Butter gives these scones a flaky crust and sour cream helps with the moist interior. Use chocolate chips or switch things up and add your favorite berries.
Mix flour, both sugars, baking powder, baking soda and salt together in a mixing bowl.
Grate the cold butter into the flour mixture, tossing gently to distribute it evenly, then stir until mixture is coarse and flour is coated with fat. Alternatively, just cut the butter into bits and use your fingers or a pastry cutter to do this.
In a small bowl, whisk egg, sour cream and vanilla until smooth. Stir sour cream mixture into flour mixture gradually until large dough clumps form. Add the chips.
When dough just starts to come together, turn it onto a clean surface and shape it into a 7 inch circle. If you prefer, you can make 2 rectangles. Slice the circle into 8 triangles or slice each rectangle into 4 triangles. Arrange triangles a few inches apart on a cookie sheet.
I usually make 8 scones. Note that if you make them larger (6 scones) they will need more time to bake.
Bake until golden, about 15 to 17 minutes (could take longer in some ovens). Cool for at least 5 minutes and serve warm or at room temperature. This recipe makes 6 to 8 scones.
