In a teapot or heatproof container, add the black tea leaves.
Pour boiling water over the tea leaves and let steep for about 3-5 minutes, depending on your preferred strength.
Strain the brewed tea into a separate container, discarding the tea leaves.
Stir in the sweetened condensed milk and granulated sugar until well combined. Adjust the sweetness according to your preference.
Allow the tea mixture to cool to room temperature.
Fill two glasses with ice cubes.
Pour the cooled tea mixture over the ice cubes, filling the glasses about three-quarters full.
If desired, drizzle evaporated milk over the top for extra creaminess and flavor.
Stir gently to combine the tea and milk.
Serve the Thai Ice Milk Tea immediately and enjoy its creamy and refreshing taste.
