Begin by placing two black tea bags in a measuring cup or heatproof container.

In a saucepan, heat 1 cup of whole milk over low heat until steaming.

Carefully pour the hot milk over the tea bags in the measuring cup.

Allow the mixture to steep for about 10 minutes.

While the tea mixture is still warm, add your preferred sweetener.

Once sweetened, loosely cover the mixture to let it cool at room temperature for about 30 minutes.

After cooling, tightly cover the mixture with plastic wrap and refrigerate until completely chilled.

When ready to serve, fill a glass with ice cubes, then pour the chilled tea mixture over the ice.
