Using a box grater, grate butter and return to the fridge to chill while preparing other ingredients.
Preheat oven to 400 degrees. Line a baking sheet with silicon baking mat or sheet of parchment paper.
In a large bowl, whisk together the flour, sugar, baking powder, and salt. Set aside.
Mix together milk and vanilla extract. Set aside.
Using your hands or a pastry cutter, gently add the grated butter and work the mixture evenly.
Make a well in the center and pour in the milk/vanilla mixture. Using a fork or your hands, mix until ingredients are incorporated, but still rough and shaggy. ***It is important not to overwork the dough.
Gently fold in the chopped strawberries. If the dough seems too dry, add in 1-2 tablespoons more milk, but note that the strawberries will help add more juices to the dough. If your dough is sticking to your hands, you need more flour.
Flour a flat surface and pat the dough into 3/4-inch thick round. Cut into wedges. Transfer to the prepared baking sheet, spacing 1 inch apart.
Brush the tops with heavy cream and sprinkle with sugar crystals before baking.
Bake until light brown, about 18-20 min. Transfer to a cooling rack for about 5 min.
Once cool, in a small bowl, mix together powder sugar, vanilla and milk. Drizzle over scones. Let harden for 5-10min and then serve!!
Notes
1. Grated butter makes it easier to incorporate into the dough.
