Preheat oven to 400°. Line a baking sheet with parchment paper.
Cut butter into small cubes and freeze for 10 minutes.
In the work bowl of a food processor, pulse together sugar and lemon zest. Add flour, baking powder, and salt, pulsing 4 to 5 times to combine. Add frozen butter, pulsing 4 to 5 times until it looks like cornmeal.
In a small bowl, whisk together sour cream, egg, and vanilla extract until smooth. Add to flour mixture, pulsing a few times until a dough begins to form.
Transfer mixture to a large bowl and gently fold in raspberries. (This will be a firm dough, and the raspberries may break up a little. That’s okay.) Shape dough into a ball.
On lightly floured parchment paper, pat dough into a 7-inch (approximately ¾-inch-thick) circle. (If scones are too thin, they will be a little firmer and not as fluffy.) Using a large, wet knife, cut dough into 8 wedges. Place wedges 2 inches apart on prepared baking sheet.
Bake until golden, 15 to 17 minutes. Let cool for 20 minutes.
In a medium bowl, stir together melted butter, confectioners’ sugar, and lemon juice until smooth. (If the mixture is too thin, add more confectioners’ sugar. If it is too firm, add 1 tablespoon water.) Drizzle glaze over scones.
