Preheat oven to 350 degrees. Grease and flour a bundt pan and set aside.
Add tea bags to hot water and steep for five minutes then remove the bags.
2 black tea bags, ¾ cup hot water
Beat butter with mixer until it becomes smooth and a pale shade of yellow (about two minutes). Add sugar and cream together for three minutes. Then mix in eggs, one at a time, followed by ½ cup of the tea, and vanilla extract.
1 pound butter, 1 ¾ cups sugar, 6 eggs, 1 teaspoon vanilla extract
Meanwhile, whisk together flour and sea salt. Add half of this dry mixture to the wet mixture and mix until just combined then repeat with remaining flour mix. Give the batter a few stirs by hand to make sure no dry pockets remain.
4 cups flour, ½ teaspoon fine sea salt
Transfer batter into prepared pan then bake on middle oven rack for about 1 hour and 20 minutes or until a toothpick inserted into multiple parts of the cake comes out clean.
Remove cake from oven and let it sit in pan for about 10 minutes then carefully invert it onto a plate to finish cooling to room temperature.
While cake cools, dissolve the brown sugar and remaining black tea. Use toothpick to poke multiple holes into top of cake then spoon glaze over top.
2 tablespoons brown sugar
