Preheat the oven to 400°F and line a baking sheet with parchment paper.
Add flour, sugar, salt, and baking powder to a medium mixing bowl and mix to combine.
In a measuring cup, add egg and cream to fill one cup. Add vanilla extract and beat to combine.
Make a well in the middle of the flour mixture and pour in the liquid mixture. Fold with a spatula or wooden spoon until a wet dough forms.
Turn the dough out onto a lightly floured board, fold it over itself a few times, and shape into a circle about 1” thick. Cut into 8 scones.
Place the scones on the prepared baking sheet, brush the top and sides with extra cream, and sprinkle generously with turbinado sugar.
Bake for 19 - 20 minutes until golden brown. Remove from the oven and let cool completely on a wire rack.
Serve warm with clotted cream or butter and jam.
