01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt.
03 - Add the cold, cubed unsalted butter to the dry ingredients. Using a pastry cutter or your fingertips, cut the butter into the flour mixture until it resembles coarse crumbs.
04 - In a separate small bowl, whisk together the heavy cream, large egg, and pure vanilla extract.
05 - Pour the wet ingredient mixture over the dry ingredients. Mix just until combined, being careful not to overwork the dough.
06 - Gently fold in the fresh raspberries and white chocolate chips. Exercise caution to avoid crushing the berries.
07 - Turn the dough out onto a lightly floured surface. Pat it into a 1-inch thick circle. Using a sharp knife, cut the circle into 8 equal wedges and carefully transfer them to the prepared baking sheet.
08 - Lightly brush the tops of the scones with additional heavy cream. Bake for 16–18 minutes, or until the tops are golden brown.
09 - Allow the baked scones to cool slightly on the baking sheet before serving.
