turn dough out onto a lightly floured surface. Gently pat into a 7-inch round disc, approximately 1-inch thick. Handle dough minimally to maintain tenderness.
08 - Cut disc into 8 equal wedges using a sharp knife or bench scraper. Transfer wedges to prepared baking sheet, leaving 2 inches of space between each scone.
09 - Brush tops with a small amount of heavy cream. Sprinkle with coarse sugar if desired. Bake for 16-18 minutes until golden brown on top and cooked through.
