Preparation

• Preheat the oven to 400 degrees. Line a baking sheet with parchment paper or a silicone mat.
• In a large bowl, combine the flour, baking powder and salt. Add the butter, then use your fingers to rub the butter into the ingredients until the mixture is coarsely combined.
• Add ½ cup buttermilk, sugar, egg, chai spice mix and vanilla extract, then use a spatula or your hand to almost bring the mixture together. Add the chocolate chips and gently mix to combine, taking care not to overwork the dough.
• Sprinkle a clean work surface with flour and turn the dough out on it. Use your hands to forma 6-inch disk, then use a sharp knife to divide into 6 equal wedges.
• Place scones on the baking sheet with room between them to spread. Brush the scones with the remaining 1 tablespoon buttermilk and sprinkle with the coarse sugar.
• Bake 20 to 25 minutes, until lightly golden and cooked through. Let cool about 10 minutes before serving.
