Chai Gingerbread Cookies

1. To make the chai spice. In a shallow bowl, combine the cinnamon, ginger, cardamom, nutmeg, all-spice, cloves, and sugar in a glass jar or bowl. Set aside for sprinkling over the cookies. 
2. To make the cookies. In a large mixing bowl, cream together the butter and brown sugar. Add the molasses and vanilla, beat until light and fluffy, about 1 minute. Add the egg and mix until combined. Add the flour, baking soda, cinnamon, ginger, and salt, beat until combined and the dough forms a ball. If the dough feels too wet to roll out, add 2-4 tablespoons of additional flour.
3. Divide the dough in half. Roll out the dough on a floured piece of parchment to 1/4 inch thickness. Make sure you're using enough flour or your dough will stick. Cut out the cookies using gingerbread cookie cutters. Carefully transfer the cookies to a parchment-lined baking sheet. I recommend using a floured spatula to lift the cookies. Sprinkle each cookie with the chai sugar. Cover the baking sheet and place in the freezer. Freeze until firm, about 20-30 minutes. Roll out the leftover scraps, and repeat with the remaining dough.
4. Preheat oven to 350° F. Bake the cookies on the middle rack of the oven for 8-10 minutes. Cool on the baking sheet 5 minutes, then transfer to a wire cooling rack to cool completely.
5. Meanwhile, make the frosting. In a medium bowl, whisk together the butter, powdered sugar, espresso (if using), vanilla, and cream until smooth and drizzly. If needed, thin the glaze by adding additional cream, 1 tablespoon at a time, until drizzly. 
6. Decorate each cookie as desired with frosting and sprinkles. Enjoy!
