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 blended.
03 - Add cold cubed butter to the flour mixture. Cut in using a pastry blender or fingertips 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 combined.
05 - Pour wet mixture over flour mixture. Stir gently with a spatula or wooden spoon until just combined. Do not overmix—some dry patches are acceptable.
06 - Gently fold in raspberries and white chocolate chips, taking care not to crush the berries. Mix only until evenly distributed.
07 - Turn dough onto a lightly floured surface. Pat gently into a 7-inch round, approximately 1-inch thick. Handle as little as possible to maintain tenderness.
08 - Cut round into 8 equal wedges using a sharp knife or bench scraper. Transfer wedges to prepared baking sheet, spacing 2 inches apart.
09 - Brush tops lightly with additional heavy cream. Sprinkle with coarse sugar if desired for a crunchy topping.
10 - Bake for 16-18 minutes until golden brown on top and a toothpick inserted into the center comes out clean. Cool on baking sheet for 5 minutes before transferring to wire rack.
