Preparation

1. Preheat the oven to 400°F (200°C).
2. In a large bowl, mix together the dry ingredients: flour, sugar, baking powder, baking soda, salt, and chai spice.
3. Cut in the cold butter until the mixture resembles coarse crumbs with some pea-sized bits.
4. Stir in the cold milk or buttermilk and vanilla until the dough comes together.
5. Do not overmix; if too dry, add a splash more liquid.

Shaping and Baking

1. Turn the dough onto a lightly floured surface and bring it together gently with your hands.
2. Pat the dough into a circle about 1 inch thick for full-size scones, and cut into 8 wedges.
3. For mini scones, pat into a smaller circle and cut into 12 to 16 wedges.
4. Place scones on a baking sheet, making sure to leave space between them.
5. Bake for 20-25 minutes until golden brown on top and the bottoms are set.

Glazing

1. Let the scones cool for at least 10 minutes before glazing.
2. In a bowl, whisk powdered sugar with maple syrup, a splash of milk or cream, chai spice, and vanilla to form the glaze.
3. Drizzle over the cooled scones and let sit for a few minutes to set.
