Preheat the oven to 400°F, line a baking sheet with parchment paper and set aside.
In a standing mixer, using a paddle attachment, add all dry ingredients (all-purpose flour, granulated sugar, baking powder, and salt) and cold butter cut into chunks. Mix it on low speed for a few minutes until you have coarse pea-size crumbs.
Add dries cranberries and mix it until they are evenly distributed and fully covered with flour mixture.
In a medium mixing bowl, add wet ingredients (an egg, heavy cream, and orange zest). Mix it and add to the dry ingredients. On a low speed, mix it until just incorporated.
Take the dough and put it on a floured surface. Roughly knead it until it all comes together and put it in a round disk shape about 1 inch thick. Cut it into 8 equal edges and put on a baking sheet.
Brush the tops and the sides with egg wash (1 egg and ½ tablespoon of water beaten together). Sprinkle granulated sugar on top.
Bake at 400°F for about 15-17 minutes until the scones have beautiful golden color. When done, let it cool off completely.
For the Orange Glaze, mix powdered sugar with orange zest. Gradually add orange juice until the glaze is the right consistency. Drizzle it over the scones. Enjoy!
