01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt until well combined.
03 - Add cold butter cubes to the flour mixture. Cut in using a pastry cutter or fingertips until mixture resembles coarse crumbs with pea-sized butter pieces remaining.
04 - In a separate bowl, whisk together heavy cream, egg, and vanilla extract until fully incorporated.
05 - Pour wet ingredients into dry mixture. Stir gently with a spatula until just combined, being careful not to overmix.
06 - Add fresh raspberries and white chocolate chips. Gently fold to distribute evenly throughout the dough, accepting that some raspberries may break apart slightly.
07 - Turn dough out onto a lightly floured surface. Pat into an 8-inch circle about 1 inch thick. Cut into 8 equal wedges and transfer to the prepared baking sheet.
08 - Brush the tops of each scone with a small amount of extra heavy cream. Bake for 16-18 minutes or until golden brown. Cool on a wire rack.
09 - Whisk together powdered sugar, milk or cream, and vanilla extract until smooth and drizzling consistency is achieved. Drizzle generously over cooled scones.
