Cake

1. Preheat to 375°F, and position the racks in the center and lower thirds. 
2. Butter three 9-by-2-inch round cake pans, and line with parchment paper. 
3. Butter the paper, and dust the pans with flour; tap out excess flour. 
4. In a medium bowl, combine the chocolate with the tea and vanilla; let stand for 2 minutes, then stir until the chocolate is melted. 
5. In another medium bowl, whisk the eggs with the oil until pale yellow, then whisk in the sour cream. 
6. Gradually whisk in the melted chocolate mixture until smooth. 
7. In the bowl of a stand-mixer fitted with the paddle, combine the flour with the sugar, baking soda, cinnamon, and salt; mix well. 
8. At medium speed, beat in the wet ingredients in three batches until just incorporated. 
9. Scrape down the sides of the bowl, and beat until the batter is smooth. 
10. Pour the batter evenly into the pans; gently tap the pans on the counter to release any air bubbles. 
11. Bake for about 35 minutes, until a toothpick inserted in the center comes out clean; shift the pans halfway through baking. 
12. Let the cakes cool completely, then carefully invert onto a rack, and peel off the parchment paper. 

Ganache

1. In a medium saucepan, bring the cream, butter, sugar, and salt just to a simmer over moderate heat, stirring to dissolve the sugar. 
2. Remove from heat, and add the chocolate; let stand for 2 minutes, then stir smooth. 
3. Stir in the tea and vanilla. 
4. Let cool completely, stirring occasionally. 
5. Transfer one cake to a cake stand. 
6. Spoon one-fourth of the ganache on top and spread in an even layer. 
7. Top with another cake and one-fourth of the ganache. 
8. Cover with the third cake, and spread the remaining ganache over the top and side of the cake. 

Cranberries

1. In a small saucepan, combine the water and sugar, and bring to a boil; cover and set aside to cool completely. 
2. Toss the cranberries in the simple syrup, drain, and then chill for about 15 minutes. 
3. Roll the cranberries in the some sugar to coat, spread out on a plate, and then chill for an hour before serving. 

* For my brisk brew, I used 6 tablespoons of PGTips with 1200ml water.
