Place the 2 cups of flour, sugar, baking powder and kosher salt into the bowl of a stand mixer. Using low speed mix until blended together about 15 to 20 seconds.
Toss the pieces of cold butter in with the flour mixture. Still using low speed, blend the butter into the flour until it is in small pieces, about the size of peas, 3 to 4 minutes. It’s okay if there are some larger pieces.
Whisk together the 2 eggs with ¾ cup of cream, orange zest and orange extract.
Pour the cream and eggs into the flour mixture. On low speed, blend until the cream and eggs are mixed into the flour and the dough has just come together, about 1 minute. The dough will be somewhat sticky but don’t over mix or the scones will be tough.
Dust the dried cranberries and the toasted walnuts with the extra tablespoon of flour. Add to the dough, blending in on low speed, about 20 to 30 seconds.
Turn the dough out onto a large surface that has been dusted with flour. Sprinkle a small amount of flour over the top and gently gather the dough together and divide into two pieces
Pat each into a round, about 1” thick. Using a sharp knife, cut each round into six wedges, dusting the knife with flour between cuts to prevent it from sticking.
Place the scones on a large baking sheet, lined with either parchment paper or a Silpat liner.
Whisk together the 2 tablespoons of cream with the remaining egg. Lightly brush the top of each scone with the egg wash. Sprinkle the tops of each scone with the remaining 2 teaspoons of sugar.
Bake in a preheated 425-degree oven for 12 to 14 minutes or until golden in color.
Serve warm or at room temperature. To reheat, place the scones on a baking sheet and pop in a 350-degree oven for 5 to 6 minutes.
