Brew the tea leaves with 8 ounces of hot water for 5 minutes. Remove the strainer or tea bag and add 1/2 cup of ice and stir until all the ice is melted to cool down the tea.
Froth the oat milk with the cinnamon, ginger, and vanilla until doubled in size.
Pour the cooled tea over ice in two glasses and top each with the cold foam. Enjoy!
