Preheat oven to 400F
Combine the flour, sugar, and baking powder in a mixing bowl.
Use a pastry cutter or two table knives to cut in the cold butter. Cutting in means to combine the butter with the flour mixture without melting the butter. You should end up with coarse crumbs. The butter bits will be small and well covered in flour.
Stir in the diced strawberries, make a small well in the flour mixture and set aside.
In a small bowl use a fork or whisk to lightly whisk together the eggs, ½ cup of heavy cream and vanilla. Add this wet mixture into the small well of the flour mixture in the mixing bowl. Use a mixing spoon to carefully combine the wet and dry ingredients. I find towards the end of mixing it is easier to use your well floured hands to bring the dough together into a ball.
Once the dough is together, place it on a heavily floured work surface. Using your hands press the dough into an even flat disk that is approximately ¾ to 1 inch thick.
Cut the dough disk into 8 even pieces.
Place pieces on a parchment lined baking sheet at least an inch apart.
Brush the tops of each scone with a little heavy cream or milk and sprinkle with the coarse sugar.
Bake in the oven for 20-25 minutes, until the tops are golden brown.
Transfer scones to a cooling rack and allow to cool for at least 10 minutes.
While scones are cooling combine the powdered sugar and heavy cream or milk to form the glaze. You can add a little more cream if it is too thick or a little more sugar if the glaze is too thin for your liking. When adding more cream just do a little bit at a time, because a few drops can go a long way.
Use a spoon to drizzle the glaze over the scones and serve.
