Add the dry ingredients together (flour, sugar, tea, baking soda, salt, cinnamon) and stir. You need to cut open the bags of chai tea and pour out the spices. Then add the water, oil and vanilla. Add the vinegar right before you put it in the oven, you need to mix the vinegar in well. Cook at 350 for 40 minute to an hour. Or until you can put a toothpick in the middle and it comes out clean. I ice it with vanilla icing.
