Preparation Steps

• Preheat the oven to 400°F.
• In a large bowl, mix all the dry ingredients: flour, sugar, salt, baking soda, and baking powder.
• Using the large holes of a cheese grater, grate the frozen butter into the flour mixture. Mix well with your fingers or a pastry blender until the butter is evenly distributed and resembles coarse crumbs.
• In a separate medium bowl, whisk together the buttermilk, large egg, and vanilla extract.
• Pour the wet ingredients into the dry ingredients. Using a fork, slowly stir until all the mixture is just moistened. Do not overwork the dough.
• Gently fold in the fresh blueberries.
• Line a baking sheet with parchment paper or a silicone baking mat. Drop large spoonfuls of the dough onto the prepared baking sheet. Avoid pressing or compacting the dough to ensure tender scones.
• Bake in the center rack of the preheated oven for 18-20 minutes, or until golden brown and cooked through. Let them cool on the baking sheet for about 5 minutes before serving.
