1-First Step: Mise en Place. Measure all ingredients accurately. Cube 1/2 cup cold butter and chill it in the freezer for 15 minutes. Rinse 1 cup blueberries if fresh, or thaw slightly if frozen, then pat dry. Whisk together 1/2 cup heavy cream, 1 egg, and 1 tsp vanilla in a small bowl. Keep wet mixture cold. This prep ensures smooth assembly and prevents sogginess.

2-Second Step: Mix Dry Ingredients. In a large bowl, combine 2 cups all-purpose flour, 1/3 cup sugar, 1 tbsp baking powder, and 1/2 tsp salt. Stir with a fork to distribute evenly. Spoon flour into measuring cup and level off to avoid dense scones. This dry mix forms the flaky foundation.

3-Third Step: Cut in Butter. Add chilled butter cubes to dry ingredients. Use a pastry cutter, two forks, or fingers to work butter in until mixture resembles coarse crumbs with pea-sized butter pieces. Work quickly to keep butter cold. This step creates steam pockets for ultimate flakiness in your flaky blueberry scones.

4-Fourth Step: Add Blueberries. Gently fold in 1 cup blueberries. Toss berries in 1 tbsp flour first if they seem juicy to prevent bleeding. Use a spatula for light handling. Overmixing here leads to tough scones, so stop when berries are just distributed.

5-Fifth Step: Combine Wet and Dry. Pour cold wet mixture over dry. Stir with a fork until dough just comes together, forming a shaggy ball. Add 1-2 tsp extra cream if too dry. Turn onto a lightly floured surface. Pat gently into an 8-inch circle, about 3/4-inch thick. Avoid kneading to preserve tenderness.

6-Sixth Step: Shape and Cut. Use a sharp knife to cut dough into 8 wedges. Place wedges 2 inches apart on prepared baking sheet. Brush tops with extra cream for golden shine. For even baking, chill shaped scones 15 minutes if kitchen is warm.

7-Final Step: Bake and Serve. Bake at 400°F for 18-22 minutes until edges are golden and centers spring back. Cool on sheet 5 minutes, then transfer to wire rack. Serve warm plain or with clotted cream. Store leftovers as noted below. Enjoy your easy scones bursting with flavor!
