Line a baking sheet with parchment or a silicone baking mat.
In top of double boiler over low heat, melt chocolate, stirring frequently, until ¾ chocolate pieces are melted, only slightly warm to the touch. Remove pan from heat.
Stir in tea leaves; continue stirring until chocolate is melted and tea is evenly distributed.
Pour mixture onto baking sheet and spread evenly to ⅛-inch thickness. Let come to room temperature, allowing bark to solidify, about four hours. When set, break into pieces.
Store in airtight, covered container at room temperature.
