Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
Cream together butter and honey until light and fluffy.
Beat in the egg, 1 tablespoon brewed black tea, and vanilla extract.
In a separate bowl, whisk together the Jiffy mix and all-purpose flour.
Gradually add the dry ingredients to the wet mix, stirring until combined.
Chill dough for 20 minutes.
Drop spoonfuls of dough on the baking sheet, and bake 10-15 minutes.
While the cookies bake, prepare the glaze by mixing 1 tablespoon cooled black tea with powdered sugar.
Retrieve cookies from oven, brush with glaze, and return to bake for 5-10 minutes, or until tops look golden.
Cool on the baking sheet 5 minutes before transferring to a wire rack to cool completely.
