Heat oven to 400°F and line a baking sheet with parchment.
Whisk flour, sugar, baking powder, salt, and orange zest in a large bowl.
Cut in the cold butter until the mix looks like coarse crumbs with pea-sized bits.
Fold in the chopped cranberries to distribute evenly.
Stir vanilla into the cold cream, then pour over the dry mix and gently combine until just moistened.
Turn dough onto a lightly floured surface and pat into a 7–8 inch round, about 1 inch thick.
Cut into 8 wedges and move them to the prepared sheet, spacing slightly apart.
Brush tops with cream and sprinkle with turbinado sugar.
Bake 16–18 minutes, until golden at the edges. Cool on the pan 10 minutes before serving.
