1 cup all-purpose flour
¾ cup whole wheat flour
¼ cup quick cooking oats
1/3 cup sugar
2 teaspoons baking powder
½ teaspoon baking soda
1/8 teaspoon salt
2 tablespoons butter
1 teaspoon pure vanilla extract
¾ cup skim milk + 1 teaspoon white vinegar
1 teaspoon finely grated lemon zest
1 cup blackberries
2 tablespoons milk mixed with ¼ teaspoon pure vanilla extract
1 tablespoon sugar
1) Preheat oven to 400 degrees Fahrenheit and line a baking sheet with parchment.
2) Whisk together flours, oats, sugar, baking powder, baking powder and salt. Cut in the butter until it is incorporated. Stir in the milk and vinegar, egg, vanilla, and lemon zest, and mix just until combined. Fold in blackberries.
3) Turn the dough out onto a lightly floured surface and form into an 8 inch in diameter circle. Pat down slightly so it is just over an inch thick, and cut into 8 evenly sized wedges. Transfer the wedges onto a baking sheet and brush with the milk and vanilla mixture, and then sprinkle with sugar. Bake for about 20 minutes, or until scones are evenly golden brown.
