In a small bowl, blend together the chai spices. You will not need all of this mixture for this recipe.
In a large bowl, beat room temperature butter and sugar until light and fluffy (about 2 minutes or so). Add vanilla.
In a separate bowl, add the flour, salt and 1 tsp TOTAL of the chai spice mixture.
Add dry ingredients to wet ingredients and mix until combined.
Place dough on plastic wrap and shape into a rectangular log about 2 inches tall.
Chill for at least 1 hour.
Slice into 1/2 inch pieces and arrange on an un-greased baking sheet about 2 inches apart. Take a fork and lightly press down on the top (you can make this into any pattern you like). This prevents the cookies from puffing up too much. They should look like little dominos.
Bake at 325 for 9-11 minutes until the edges become golden brown.
