INGREDIENTS
For the cake:*
1/2 cup
Dutch-processed cocoa powder, plus extra for dusting pans
1 1/2 cups
all-purpose flour
1 tsp
baking soda
1/2 tsp
baking powder
1/4 tsp
salt
1 1/4 cups
boiling water
4 oz
unsweetened chocolate, finely chopped
1 tsp
espresso powder
10 tbsp
unsalted butter, softened
1 1/2 cups
packed light brown sugar
3
large eggs
1/2 cup
sour cream, room temperature
1 tsp
vanilla extract
For the filling, frosting and garnish:
8 oz
white chocolate, finely chopped
1 lb
unsalted butter, softened
1 cup
confectioners’ sugar
1/8 tsp
salt
4 tbsp
heavy cream
2 tsp

*I made three 9-inch cake layers, and increased the amount of cake batter by 50%. I made the regular amount of filling and frosting called for in the recipe, and it was just enough.
