Slowly add the oil. Slowly add the 1-1/2 cups flour. Then, slowly add the tea which the baking soda was dissolved in. Then add cinnamon. Add some more flour (about 1/2 cup) until mixture is thick but still will pour easily into a greased and floured 13x9 pan.
Bake at 350 degrees 50-60 minutes, or until a toothpick inserted in center comes out clean.
