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.
03 - Add cold butter and use a pastry cutter or fingers to rub it into the flour until the mixture resembles coarse crumbs.
04 - In a small bowl, whisk together cream, egg, and vanilla. Pour over the flour mixture and stir gently until just combined.
05 - Gently fold in the strawberries, taking care not to overmix.
06 - Turn the dough onto a lightly floured surface and pat into a 1-inch-thick round. Cut into 8 wedges and transfer to the prepared baking sheet.
07 - Brush tops with a little extra cream and sprinkle with coarse sugar if desired.
08 - Bake 16–18 minutes, or until golden and cooked through. Cool slightly on a wire rack before serving.
