1Heat oven to 400°F. Grease bottom only of 8x4- or 9x5-inch loaf pan with shortening or cooking spray.
2In large bowl, beat granulated sugar and butter with electric mixer on medium speed until fluffy. On low speed, beat in tea, 1/3 cup milk, 2 teaspoons vanilla and the eggs until ingredients are well combined (will appear curdled). Stir in remaining bread ingredients just until moistened. Spread in pan.
3Bake 50 to 60 minutes or until toothpick inserted in center comes out clean (do not underbake). Cool in pan on cooling rack 10 minutes. Loosen sides of loaf from pan; remove from pan to cooling rack. Cool 30 minutes.
4In small bowl, stir powdered sugar, 1/4 teaspoon vanilla and 3 teaspoons of the milk, adding more milk by teaspoonfuls, until spreadable. Spread glaze over bread. Sprinkle with additional cinnamon. Cool completely, about 2 hours, before slicing. Wrap tightly and store at room temperature up to 4 days, or refrigerate up to 10 days.
