Preheat oven to 350 degrees F (180 degrees C). Grease and flour a 9 inch round cake pan.
In a medium bowl, sift together the flour, cocoa powder, baking powder, baking soda and salt. Set aside.
In a large bowl, cream together the butter and sugar until light and fluffy. Beat in the eggs one at a time, and then the vanilla extract and cooled black tea.
Add the dry ingredients alternately with the buttermilk, mixing until just incorporated. Pour the batter into the prepared pan.
Bake for 40 to 45 minutes, or until a toothpick inserted into the center of the cake comes out clean. Let cool in the pan for 10 minutes, then turn out onto a wire rack to cool completely.
