Step 1: Prepare the Dry Ingredients

Start by whisking together the dry ingredients. In a large mixing bowl, combine the flour, sugar, baking powder, and salt. This step ensures that the dry ingredients are evenly distributed throughout the dough, which is crucial for achieving consistent texture and flavor in the scones.

Step 2: Cut in the Cold Butter

Next, add the cold butter to the dry ingredients. It’s important that the butter is cold—this is what creates those signature flaky layers. You can use a pastry cutter, two forks, or even your hands to work the butter into the flour mixture. The goal is to cut the butter into the flour until the mixture resembles coarse crumbs with pea-sized pieces of butter. The butter will melt slowly as the scones bake, creating tender layers throughout the dough.

Step 3: Add the Wet Ingredients

Once the butter is fully incorporated, add the buttermilk, vanilla extract, and lemon zest to the mixture. Gently stir with a spatula or spoon until the dough begins to come together. Be careful not to overwork the dough, as this can result in dense scones. It’s okay if the dough is a little sticky—this will help create the tender, moist texture of the scones.

Step 4: Fold in the Blueberries

Once the dough is mostly combined, fold in the blueberries. This can be a delicate step, as you want to avoid mashing the berries. Gently stir the blueberries into the dough until they are evenly distributed. Fresh blueberries work best for this recipe, as they hold their shape and provide bursts of sweetness in each bite.

Step 5: Shape the Dough and Chill

Turn the dough out onto a lightly floured surface and gently shape it into a disc about 1-inch thick. Use a sharp knife or a bench scraper to cut the disc into 8 wedges, like a pizza. Place the scone wedges onto a parchment-lined baking sheet, spacing them out a little to allow for even baking. To ensure that your scones bake up light and flaky, it’s important to chill the dough for about 15 minutes before baking. This helps maintain the cold temperature of the butter and ensures the scones rise properly.

Step 6: Brush with Buttermilk

Before baking, brush the tops of the scones with a little buttermilk. This helps the scones achieve a golden, slightly crisp exterior. The buttermilk also adds a touch of richness to the scones’ flavor, making them even more irresistible.

Step 7: Bake Until Golden

Preheat your oven to 400°F (200°C) and bake the scones for about 15-20 minutes, or until they are lightly golden brown on top. You’ll know they are done when a toothpick inserted into the center of a scone comes out clean. The scones should be tender, slightly crumbly on the inside, and golden brown on the outside.

Step 8: Prepare the Buttermilk Glaze

While the scones are baking, prepare the buttermilk glaze by whisking together the powdered sugar, buttermilk, and vanilla extract in a small bowl. The glaze should be smooth and slightly runny—perfect for drizzling over the warm scones.

Step 9: Glaze the Scones

Once the scones have cooled for a few minutes, drizzle the buttermilk glaze generously over the top of each scone. Allow the glaze to set for a few minutes before serving. The glaze will harden slightly, giving the scones a sweet, glossy finish.
