• Serves: 12
• Yields: 12 scones

Ingredients

• 3  cups all-purpose flour
• 1⁄3 cup  packed golden brown sugar
• 1  tablespoon baking powder
• 1  teaspoon baking powder
• 1 1⁄2 teaspoons baking soda
• 3⁄4 teaspoon  coarse kosher salt
• 11  tablespoons  chilled unsalted butter, cut into 1/2 inch cubes
• 1  cup old fashioned oats
• 3  tablespoons old fashioned oats
• 1  cup fresh blueberries
• 1 3⁄4 cups  chilled half-and-half
• 1  teaspoon vanilla extract
• 5  teaspoons turbinado sugar

Directions

1. Position 1 rack in top third and 1 rack in bottom third of oven and preheat to 350 degrees. Lined rimmed baking sheets with parchment paper.
2. Combine flour, brown sugar, baking powder, baking soda, and coarse salt in processor; blend 5 seconds. Add butter. Using on/off turns, blend until mixture resembles coarse meal. Transfer mixture to a large bowl. Add one cup oats and blueberries; stir to blend evenly.
3. Stir half and half and vanilla in small bowl. Gradually add to flour mixture, tossing until dough just comes together (dough will be very moist).
4. Using 1/2 cup measuring cup for each scone, drop dough in mounds onto prepared baking sheets, spacing 3 inches apart. Sprinkle tops with remaining 3 tablespoons oats, then raw sugar.
5. Bake 15 minutes. Reverse sheets and continue baking until scones are golden and tester inserted from side comes out clean, about 12 minutes longer. Transfer scones to a rack and cool slightly. Serve warm or at room temperature.
