I was looking for a Chai cake recipe that would be close to what was offered at a local coffee shop we frequent. I also wanted a recipe that could be easily modified to use a box mix. Looking at three or four Chai cake recipes on the internet, this one looked the best for my purposes.I used Duncan Hines (it was on sale) Spice Cake Mix and added the spices mentioned in this recipe: cardamom, ginger, cinnamon, etc. I followed the box directions for making the cake but instead of water I used Chai tea made from dissolved Chai drink package. (from SeriousChai.com) It turned out EXCELLENT. Esp. with the icing. It was so close to the coffee house version we were ecstatic. I plan to try it with Betty Crocker''s Spice Cake mix next just to see what the difference might be.
