Line a large, rimmed baking sheet with parchment paper or a non-stick baking mat. Set aside.
Mix the 2 cups of flour, baking powder, sugar, and salt in a large mixing bowl.
Cut in the butter with a fork until butter is in pea-sized pieces.
In a separate bowl, combine the heavy cream, sour cream, egg, vanilla extract, orange extract, and orange zest. Whisk to combine.
Fold the wet ingredients into the dry ingredients until just combined.
Stir in the craisins until just mixed.
Sprinkle ¼ cup of flour onto a clean work surface.
Transfer the scone batter onto the floured surface and lightly knead into a ball.
Press the dough down into a ½”/1cm high rectangle (approximately 6” x 10”/15cm x 25cm).
Cut in half lengthwise, and then each half into 3 rectangles.
Then, cut each rectangle diagonally to create triangle-shaped pieces.
Transfer the scones to the prepared baking sheet, leaving 1-2”/2.5-5cm between them. Refrigerate for at least 30 minutes before baking.
Preheat oven to 200C/400F/Gas 6, then place the scones in the oven to bake for 18-22 minutes, or until they are nicely golden brown and cooked through. Remove from oven and cool for 5-10 minutes.
While the scones are cooling, prepare the orange glaze by stirring the powdered sugar and orange juice together in a small bowl until thoroughly combined.
Serve the scones warm drizzled with some of the orange glaze on top.
Enjoy and Happy Holidays!
