Instructions
Preheat oven to 425°F. Line a baking sheet with parchment paper.
In a food processor, combine 2 cups(280g) gluten-free flour blend, 1/2 cup(100g) granulated sugar, 1 tablespoon baking powder, 1/2 teaspoon ground cinnamon, and 1/2 teaspoon salt. Pulse to combine.
Add 6 tablespoons(84g) unsalted butter and pulse 10-15 times, until butter is pea-sized. Do not over mix. Transfer the flour mixture to a large bowl.
Add 1 teaspoon vanilla extract and 1/2 cup(122g) whole milk. Fold with a spatula until dough just comes together. If too dry, add more milk 1 tablespoon at a time. Dough should hold together but not be wet.
Gently fold in 1 cup(148g) fresh blueberries, trying to ensure they do not break.
Transfer the dough to a generously floured work surface. Knead the dough into a ball. Shape into a 7-inch circle, about 1 inch thick.
Cut into 8 wedges with a floured knife.
Transfer to prepared baking sheet. Brush tops with 1 tablespoon(14g) unsalted butter and sprinkle with 1 teaspoon turbinado sugar.
Bake at 425°F for 18-22 minutes, until tops and bottoms are golden brown.
Cool on a wire rack for 5 minutes before serving.
Notes
Measuring flour: Weigh it if you can. If not, spoon flour into your measuring cup and level off with a knife. Scooping from the bag packs it down and makes dense scones.
Frozen blueberries: Toss with a tablespoon of flour before folding in to reduce bleeding.
Storage: Freeze baked scones for up to 2 months. Reheat from frozen at 350°F for 10-15 minutes.
