Bright lemon zest and juicy blueberries turn a basic weekend breakfast into something worth waking up for. These scones are tender on the inside with a craggy, golden top that catches just enough sugar to crunch. A quick lemon glaze on top ties the whole thing together.
Preheat oven to 400°F and line a half sheet baking pan with parchment paper.
Whisk together flour, granulated sugar, baking powder, baking soda, and salt in a large bowl until combined.
Cut cold cubed butter into flour mixture using pastry cutter until it looks like coarse crumbs with pea-sized butter pieces remaining.
Gently fold blueberries and lemon zest into the flour mixture, tossing lightly to coat the berries.
Whisk together heavy cream, egg, lemon juice, and vanilla in a separate bowl until smooth.
Pour wet into dry and fold gently with a spatula just until a shaggy dough forms. Avoid overmixing.
Turn dough onto a lightly floured surface and pat into an 8-inch circle about 1 inch thick.
Cut circle into 8 wedges and transfer to prepared pan, spacing 2 inches apart.
Brush tops with heavy cream and sprinkle generously with turbinado sugar.
Bake 16-18 minutes until golden brown and a toothpick inserted in center comes out clean.
Cool on pan for 5 minutes, then transfer to a wire rack. Whisk powdered sugar and lemon juice for glaze and drizzle over warm scones.
Notes
Keep everything cold: Cold butter and cream are essential for flaky scones. Chill your flour too if your kitchen runs warm.
Grate frozen butter: For even faster, flakier results, grate frozen butter instead of cubing it.
Don't overwork the dough: Mix just until the dough comes together. Overmixing develops gluten and makes scones tough.
Chill before baking: Refrigerate shaped wedges for 15 minutes before baking for taller, less spread out scones.
Fresh vs frozen berries: Use fresh when in season. If using frozen, keep them frozen and toss straight into the flour mixture to prevent bleeding.
Make ahead: Shape the wedges and refrigerate overnight, then bake straight from the fridge in the morning.
Freezing instructions: Freeze unbaked wedges on a tray, then transfer to a freezer bag for up to 3 months. Bake from frozen, adding 2-3 minutes to cook time.
Storage: Store unglazed scones in an airtight container at room temperature for up to 2 days. Glazed scones keep in the refrigerator for up to 4 days.
Reheating: Reheat in a 300°F oven for 8-10 minutes to restore crisp texture. Avoid microwaving as it makes the crust soft.
Variations: Swap blueberries for raspberries or blackberries, add 1/2 cup white chocolate chips, or use orange zest and juice instead of lemon for a citrus twist.
