Whisk together all chai spices with brown sugar. Set aside.
Crescents
Preheat oven to 350 F. Line a baking sheet with parchment paper.
In a bowl, whisk together flour, sugar, baking powder & salt. With a pastry blender, cut in cream cheese & shortening until mixture resembles coarse peas. Stir in milk. On a lightly floured work surface, knead dough gently about 20 times.
Form dough in a ball then roll out into a 14-inch circumference. Spread butter over the surface of dough then spread spice/sugar combo (all but 1 tsp needed for drizzle) evenly over the butter.
Cut circle into 12-14 equal wedges. Roll each wedge from the outside edge to form a crescent shape. Slightly curve each one & place on baking sheet.
Bake for about 20 minutes or until pastry is baked. Remove from oven & place on wire cooling rack.
Drizzle
In a small bowl, beat together cream cheese & butter until smooth. Add 1/2 tsp chai spice mix, powdered sugar, salt & vanilla. Beat until well combined then add enough milk to make a drizzle consistency. When crescents are cool, drizzle & serve.
