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 well combined.
03 - Add cold butter cubes to flour mixture. Cut in with pastry blender or fingertips until mixture resembles coarse crumbs.
04 - In separate bowl, whisk together cream, egg, and vanilla extract until fully blended.
05 - Pour wet mixture over flour mixture. Stir gently until just combined; avoid overmixing to ensure tender scones.
06 - Gently fold in raspberries and white chocolate. Handle carefully to prevent crushing the berries.
07 - Turn dough onto lightly floured surface. Form into 7-inch round, about 1-inch thick.
08 - Cut round into 8 equal wedges. Place on prepared baking sheet, spacing apart for even baking.
09 - Brush tops with extra cream. Sprinkle with coarse sugar if desired for crunch and sweetness.
10 - Bake for 16-18 minutes until golden brown. Cool slightly on sheet before serving warm.
