Heat oven to 350F. Coat an 8-cup fluted tube pan with cooking spray.

Boil water and pour 1 cup of water over the tea bags. Steep the tea in the water 3-5 minutes. Remove the tea bags and set the brewed tea aside.

Using a mixer, beat the butter, eggs, and granulated sugar until fluffy. Blend in the melted chocolate. Beat in the flour, baking soda, baking powder, salt, yogurt, and brewed tea.

Pour into pan. Bake 40-50 minutes or until a skewer inserted into the cake comes out with a few crumbs attached.

Remove from oven and let stand 5 minutes. Turn out of pan and cool. Dust with powdered sugar, slice, and enjoy!
