Bring water to a boil in a small pot. Add in the tea bags and remove the pot from the heat. Cover with a lid and steep for 5 minutes.
Discard the used tea bags. Return the pot of tea to medium heat and add the brown sugar.
Stir occasionally and heat for 3-5 minutes or until all the sugar has completely dissolved. Remove from heat and stir in heavy cream. Set aside.
Boba Pearls
In a small bowl, stir together the glutinous rice flour, brown sugar, and hot water until it becomes a thick, sticky paste.
Thoroughly flour hands and fingers and pinch off small bits of dough. Roll into balls between your fingers and toss rolled pearls in a bowl with glutinous rice flour to coat.
Add finished pearls to a small pot of boiling water and stir. The water will bubbly up briefly after a minute. Boil until the pearls float to the surface, about 3-4 minutes.
Strain the cooked pearls from the water and return them to the empty pot or a small saucepan.
Add brown sugar and water to the pearls and heat on medium heat. Let the brown sugar syrup boil for 5-10 minutes until it thickens and coats the pearls.
Add 1-2 tablespoons of pearls to each popsicle mould. Fill the rest of the mould with milk tea. Give the pearls a stir as you insert each popsicle stick.
Freeze for at least 4 hours or overnight. When ready to serve, run the sides of the popsicle mould under warm water to loosen popsicles.
