Chai Spice Baking Blend

As part of my current obsession with chai, I have been refining my chai spice baking mix for seasonal baking treats. I'll be posting my pumpkin chai snickerdoodle cookie recipe later this week, using this blend, but it can easily be used in muffins, cakes, or any other recipe that would do well with a warm, autumnal flavor.
